Mathematics Ag-tivities Grade and standard aligned mathematics activities that teach students about agriculture. Mathematics Ag-tivities Grade and standard aligned mathematics activities that teach students about agriculture. Introduction: Mathematics can be incorporated into all areas of the curriculum. This book provides lessons that teach mathematics concepts while educating students about agriculture. At the beginning of each chapter, there is a short explanation of the concepts covered in the mathematics substrands for that grade level. The substrands Virginia has adopted include: Number and Number Sense; Computation and Estimation; Measurement; Geometry; Probability and Statistics; and Patterns, Functions, and Algebra. The lessons that follow provide the numbers for the Virginia Standards of Learning, necessary materials, background information, and the procedure. Extensions and pictures are also included. Entire SOL’s are listed in a separate section, and the Masters for the activities are located at the end of this book. Each lesson incorporates interesting information about agriculture with mathematics concepts. Students gain skills to solve math problems while learning about agricultural facts about livestock, various commodities, and plant growth.

The concept of one-to-one correspondence develops and flourishes during this year. Computation and Estimation Kindergarten students add and subtract up to 10 concrete objects. Measurement Weather and seasons are incorporated into early childhood lessons. Geometry Simple plane figures are identified by kindergarteners. The location of objects is also an important concept for young children to understand. Probability and Statistics Not only are students expected to understand numerals, but the children are also required to use tallies as a form of counting. Picture and object graphs are also taught during this grade. Patterns, Functions, and Algebra Naming patterns and contributing objects to extend the patterns are skills gained during kindergarten. The students’ abilities to classify objects are not only an important skill in mathematics, but in science as well. Egg Carton Math Standards of Learning Math: K.1, K.6 Science: K.7, K.9 English: K.2 Materials Pom-poms, fake eggs, or other small objects that can fit inside an egg carton 3-5 Egg cartons (diagram found on p. 88) Background Knowledge Young children can benefit from concrete examples of abstract ideas. This lesson allows students to count objects and begin to understand addition problems that equal 10 or less. Also, egg cartons represent one commodity Virginia farmers produce. Chicken eggs account for $77.1 million in Virginia. There are nearly 900 chicken farms in the Commonwealth. Procedure 1. Create the manipulatives shown above. Practice counting with the students prior to the activity. 2. Discuss eggs, chicks, and chickens and the importance of them for Virginia farmers. Read books such as Eggs and Chicks by Fiona Patchett or From Egg to Chicken by Gerald Legg. 3. Use the egg cartons and objects to practice counting, number recognition, addition, and subtraction. Extension Create the lifecycle of an egg as it grows into a chicken. Also, this lesson could be helpful for older students struggling with the concept of addition and/or subtraction. 2 Seasons on a Farm Standards of Learning Math: K.8, 1.11 Science: K.9, 1.7 Materials Book that incorporates farming and seasons, such as Seasons on a Farm by Nancy Dickmann Scissors Glue Large chart paper divided into four sections titled: fall, winter, spring, and summer Watering can Seed packet Toy tractor An example of corn Worksheet (see p. 89) Background Knowledge Children can observe changes in weather—from a hot and sunny summer, to a cold and snowy winter. It is important for young students to understand seasons and that different phenomenon occur during certain times of the year. Providing examples of activities on a farm throughout the seasons allows children to associate concrete actions to the abstract concepts of seasons and weather changes. Procedure 1. Read students Seasons on a Farm by Nancy Dickmann, or a similar book describing farm life during specific seasons. 2. Discuss the various jobs farmers must complete, especially which season they get them done. 3 3. Have the concrete objects such as a watering can, seed packet, toy tractor, and corn, and ask students to sort them into the appropriate season on the chart paper, i.e. corn goes in the fall (harvest). 4. Explore other events that occur during the four seasons. 5. Have students cut out the pictures on the worksheet and glue them in one of the boxes underneath the appropriate season. Then ask them to draw a picture of what other things they do during the fall, winter, spring, and summer in the other box. Extension Write sentences about your favorite season and what you do during that time. 4 Below or Above? Standards of Learning: Math: K.12 Science: K.4 Social Studies: K.3 Materials: Wiggling Worms at Work by Wendy Pfeffer and Dirt by Steve Tomecek Worksheet (see p. 90) Scissors and glue Background Knowledge: Like vegetables, fruits, flowers, and other plants, some animals live below the earth and some live above it. Living below the earth can help plants grow because these animals help aerate and rotate the soil. Understanding the terms “above” and “below” can help students identify different farm animals and where they live. Procedure: 1. Complete a book walk using Wiggling Worms at Work by Wendy Pfeffer and/or Dirt by Steve Tomecek. These texts are slightly advanced for Kindergarten. However, book walks, or skimming through the books and leading a discussion about them, could provide essential information at the appropriate level. 2. Conduct a conversation about which animals live underground and reasons why they might live there (specifically animals found on a farm). 3. Ask the students to cut out the pictures and glue the animals where they live: above or below ground. Extension: Describe the different varieties of plants that live above and below the ground. Discuss which parts of plants we eat—the tops, middles, or bottoms. 5 Cow Glyphs Standards of Learning: Math: K.13, K.14, 1.14, 2.17 Science: K.1, 1.1, 2.1 English: K.2, 1.3, 2.3 Materials: 2 books involving cows, such as Cows on the Farm by Mari C. Schuh and Cows by JoAnn Early Macken White paper plates with one hole punched out for the tail Several construction paper squares of the following colors: o Red, orange, yellow, light green, dark green, light blue, dark blue, purple, pink, brown, black, white There must be enough colors to represent each month your students have birthdays. For example, if no one has a September birthday, you would only need 11 colors. Extra black, brown, and/or white paper for ears Black circles to represent spots (between 75 and 125, depending on the age and number of students) Black pipe cleaners White pipe cleaners Chart paper (for tallying) Crayons Scissors (1 per student) Glue (1 per student) Glyphs key: o Color of Ear Tag = month of birthday o Number of Spots = age of child o Color of Pipe Cleaner Tail = favorite cow book o Black < “Book 1” o White < “Book 2” 6 Background Knowledge: By using symbols, this project looks like a cow but everything has a specific meaning. Tallying each symbol practices one-to-one correspondence and data collection. Picture and object graphs could then be constructed using the information gathered. Tagging is used on farm animals to identify and keep track of their health. The tags act as their “birth certificates.” Everyone has a birthday, and this is a way farmers can remember important information about their cows. Procedure: 1. Read students both cow books. 2. Provide the supplies indicated above. 3. Review the following directions as a group and have a chart posted for students to refer to: a. Make ears and attach them to the paper plate. b. Draw eyes, a nose, and a mouth on the paper plate to make the face of the cow. c. Glue the color square that represents your birth-month to one of the ears. Write your name and birthday on the tag. d. Glue the number of circles that matches your age on the cow’s face. e. Choose a black pipe cleaner for “Book 1” and a white pipe cleaner for “Book 2,” depending on which was your favorite. Stick the pipe cleaner through the hole and twist the end to secure the tail. 4. Display cows once they are dry. 5. With the class tally: a. How many people have their birthdays in each month. b. How many people are 4, 5, 6, etc. c. How many people like “Book 1” and how many people like “Book 2.” 6. Display the information in a chart. 7. Graph the tallies in a bar chart, object chart, and/or picture chart. Extension: Write a story about what you would do if a cow came to your birthday party or was a birthday present. 7 Farmyard Tangrams Standards of Learning: Math: K.16, K.11, 1.12, 1.17, 2.20 Science: 1.5, 2.4, 3.5, 3.6 English: 1.1, 1.2, 2.3, 3.2 Materials: Tangrams Tangram patterns in the shapes of farm animals found at www.agintheclass.org Background Knowledge: Tangrams allow children to create patterns. These manipulatives come in many different shapes, including squares and triangles. Shapes can be used to represent different things, including animals and equipment found on a farm. Procedure: 1. Read a book about farm animals, such as Barnyard Banter by Denise Fleming, Big Red Barn by Margaret Wise Brown and Felicia Bond, or Farm Alphabet Book by Jane Miller. 2. Allow students to explore the tangrams for several minutes. 3. Provide tangram patterns and ask students to put the tangrams on the picture until all of the pieces fit. Provide several different options for students to use. 4. Ask students to create their own tangram image of a farmyard animal. After students have had enough time to make their own creations, allow students to take a “Barnyard Tour” and observe the animals created by their classmates. Extension: Kindergarten students can also identify, describe, and trace plane geometric figures. Older students can express through oral or written language facts about their tangram animal, such as the name used for the baby of that animal. 8 9 10 1st Grade Number and Number Sense Counting to 100 is a goal for 1st graders. Developing an understanding of place value and fractions both begin during this year. Computation and Estimation Students begin to add and subtract numbers up to 18. Story and picture problems are incorporated into lessons. Measurement The value of coins is explored by first graders, as well as nonstandard units. Geometry Objects in the environment can be sorted into plane figures by students in 1st grade. Also, shapes are identified by the number of sides, vertices, and right angles they have. Probability and Statistics Data collection techniques are practiced by students. Interpretive words such as more than and less than are used by the children. Patterns, Functions, and Algebra Students still continue to sort objects and extend patterns. Equality is introduced with the equals (=) sign. 11 Apple Orchard Math Standards of Learning: Math: 1.1 Science: 1.4 English: 1.1 Materials: 1 copy of a complete 100s chart per student (see p. 91) 1 copy of a blank 100s chart per student (see p. 92) Background Knowledge: Counting to 100 is an essential skill young children must acquire in order to learn higher level math concepts. Practicing counting and writing the numbers helps children gain number sense. Apples are concrete, everyday objects students know about and can use to count. Also, apples are an important Virginia crop—about 12,000 acres of apples are harvested every year. Discussing apples in the fall can teach children about harvesting this abundant crop. Virginia ranks sixth in the United States for apple production. Procedure: 1. Practice counting on the completed 100s chart. Discuss counting by tens down the chart (10, 20, 30, 40, etc). Ask students to find certain numbers on the chart, such as 76, to support their knowledge of numbers. 2. Ask the students to complete the Apple 100s Chart. Count the first row since it is already filled out. Help them with the next row (11 is done for them). Then allow them time to finish the chart. Some numbers are already filled in to keep students on track. Provide the completed 100s chart if students are still having difficulty counting and writing numbers. 12 Extension: Students can discuss the life cycle of an apple. Apple picking, apple pie baking, and other fall activities can be completed alongside this lesson. Read Amazing Apples by Consie Powell and have students participate in poems about the fruit and fall. 13 Fruits and Veggies We Eat Standards of Learning: Math: K.13, K.14, 1.7, 1.14, 2.10, 2.20 Health Education: K.1, 1.2, 2.2 Materials: Chart paper Examples of fruits and vegetables, as well as their cost displayed for students to read Coin sets that equal the cost of favorite fruits and vegetables Background Knowledge: Understanding coins can be difficult; each one is a different value and size. The values of money are abstract for children, but applying it to real life situations can make it easier to comprehend. Fruits and vegetables are grown in Virginia and can be purchased in farmers markets, grocery stores, and food vendors across the state. Virginia produce includes: soybeans, tomatoes, apples, potatoes, grapes, snap beans, sweet corn, peaches, watermelon, and cabbage. Procedure: 1. Discuss with students the importance of eating a well-balanced, healthy meal. 2. For a minimum of 10 days, ask students after lunch what produce they ate. 3. Tally on chart paper the student responses. Graph the students’ lunchtime consumption of fruits and vegetables after collecting all of the data. 4. On the last day, ask students about their favorite fruits and vegetables. Tally and graph their responses. Compare the two graphs and ask questions about the differences you find. 5. Give students different amounts of money that equal only 1 fruit or vegetable choice. Ask them to determine the value of their coins. Show them options for different fruits and vegetables, along with the price. Ask the students to go to 14 which ever food item they can afford with the exact amount of money they have. Allow them to work together if the children need help identifying or adding the money, or finding their appropriate produce. Extension: Discuss the nutritious values of fruits and vegetables, and how students can create balanced meals. Also, as the children become more comfortable with money and how it is used, allow them to exchange coins to make exact change for items they would like. For example, if a banana costs $0.79, a student with $0.80 cents can ask to exchange a nickel for 5 pennies in order to have exact change (with 1 penny left over). 15 Classifying Virginia Products by Shape Standards of Learning: Math: K.11, 1.12 Science: K.1, 1.1 English: K.2 Materials: Chart paper large enough to be used as a grid on the floor for the children to see, with sections titled: triangle, rectangle, square, and circle with a picture beside the shape. Virginia products and their general shapes (provide a picture or an example): Apple (circle) Chicken nugget (circle) Slab of fish (rectangle) Hamburger patty (circle) Evergreen tree (triangle) Egg (circle) Flower petal (triangle) Slice of bread (square) Cereal box (rectangle) Tomato (circle) Soy bean (circle) Green bean (rectangle) Ear of corn (rectangle) Bunch of grapes Potato and/or sweet Cotton ball (circle) (triangle) potato (circle) Cucumber (rectangle) Hay bale (circle) Wool (circle) Strawberry (triangle) Peach (circle) Blanket (square) Cracker (square) Watermelon (circle) Sausage link (rectangle) Cheese (triangle, square, Wheat (rectangle) Pumpkin (circle) circle, or rectangle) Lumber (rectangle) Bacon (rectangle) Peanut (circle) Turkey meat (square) Background Knowledge: All types of shapes occur in nature, including triangles, squares, rectangles, and circles. Each shape is unique according to the number of vertices, right angles, and sides. Virginia produces many products that can be classified by their general shapes. 16 Procedure: 1. If available, read books such as Food for Thought by Joost Eiffers and Saxton Freymann or The Shapes We Eat by Simone T. Ribke. 2. Discuss shapes and the characteristics of each figure. 3. Ask the children, one at a time, to sort the Virginia products by their shape. Extension: Graph the number of products for each shape. 17 Farmyard Patterns Standards of Learning: Math: K.16, 1.17, 2.20 English: K.1, 1.1 Materials: Farm-related pattern book, such as Farm Patterns by Nathan Olson Interactive Bulletin Board Background Knowledge: Patterns can be created by students using letters, sounds, rhythms, or objects. Patterns also occur in nature. This lesson allows students to explore natural patterns and create patterns with farm pictures using an interactive bulletin board. Procedure: 1. Instructions for the interactive bulletin board: o Create a title for the board, such as “Pattern Practice” o Prepare several patterns for the students to finish using agricultural objects: tractors, hoes, apples, corn, tomatoes, pumpkins, hay bales, soy beans, peanuts, chickens, cows, horses, pigs 2. Explain to students what a pattern is. Provide examples of types of patterns and where they might occur. 3. As a class, practice making patterns by using oral language: red white red white or Y Z Y Z 4. Read the book Farm Patterns by Nathan Olson. Help the students find the patterns the book illustrates that can be seen on a farm. 5. Present the students with the beginning of a pattern on the bulletin board. Ask the students what kind of pattern it is (ababab, abcabcabc, aabaacaad, etc). Have one child finish the pattern and explain why they made that choice. Work through the prepared patterns. 18 6. If time permits, allow several children to create their own patterns with the objects provided. Extension: Allow students to make their own patterns using stickers or other art supplies and display them around the room. 19 20 2nd Grade Number and Number Sense Three-digit numerals, and an understanding of each place value, are the focus of 2nd grade. Increasingly more complicated fractions and skip counting are introduced to students. Computation and Estimation Addition and subtraction facts up to 20 should be recalled by students. An understanding of estimation is acquired for subtraction and addition. Measurement Specific measurements are gathered and understood by students including cups, pints, quarts, and gallons. Geometry Lines of symmetry are drawn by students and solid figures are introduced. Probability and Statistics Data from experiments is used to create graphs and predict outcomes in 2nd grade lessons. Patterns, Functions, and Algebra Not only are object patterns still used in 2nd grade, but numeral sentences are also incorporated. The non-equals sign, 21 ≠, is discussed. Farm Fractions Standards of Learning: Math: 2.3 Materials: Apple Fractions by Jerry Pollatta Examples of the following: o String beans in a pod o Peanuts in the shells (If there is an allergy, show pictures instead) o Egg carton o Horse figurines or pictures (to go in “stalls”) Chart paper with 3, 6, 8, and 10 “stalls” drawn on it Worksheet (see p. 93) Background Knowledge: Fractions can be illustrated using every day items. Students in second grade work with halves, thirds, fourths, sixths, eights, and tenths. This lesson uses agricultural items, such as eggs, beans, peanuts, and horse stalls to teach students about fractions. Procedure: 1. Discuss with students what a fraction is. Provide examples of how to write fractions and discuss with students what the fraction means. 4. Open the bean pod. Show students that 4 beans come in a pod. a. Ask the students what the fraction would be if only 2 beans were there (2/4 or ½). b. Ask the students what the fraction would be if only 1 bean was there (1/4). c. Ask the students what the fraction would be if 3 beans were there (3/4). 5. Open the peanut shell. Show the students that 2 peanuts come in a shell. i. Ask the students what the fraction would be if only 1 peanut was in the shell (1/2). 22 6. Lay out the chart paper with the “stalls” drawn on it. 7. Show students the farm animals in the stalls. Use the different number of stalls to show thirds, sixths, eighths, and tenths. a. Put 2 horses in the 3 stall section. How many stalls are used? 2 out of 3 (2/3). b. Put 1 horse in the 6 stall section. How many stalls are used? 1 out of 6 (1/6). c. Put 6 horses in the 8 stall section. How many stalls are used? 6 out of 8 (6/8). d. Put 3 horses in the 10 stall section. How many stalls are used? 3 out of 10 (3/10). 8. As a review, ask students to complete the worksheet. Extension: Ask students to create their own farm fraction. Also, twelfths are not taught until 3rd grade but using the egg carton can introduce students to fractions with 12 as the denominator. 23 Farm Animal Skip Counting Standards of Learning: Math: 2.4 Materials: Interactive Bulletin Board: o Multiple cut outs of a crab o Multiple cut outs of a chicken o Multiple cut outs of a turkey o Hand prints cut out of construction paper (for turkey feathers) o Numerals cut out *Pictures/templates can be downloaded from clipart or created using Die-Cuts. Background Knowledge: Skip counting helps students begin a foundation for multiplication. Using agricultural animals to practice skip counting provides examples students can rely on for counting if necessary. Chickens are the top commodity for Virginia farmers and help students practice counting by 2s because of the two legs on the animal. Crabs have 10 appendages, 8 legs and 2 claws, and are a great way for students to practice counting by 10s. These animals are gathered in the Chesapeake Bay. Turkeys are the fourth highest commodity for Virginia farmers, and hand prints can be used to represent their feathers. The hand prints also represent groups of 5 and help students learn their multiples of 5. Procedure: 1. Set up a bulletin board entitled “Farm Animal Skip Counting.” 2. Cut out several crabs, chickens, turkey bodies, and hand prints. a. Write 2, 5, and 10 on a few examples to use as starter for the students. 24 3. Prepare several turkeys with construction paper. On the belly of some turkey bodies, write a multiple of five, but do not attach the feathers. Provide students with enough hand print feathers (with 5 fingers on each) to match the number on the bodies. For other turkeys, include the feathers and ask the students to determine the multiple of 5. 4. On the bulletin board, post several multiples of 10 and ask the students to put up the correct number of crabs. Also, put up some examples of groups of crabs, and ask the students to determine the multiple of 10 they represent. 5. On the bulletin board, post different examples of multiples of 2. Ask the students how many chickens match the multiple of 2. Post several groups of chickens, and ask the students to explain the multiple of 2 the chickens represent Extension: The use of an interactive bulletin board can also be applied to fractions. 25 Crop Picture Graphs Standards of Learning: Math: 2.8, 2.19, 2.21 Materials: Chart paper with the following key: Create picture graphs of the crops three different farmers produce (see p. 94) Worksheet (see p. 95) Background Knowledge: Picture graphs can be used to teach data analysis and computation. By creating a key for the picture graph, students can solve addition and subtraction problems, and create their own numerical sentences. Also, apples, pumpkins, and corn are agricultural commodities grown by Virginia farmers. Procedure: 1. Display the graphs from page 94. Discuss what each picture represents. 2. Ask the students questions such as: a. Which farmer produces the most apples? b. How many more apples does Farmer Dan produce than Farmer Sally? c. How many more corn stalks does Farmer T.J. need to plant in order to fill the row, if each row has 120 corn stalks? 3. Provide students with the worksheet attached. Ask them to use the key to solve the problems. Then ask students to create their own numerical sentences that use the key. Extension: Practice subtraction problems using the same method. 26 Scarecrow Measuring Standards of Learning: Math: 2.11 Science: 2.1 Materials: Paper plate Yarn Brown construction paper for gallon body* Red construction paper for quarts* Orange construction paper for pints* Yellow construction paper for cups* Extra construction paper Examples of the following measuring containers: gallon, quart, pint, cup *The whole pieces of construction paper must be the same size. Background Knowledge: Measuring tools, such as gallons, quarts, pints, and cups, are important for cooking and buying food products. Milk comes in a gallon jug, strawberries are packaged in quarts, consumers can buy pints of blueberries, and soybeans are measured in cups. Students need to understand how to convert units: 2 cups = 1 pint, 2 pints = 1 quart, and 4 quarts = 1 gallon. Procedure: 1. Read students Scarecrow by Cynthia Rylant. Farmers use scarecrows to keep pests out of their farms in order to preserve their crops. This book beautifully describes the peaceful, but important, purpose of a scarecrow. 2. Allow students to create a face for the scarecrow. Use the yarn for hair and the additional construction paper for a hat. 3. Show the gallon container. Discuss and illustrate how much it holds. Explain 27 4. 5. 6. 7. 8. that you are using the brown piece of paper to represent a gallon. Repeat this step with the other measurements. Use the whole piece of brown construction paper for the body and write “Gallon” in the middle. Attach the head to the top of the brown paper (see picture). Cut the red paper into 4 equal pieces and write “Quart” in the middle of them. Glue one on the right side of the brown paper, one on the left side of the paper, and two on the bottom of the paper. Cut the orange paper into 8 equal pieces. Write “Pint” on the papers and glue two to each quart. Cut the yellow paper into 16 equal pieces. Write “Cup” on the papers and glue two cups to each pint. Discuss the conversions from cup, to pint, to quart, to gallon. Bring in items that are measured in these ways so students have a representation of the unit. a. Milk: gallon b. Quart: strawberries c. Pint: blueberries d. Cup: soybeans Extension: Provide students with a recipe that uses some, if not all, of these units. Help them practice measuring ingredients and cook the food item. Paper Plate for Head Gallon Brown Paper Quart Red Paper 28 Pint Orange Paper Cup Yellow Paper Produce Printing Standards of Learning: Math: 2.15 Science: 2.8 Materials: Large pieces of white paper (1 per student) Several different paint choices for students Paint brushes or sponges Produce stamps: o Apples: cut in half horizontally o Peppers: cut horizontally into rings o Carrots (cut if desired) o Ears of corn o Potatoes: can cut symmetrical designs into it to create a stamp o o o o Leaves Onion Peanuts Cucumbers: sliced horizontally o Baby pumpkins: cut horizontally or vertically o Grapes: whole or cut o Squash: whole or cut Background Knowledge: Symmetry can be found in nature. Virginia’s produce can be used to demonstrate natural symmetry. This lesson allows students to investigate fruits and vegetables that Virginia farmers grow, as well as the concept of symmetry. Procedure: 1. Pass out the supplies to the students. Provide several examples of produce for the children to paint with. 2. Allow the children to put paint on the produce and stamp the images on the paper. Try to keep each image spaced out in order to draw lines of symmetry. 29 3. After the students have time to stamp with the produce, discuss symmetry. Objects are symmetric if one half of the image is the mirror image of the other half. 4. After the paint is dry, ask the students to find lines of symmetry in their paintings and draw them on their produce prints. Extension: Discuss the parts of the produce they see (seeds, veins, etc). 30 31 32 3rd Grade Number and Number Sense Students in 3rd grade should read and write six-digit numerals. They should also recall basic multiplication and division facts. Mixed numbers and fraction inequalities are also taught in 3rd grade. Computation and Estimation Students are expected to solve single- and multi-step addition and subtraction problems. Arrays, sets, and number lines model multiplication problems for 3rd graders. Measurement Larger quantities of money must be recognized by 3rd grade students. Perimeter and area of polygons are measured by students. Geometry Comparisons between plane and solid figures teach students how to identify them by specific characteristics. Probability and Statistics Line plots are added to the types of graphs students can create. Patterns, Functions, and Algebra Patterns with numbers, tables, and pictures are created by students. The children also investigate the commutative properties of addition and multiplication. 33 Watermelon Fractions Standards of Learning: Math: 3.3 Science: 3.8 Materials: Interactive Bulletin Board: o Paper plates cut into fractions and colored like watermelon o Equals signs o “What is missing=” signs o “Are the missing parts equal=” signs Samples of watermelon Background Knowledge: By third grade, students have had prior experiences with fractions. This lesson provides students with the opportunity to compare fractions and determine equivalency. Students can discover equal and non-equal watermelon slices, and how that relates to the missing fraction. Students can also learn about the life cycle of this Virginia-grown fruit. First it starts as a seed, and then sprouts into a leaf. A flower blooms and is pollinated. Then a small watermelon is formed, which grows until ripe. Procedure: 1. Take several white paper plates and cut them into the following fractions: a. Halves, thirds, fourths, fifths, sixths, eighths, tenths, and twelfths. 34 2. Color the fractions to make them look like watermelon. 3. Create various scenarios for fractions (allow students to use extra watermelon slices to determine the answers): a. Put up ½ and ask: What is missing? b. Put up 7/12 and ask: What is missing? c. Put up ¼ and ask: What is missing? d. Put up 4/6 and 2/3 and ask: Are the missing parts equal? e. Put up 4/6 and 4/8 and ask: Are the missing parts equal? f. Put up 1/5 and 2/10 and ask: Are the fractions on the board equivalent? Extension: Begin asking simple computation questions, such as ¾ + ¼ = ____. Also, review the life cycle of a water melon with the AITC lesson, “Watermelon Chain.” Read students Watermelon Wishes by Lisa Moser to see illustrations of the life cycle of watermelons incorporated into a heart-warming story. 35 Agriculture Arrays Standards of Learning: Math: 3.5, 3.6, 3.20 Materials: Chart paper o Practice array can be found on p. 96 Soybeans Cotton balls Background Knowledge: Arrays can be used to discover multiplication facts and the commutative property of multiplication. For example, a 2x3 array is similar to a 3x2 array. By providing concrete objects, students can understand how multiplication works and equality between facts. Cotton and soybeans are important agriculture commodities for farmers in Virginia. Before allowing students to use the manipulatives, ask them for any facts they know about cotton and soybeans. Then, share with them the following information: In 2008, 60,000 acres of cotton and 570,000 acres of soybeans were harvested. Soybeans are the 8th highest Virginia commodity, and cotton is 16th. One bale of cotton can make 215 pairs of jeans. Soybeans are made into different types of oils, soaps, cereals, and crayons. Read Why the Brown Bean was Blue: the Story of a Soybean Frown Turned Upside Down by Susan M. Pankey for more information about soybeans. Procedure: 1. Use large sheets of chart paper to create a large 12x12 array. 2. Bring in beans and cotton balls for the students to use. Allow students, one at a time, to create arrays that represent multiplication facts through the 12’s table. 36 3. Show different ways to set up multiplication problems. If a student is given 2x3, and the array looks like this: XXX, show the students 3x2: XX XXX XX XX 4. Pair students off. Give them cotton balls and soybeans to work with. Ask them to create 2 arrays for specific multiplication problems (i.e. 3x4 and 4x3; 5x6 and 6x5). 5. Check student work to ensure understanding. 6. To further review with the students, ask individual children to create arrays for new multiplication problems. Extension: Move from using concrete objects to abstract understanding through paper-andpencil assignments. Provide grids and ask students to color different arrays. 2x3 For the purpose of this picture, pumpkin seeds were used. 37 Apple Statistics Measuring and Statistics Unit: Apple Statistics Lesson 1 Standards of Learning: Math: 3.9, 3.10 Science: 3.1 Materials: Apples: have the same number of apples for each kind of apple, and give one apple to each child. The types of apples used for this lesson should include Granny Smith, McIntosh, Gala, Golden Delicious, and Red Delicious apples o Students should donate apples for the simulation of the activity. More than 2 of each kind of apple should be used. Plastic knives Paper plates Twine Rulers Scales or triple beam balances with weights Excel (if desired) Worksheets (see p. 97-100) Background Knowledge: There are many different types of apples, and Virginia produces 11 different varieties. There are 5 seed pockets in apples, and the number of seeds per carpel is determined by the vigor and health of the plant. This lesson investigates the circumference, weight, and number of seeds of different apples. Students will learn about different types of apples, practice determining circumference and weight, complete various statistical graphs and data collection techniques, and determine if there is a correlation between the variables. 38 Procedure: *This is a multi-step lesson. Please use the AITC lesson “Apple Statistics, Lesson 2” for the probability and statistics and English activities, which uses the data collected in this lesson. 1. Collect materials and set up scales/balances around the classroom. 2. Pass out the following to each student: student packet, 1 apple, plastic knife, paper plate, twine, and ruler. Ask students to write what kind of apple they have on the worksheet (provide examples so they know which kind they have). 3. Have students find the circumference and weight of their apple. Record on the data sheet. a. If students have not used twine to measure circumference, review the following steps: find the largest part around the apple, wrap twine around the apple, and mark the spot where the twine intersects. Measure the length of twine with a ruler. b. Provide instructions for weighing apples either on the scale or balance if students are unfamiliar with the processes (i.e. let scale equal zero and then set the apple on the scale to read the weight; or place the apple on one side of the balance and add weights until it is level). 4. Ask students to cut their apple in half. Count the number of seeds that are in the apple and record on the worksheet. 5. Collect student data and compile it for the students. a. Example of chart for class data (filled in with student collected data): Type of Apple Weight (in pounds) Circumference (in inches) Average # of seeds 6. Let them eat the apples! Talk about which kinds of apples the students enjoy eating. Extension: Healthy eating habits could be discussed. The life cycle of an apple can also be paired with this activity.

The other packet does not have a grid and the line plot is not labeled. Use whichever student packet that meets the needs of your students Excel (if desired) Procedure: *This is a multi-step lesson. Please use “Apple Statistics, Lesson 1” for the measurement activities which provides the data needed for this lesson. 1. Pass back each child’s packet and a copy of the total data set. a. Example of chart for class data (filled in with student collected data): Type of Apple Weight (in pounds) Circumference (in inches) Average # of seeds 2. Complete the following statistic activities that are applicable (instructions follow): a. Bar Graph: kind of apple vs. average seeds b. Line Plot: weight 3. Ask the following discussion questions: a. What type of food is an apple? b. Why do you think apples have different numbers of seeds? How does the size of the apple affect the number of seeds it has? c. Which kind of apple do you think would have the highest average number of seeds? 40 d. Are weight and circumference related? e. Who grows apples? f. How do you think the size of apples impacts farmers? i. I.e. packaging, price, livelihood, orchards, weather/climate, cooking, etc. Extension: Describe different types of literature, including legends, with your students. Books about the legend of Johnny Appleseed can be read, a discussion about different types of literature can be conducted, and this math lesson can incorporate apples. For a mathematics extension, the bar graph can be made using Excel: To create a chart with each apple type and the average number of seeds (use student data collected in Lesson 1): o Label A1: Type of Apple (this will be the x-axis) Enter the varieties of the apples in column A o Label B1: Average number of seeds (this will be the y-axis). Enter the average number of seeds for each type of apple in column B (align with appropriate apple variety). o Highlight the two columns (type of apple and average number of seeds) by holding the CTRL button and selecting the desired data. o On the tool bar, select “Insert” bar/column chart for the data. Make sure the chart selected has the titles of the chart, x-axis, and y-axis (usually choice 9). 41 Example Work *This is not the Student Packet* Apple Statistics Name ____________________ Type of apple: see chart Number of seeds in the apple: see chart Type of Apple Circumference (inches) Number of seeds Granny Smith 1 Weight (in pounds) .5 10 2 Granny Smith 2 McIntosh 1 McIntosh 2 Gala 1 Gala 2 Golden Delicious 1 .66 .51 .54 .56 .61 .5 11 10.75 10.75 10 10.75 10 2 3 5 8 7 4 Golden Delicious 2 Red Delicious 1 Red Delicious 2 .48 .57 .53 9.25 10 9.75 3 2 1 Type of Apple Granny Smith McIntosh Gala Golden Delicious Red Delicious Average number of seeds 2 4 7.5 3.5 1.5 Average Number of Seeds Bar Chart 8 7 6 5 4 3 2 1 Granny Smith McIntosh Gala Type of Apple 42 Golden Delicious Red Delicious Excel Graph for Average Number of Seeds Average Number of Seeds 8 7 Number of Seeds 6 5 4 3 Average number of seeds 2 1 0 McIntosh Granny Smith Macintosh Gala Golden Delicious Red Delicious Type of Apple Quantitative Graph Line Plot: Weight (in pounds) X X X X X X X X X X .45 .46 .47 .48 .49 .50 .51 .52 .53 .54 .55 .56 .57 .58 .59 .60 .61 .62 .63 .64 .65 .66 .67 .68 .69 .70 Weight of Apples (in pounds) 43 Classifying Virginia Products by Solid Figure Geometry Unit: Solid Figures Lesson 1 Standards of Learning: Math: 3.14 Social Studies: 3.6 Materials: - Virginia products and their general shapes (provide a picture or an example): Apple (sphere) - Bunch of grapes (cone) Tomato (sphere) - Hay bale (cylinder) Ear of corn (rectangular prism) - Peach (sphere) Cotton ball (sphere) - Watermelon (cylinder) Cucumber (cylinder) - Lumber (rectangular prism) Strawberry (cone) - Egg (sphere) Block of cheese (rectangular prism) - Cereal box (rectangular prism) Peanut (cylinder) - Sausage link (cylinder) Chicken nugget (sphere) - Loaf of bread (rectangular prism) Evergreen tree (square pyramid) - Pumpkin (sphere) Soybean (sphere) Large chart paper to be put on the ground and used as a grid, with sections titled: sphere, square pyramid, rectangular prism, cone, and cylinder with a picture beside the shape. Background Knowledge: Virginia produces many products that can be classified by general solid figures. Students can identify objects as a sphere, square pyramid, rectangular prism, cone, and cylinder using specific characteristics, including the number of angles, vertices, edges, faces, and general shape. Use the Agriculture Map of Virginia to discuss where these items are produced. This lesson provides concrete, tangible objects students can study and investigate to determine what solid figure the objects represent. 44 Procedure: 1. Discuss shapes and what the characteristics are of each solid figure. 2. Ask the children, one at a time, to sort the Virginia products by their solid figure. 3. Display a map of Virginia and talk about where the products are produced. Extension: Graph the number of products for each solid figure. 45 Classifying Virginia Products by Solid Figure Geometry Unit: Solid Figures Lesson 2 Standards of Learning: Math: 3.14 Social Studies: 3.6 Materials: - Virginia products and their general shapes (provide a picture or an example): Apple (sphere) - Bunch of grapes (cone) Tomato (sphere) - Hay bale (cylinder) Ear of corn (rectangular prism) - Peach (sphere) Cotton ball (sphere) - Watermelon (cylinder) Cucumber (cylinder) - Lumber (rectangular prism) Strawberry (cone) - Egg (sphere) Block of cheese (rectangular prism) - Cereal box (rectangular prism) Peanut (cylinder) - Sausage link (cylinder) Chicken nugget (sphere) - Loaf of bread (rectangular prism) Evergreen tree (square pyramid) - Pumpkin (sphere) Soybean (sphere) Large chart paper to be put on the ground and used as a grid, with sections titled: sphere, square pyramid, rectangular prism, cone, and cylinder with a picture beside the shape.

Extension: Graph the number of products for each solid figure. 47 48 4th Grade Number and Number Sense Students in 4th grade must identify decimal place values through the thousandths and determine their fraction equivalents. Computation and Estimation Decimals are used in sum and difference problems in this grade. Measurement Equivalent measurements for the U.S. Customary and metric units are explored by students for weight, length, and liquid volume. Geometry Points, lines, line segments, rays, and angles are identified by 4th graders. An understanding of parallelism and perpendicularity is also demonstrated. Probability and Statistics Predictions of outcomes are discussed with students, specifically the likelihood, or unlikelihood, of something happening. Patterns, Functions, and Algebra Students now create numerical and geometric patterns. The associative property is introduced for multiplication and addition. 49 Balancing Act Standards of Learning: Math: 4.3, 4.5, 4.16 Materials: One die Checkbook sheets (see p. 102) Green Deposit cards (see p. 103) Red Payment cards (see p. 104) Board game (see p. 105-106) Player pieces, such as cubes, small farm animal toys, different colored counters, etc. List of rules Scratch paper Background Knowledge: Living on a farm requires a constant knowledge of available funds. It costs money to feed animals and grow crops, but farmers can also make a profit. This activity allows students to practice adding and subtracting decimals, learn how to keep track of expenses, and understand what a farm costs. Procedure: 1. Create the board game on pages 105 and 106. 1. Print out the board game and glue it into a folder to create a folder game. 2. Print the deposit cards on green paper and the payment cards on red paper. 3. Print out multiple copies of the checkbook sheets for students to use while they play the game. 2. Explain the rules to the students: 1. Each player begins with $5,000. 50 2. Whoever’s birthday is next can go first. 3. Roll the die and move that many spaces. 4. If the box is green, draw and read a deposit card. Write the date, transaction description (deposit), and the deposit amount ($) in the boxes. Add the deposit amount to the starting amount and write the new balance. 5. If the box is red, read a payment card. Write the check number (starting with 1 and continuing for each check written), date, transaction description (payment), and the payment amount ($) in the boxes. Subtract the payment amount from the starting amount and write the new balance. Check Number Date Example 1/1/11 Transaction Description Deposit Example 1/11/11 Payment Payment Amount $350.11 Deposit Amount $45.29 Account Balance $5,045.29 $4,695.18 6. Continue these steps according to the color of the box you move to. Make sure to use the correct account balance when adding and subtracting. The balance will change with every move you make. Use scratch paper to help you solve the mathematics problems correctly. 7. Follow the boxes to the finish line. If you land on a box with special instructions, make sure to follow them. 3. Allow the students to play the game and practice their addition and subtraction skills with decimals. Extension: Ask students to write a story about themselves as a farmer, relating to the game in terms of the cost to run a farm. 51 Balancing Act Game Instructions: 1. 2. 3. 4.

Virginia farmers help provide consumers with necessary groceries including dairy, meat, and produce items. But how do crops and other commodities reach families, schools, and grocers? Consumers can buy food items at a grocery store or a farmer’s market. Some food has to go through different processes in order to be consumed. There are many steps for getting farm items to people. Procedure: 1. Discuss with students what happens to food before it gets to them. Use the following information to help them understand food does not appear out of nowhere, and there are steps food must go through in order to be eaten. a. Tysons has several processing plants in the state of Virginia for chickens and other poultry products. b. Cows are milked and their milk is collected into large tanks. The milk truck comes approximately every day to pump the milk out of the tanks into the tanker truck. The milk is then taken to a dairy 53 2. 3. 4. 5. processing plant to be cleaned, pasteurized, and bottled. c. Farms can provide eggs for egg packaging companies. The eggs are refrigerated in order to keep them fresh for the necessary period of time until they reach their destination. d. Corn can be taken to a grain elevator where it is kept until it is needed. Sometimes farmers wait to sell the grain until the prices increase, or when there is a greater need. Talk about where food goes after it has been cleaned and processed. Food items arrive in grocery stores, schools, farmers markets, and food banks. Food can travel many miles before it reaches a table to be eaten. Ask students to use the “From Farm to Food” map and the key to determine the answers to the questions asked on the worksheet. a. If this is the first time the students have measured distance on a map and converted the inches into miles, please demonstrate how to do so. The students need to find the two points of interest in the question, measure the distance between, and count by 4’s to determine the number of miles. Students should use quarter and half inches to get as exact of an answer as possible. Then hold a discussion about how food traveled when our nation first began, and how it travels today. Determine what impact those differences had on farmers and consumers. Explain how, in the 20th century, the United States moved from an agricultural society to a more industrial and urban country. Describe the events that led to this and the impact it has had on our nation. Extension: Take a field trip to a milk processing plant to learn more about how milk goes from the cow to a gallon in the store. Visit a local farmer’s market to investigate the fresh, Virginia products people can buy locally. 54 Natural Angles Standards of Learning: Math: 4.10 Materials: Picture of a flowering tree (see p. 107) Ruler Protractor Different colored pencils to differentiate the labels: o Red: points o Orange: lines o Yellow: line segments o Green: rays o Blue: angles o Purple: perpendicular lines o Brown: intersecting lines o Black: parallel lines Background Knowledge: Lines, angles, and points make up objects. Nature can be used to discover geometry by completing a “Geometry Search.” Some farmers grow flowering trees that produce fruit, such as apples. These trees are filled with intersecting lines, angles, points, and other geometric representations. Procedure: 1. Describe and illustrate to the students points, lines, line segments, rays, and angles. a. A point looks like a dot. b. Lines extend in both directions forever. c. Line segments begin and end with points. d. Rays have one end point and extend to infinity. 55 e. Angles are two rays that share the same endpoint/vertex. 2. Parallel lines never intersect, perpendicular lines intersect and form a right angle, and intersecting lines intersect at least once creating any type of angle. 3. Give each student a picture of a flowering tree (see p. 107). 4. Ask them to use the key described above to draw on the picture the geometric representations they see. Encourage them to label the representations appropriately underneath the image. Extension: Invite students to go outside and take pictures of natural geometric representations they see. 56 Pollination Probability Standards of Learning: Math: 4.13 Social Studies: VS.1, VS.4, VS. 6 English 4.7 Materials: Farmer George Plants a Nation by Peggy Thomas Name cards (see p. 112-114) o To make it easier to identify the students, punch two holes at the top of the name card and tie a piece of yarn so that the children can wear it around their necks. Quarters Recording sheets (see p. 115-116) Background Knowledge: When settlers came to America, they brought foreign items with them, including apple trees, peach trees, and watermelon. Not only did they bring produce to plant, worms and honeybees were also transported across the Atlantic. Without earthworms or bees, the nonnative plants would not have been able to survive. Virginia colonists grew squash, beans, watermelon, pumpkins, apples, and peaches, with the help of pollinating bees and wiggling earthworms. Through this lesson, students learn about probability, pollination, and historic agriculture. Procedure: 1. Read to the students Farmer George Plants a Nation by Peggy Thomas. Describe the agricultural history of Virginia. Point out similarities and differences between the past and present farming practices. Discuss the agricultural advancements Washington made and the importance of his life to this nation. 2. Describe the game to the students: a. Some people will be farmers. Everyone else will be bees. The bees will simulate pollination by flipping coins. If it is heads, the farmer’s crop is pollinated by that bee. If the coin lands on tails, the bee did not pollinate the 57 crop. The bees will have 3 minutes to visit the farms. At each stop, the bee will flip the coin and record which side it landed on. No matter what side landed facing up, the bee and farmer need to record the information on their sheets of paper. 3. Tell students they will discover pollination through probability. Assign 1 student as the farmer of the following crops grown in colonial Virginia: squash, pumpkins, beans, watermelon, apples, and peaches (total of 5 students). Give them their name cards to identify their crops. 4. Ask the farmers to stand throughout the room and give them the “Farmer’s Record” sheet (p. 115). Instruct them to keep track of the number of bees that visit their farm, and if the bees pollinated their crops or not. If a bee’s coin lands on heads, your crop was pollinated. If a bee’s coin lands on tails, your crop was not pollinated. Check the appropriate box on your sheet for each bee that visits you and your farm. 5. Give the rest of the children a quarter and tell them they are bees that will pollinate the farmer’s plants. Distribute the name cards so students remember their roles. 6. Hand out the “Bee Record” sheet to the students acting as bees (p. 116). Instruct them to go to a farmer, flip their quarter, and record if it landed on heads or tails. Ask them to tell the farmer which side of the coin landed facing up. DO NOT move on to the next farmer until you know your flip was recorded. 7. Allow students to “pollinate” the farms for 3 minutes. They must be careful to keep track of each coin flip! 8. Once the 3 minutes is up, ask the students to find the probability of pollination. a. Bees: Take the number of pollinated crops and divide that number by total number of trips to the farmers. Multiply this number by 100 to get the percentage. b. Farmers: Take the number of pollinated crops and divide that number by the total number of bees that visited your farm. Multiply this number by 100 to get the percentage. 9. Complete several more times so students have an opportunity to play all of the parts. 10. Then, discuss how, in the long run, your probability with be about 50% pollination. a. Visit http://pbskids.org/cyberchase/games/probability/cointoss.html to show students that, as you flip more coins, your probability gets close to 50/50. Extension: Have students write a story about their life in colonial Virginia, describing the hardships colonists faced, especially during the initial days and the food shortage. If you have old, colonial-styled clothing, allow farmers to wear them. 58 59 60 5th Grade Number and Number Sense An understanding of prime and composite numbers develops in 5th grade. Computation and Estimation Multi-step problems with whole numbers, decimals, and fractions are expected of students. Children also use the order of operations. Measurement Perimeter, area, and volume are solved by students. The parts of a circle are introduced, including: diameter, radius, chord, and circumference. Geometry Fifth grade students classify angles, triangles, and plane figures. Probability and Statistics Sample spaces are used by fifth graders to make predictions. Stemand-leaf plots and line graphs are created. Also, vocabulary such as mean, median, mode, and range is gained. Patterns, Functions, and Algebra Variables are presented to children in one-step linear equations. The distributive property of multiplication over addition is also investigated. 61 Flowering Factorization Standards of Learning: Math: 5.3 Science: 5.5 Materials: Construction paper of every color White squares Brown yarn cut into 2 inch lengths or craft sticks Markers Scissors Tape or glue Practice worksheet (see p. 117-118) Background Knowledge: Plants use roots to obtain essential nutrients from soil. Without the thin stringy fibers, flowers and crops would not survive. Farmers rely on healthy soil and strong roots to keep their crops alive until they are ready to harvest. Roots begin forming during germination and continue to grow while the plant grows. This activity can teach students the parts of the plant and the importance of roots while learning prime factorization. Factors of a multiple can be broken down into only prime numbers. Students get a visual representation of how a number can be divided into multiplication fact families, and eventually only prime factors, using roots shooting from the stem of a flower. Procedure: 1. Discuss with students how to complete prime factorization. Explain that prime numbers can be multiplied together to make composite numbers. 62 Prime factorization breaks down a composite number until you reach only the prime factors that make it composite (18 = 2 X 3 X 3). 2. Use the practice worksheet (p. 117-118) to review prime factorization with your students. Make sure they understand that once a factor cannot be divided into two factors except 1 and itself, it is a prime number. 3. Remind the students to circle the prime numbers in the factorization trees so they can determine the prime factorization for the composite numbers they are practicing with. 4. After everyone has demonstrated a clear understanding of prime factorization, and their “trees” have been approved, ask them to choose one composite number to use for their Flowering Factorization activity. 5. Provide all of the supplies listed above. 6. Ask the students to cut out the center of a flower and write their composite number on it. Give them time to make their flower petals, stem, and leaves. 7. Once everyone has made their flowers, have the students write on white squares of construction paper the factorization of their composite number. Make sure the students include all of the steps, and not just the prime numbers. They need to demonstrate how they reached the prime numbers. 8. Ask the students to attach the factors appropriately, matching the practice they completed on the scratch paper. 9. On the prime numbers, draw a worm, bee, ant, or other garden critter to indicate the final factors of the prime factorization. 10. Hang up the flowers around the room. Extension: Smaller versions of this activity can be done using tooth picks. You can assign certain characteristics of composite number and students must provide an example, such as: “This composite number has 2 prime numbers (21).” Or, “Show me 3 different ways you can begin to find the prime numbers for the number 36 (starting factors: 2x18, 3x12, or 6x6).” Students could also complete this activity using root vegetables. Discuss the structure of a plant, specifically the cells. 63 Buzzing with Math Facts Standards of Learning: Math: 5.4, 5.18 Science: 5.5 Materials: Honeycomb Interactive Bulletin Board Lesson: “Buzzing with Math Facts” (see p. 119-121) o Bees o Equals signs o Honeycombs A bee book such as Hooray for Beekeeping by Bobbie Kalman or The Honeybee Man by Lela Nargi Background Knowledge: Bees create hives to store their honey. The combs bees build have six sides, and are shaped like regular hexagons. Honey and pollen are stored in the combs, and the queen bee also lays eggs in them. Farmers use bees for their honey and their pollinating abilities. Fruits and vegetables, such as apples, watermelons, blueberries, and cucumbers, would not grow without the help of bees. For this activity, honeycombs are used to practice determining factors for a number. By creating rows of combs, students can determine which factors of a multiple are missing. Students will need to determine, out of a few choices, which honeycombs (with numbers on them) belong to a particular bee. There will also be some honeycombs already posted, and the students will have to determine the missing factor multiple. Procedure: 1. Print hexagons on yellow paper and cut them out. 2. Laminate the hexagons. 3. Set up the bulletin board to practice factors of multiples. 64 a. Depending on what skills need to be practiced, the numbers can range from single, double, or triple digit multiples. 4. Read a bee book to the students and discuss the structure of a bee hive. 5. Explain the bulletin board: a. The bees represent a multiplication fact. The product is written on the wing. b. Each honeycomb represents a factor. For example, 2 and 6 are factors of 12. The numbers 2 and 6 are written on the honeycomb, and the number 12 is written on the bee. An equals sign (=) illustrates the equality of both sides of the number sentence: 2 x 6 = 12 (see the top example in the picture). i. Even though there are not multiplication signs on the board, please remind students that the honeycombs are multiplied together to get the number on the bee’s wing. If students are still confused, post multiplication symbols on the honeycombs. c. If there is a question mark (?) on a honeycomb or bee, the students must determine the missing number. This introduces children to variables and linear equations. It is up to the students to use their reasoning and multiplication knowledge to determine the factor that is missing. i. Example in picture: 3 x ? x 2 = 42 ? =7 d. If there is a ? after the = sign, the product of the multiple is the unknown. In other words, the students must solve the multiplication problem to determine the product. i. 4 x 6 x 1 x 8 = ? = 192 e. Give students a product and have them determine the multiples. f. Have students make their own equation with 1 variable (1 missing factor). 6. Have students create their own multiplication problem with 3 or more factors. Extension: The students can have a friendly competition by splitting the class into groups and asking them to work cooperatively and quickly to see which group can find the correct factors the fastest. 65 Quilt Classifying Standards of Learning: Math: 5.11, 5.12 History: USI.8 English: 5.8, 5.9 Materials: Quilts Construction paper of every color Large paper grocery bags o Each child needs one panel of the bag (sides with the handles on them). Either cut these prior to the lesson, or pair students up with a grocery bag and ask them to do it. Rulers Protractors Glue Cotton plants or bolls Cotton balls Scissors Sample quilt template (see p. 122) Background Knowledge: Some farmers in Virginia grow cotton. This crop is ranked 16th in cash receipts for the state of Virginia, bringing in $36.3 million. Sixty thousand acres of Virginia land grow cotton. Cotton is harvested and sent to a cotton gin to separate the seeds from the cotton. The bales of cotton leave the gin and arrive at a textile mill where the cotton is cleaned, stretched, rolled, and dyed. Cotton has been an important agricultural commodity since the United States was founded. The cotton gin was created by Eli Whitney, leading to incredible growth in production and life for Americans. 66 Procedure: 1. Discuss with the students about cotton and its importance in Virginia. Read Eli Whitney and the Cotton Gin by Jessica Gunderson and talk about the significance of this invention. 2. Pass around a cotton plant or boll and cotton ball and discuss the differences between the two. Ask students about their clothes and how the cotton cloth feels in comparison to the cotton examples passed around. 3. Bring in several quilts and lay them out on the floor. The quilts can be intricate or simple, but there should be enough angles and shapes, especially triangles, for students to measure. 4. Assign students to different blankets. Pass out rulers and protractors 5. Ask students to find an acute angle (less than 90˚) on their blanket. Ask them to measure it and check other members of their groups to make sure everyone has chosen an appropriate angle. 6. Ask students to find an obtuse angle (greater than 90˚). Ask them to measure it and check other members of their groups to make sure everyone has chosen an appropriate angle. 7. Ask students to find an equilateral triangle (all sides are equal). Ask them to measure it and check other members of their groups to make sure everyone has chosen an appropriate triangle. 8. Ask students to find an isosceles triangle (two sides are equal). Ask them to measure it and check other members of their groups to make sure everyone has chosen an appropriate triangle. 9. Discuss with students patterns found in the quilts, shapes that be classified, and the texture of the fabrics. 10. Provide students with a section of a brown paper grocery bag to use as a base for their quilt. Allow them to use construction paper, glue, scissors, protractors, and rulers to create their own paper quilt. Make sure they understand they must include a combination of acute, right, obtuse, and straight angles as well as right, acute, obtuse, equilateral, and scalene triangles. Their quilts can include patterns or a scene of some sort. a. Students should measure and draw their shapes using a protractor and ruler. After cutting the shapes out, students should glue them on to the brown bag base in their chosen design. 11. Display the quilts around the classroom. 67 Extension: Students could research ways to harvest cotton and quilting techniques during the Civil War. Research about how cotton was used and the products made with this crop could also be completed. Then, students can research harvesting methods cotton farmers use and how people make quilts today. A Venn diagram can be created using the information students find. Also, during the Civil War, quilt patterns communicated messages amongst slaves. Students could research different symbols used in the quilts and what the symbols meant. Then they could incorporate the symbols into their quilts and write a journal entry from the perspective of a slave searching for freedom. Material for quilts used to come from sack bags, old clothing, and scraps of cloth. Women would gather together and have quilting bees. Certain areas of the country used this as a way to build community values and relationships. Quilts brought people together, especially during the Great Depression. Ask students to write a diary entry as if they were growing up during the Depression. Many farmers also struggled with their crops, so students could take on the role of quilter or farmer. Examples of Quilt Patterns 68 Coordinating Crops Lesson 1 in 5th Grade Probability Unit Standards of Learning: Math: 6.11 Social Studies: 3.5 Materials: Large grid on chart or butcher paper with letters as the x-axis and numbers as the y-axis Items that can be placed on various points: o Cotton o Apple o Tomato o Small cereal box o Egg o Spool of wool/yarn o Seed packet Background Knowledge: Gardeners and farmers plant their fields by plotting their seeds in order to provide enough space for the plants to grow. A grid can be used to illustrate the exact location of the seeds. In order to understand how a grid can be used, students must practice naming coordinates on the grid. Farmers use Global Position System (GPS) and Geographic Information System (GIS) to accurately determine positions using technology. The technology is used for farm planning and mapping, soil sampling, and crop scouting. Farmers are also assisted by these systems when visibility is hindered while maneuvering their farm equipment. For more information about these technology systems, please visit http://www.gps.gov/applications/agriculture. 69 By placing tangible items on points of a coordinate plane, students can practice naming coordinates and prepare to use that knowledge in future activities. Procedure: 1. Using large chart or butcher paper, create an enlarged version of a coordinate plane. Label the x-axis with letters, and the y-axis with numbers. 2. Lay the grid out and gather the students around it. Put several items on various points of the coordinate plane. 3. Name one item. Describe how to name the coordinates for the item. Tell students that you state the x-axis (letter) then the y-axis (number). Write the example on the board so students can see it. 4. Ask students to name the coordinates of other objects on the coordinate plane. 5. Remove the items. Provide the coordinates for the objects and ask the students to put the objects in the correct place. Extension: Use the activity “Herding Cattle” to practice naming coordinates and teach probability. 70 Herding Cattle Lesson 2 in 5th Grade Probability Unit Standards of Learning: Math: 3.17, 5.14, 5.15, 5.16 *This lesson follows “Coordinating Crops” Materials: Game instructions (p. 123) Game Board (1 per student, p. 124) Cow game pieces (4 sets per page, but only 1 set per student, p. 125) Dividers to separate players (folder, binder, etc.) Scrap pieces of paper (1 per student) Dry erase markers (1 per student) Background Knowledge: When farmers raise cattle, they allow them to graze in their fields. However, over time, the grass will be eaten and the ground trampled on by the cows’ paths. Cattle will often pull up new grass, including the roots, leaving the ground barren, if allowed to graze too long in one area. In order to preserve their land, farmers herd their cattle from paddock to paddock. The length of time the cows are kept in one area depends on the amount of land and the number of cattle. Farmers use different techniques to herd cattle but no matter what way they do it, all of the cattle must be accounted for. In this activity, students must guess where calves, cows, and bulls are on their opponent’s game board. Calves fit on 1 point, cows on 2 points, and the bull on 3 points. Cows go their own ways sometimes and ignore the famers’ instructions. It can take farmers several tries to round up all of the cattle. Thus, the cows and bulls cannot be “herded” with just one point guessed correctly. It might take the farmer several calls to get them to move, and it will take the players several correct points to “herd” the cows. 71 Probability can be determined by using a sample space. The probability of guessing the correct coordinate on the first try can be determined by finding the number of points the game pieces fit on, divided by the number of total points possible. The actual percentage of people guessing the correct answer on the first try is determined by the following equation: (number of people guessing a correct coordinate on the first try ÷ total number of people playing) x 100. This lesson teaches students how to determine sample spaces while gaining an appreciation for cattle farmers. Procedure: 1. Complete the “Coordinating Crops” lesson and review coordinate planes. 2. Pair off the students in the classroom. 3. Ask them to set up their games. Each student should have a coordinate plane, cow game pieces, a pencil, dry erase marker, and a scrap piece of paper. 4. Make sure a divider is placed between the two students so no one can see their opponent’s board. Tell the students to place the cattle on their coordinate planes. The calves fit on 1 point, the cows on 2 points, and the bulls on 3 points. None of the animals can go on the board diagonally and the animals cannot touch. 5. Ask the students to play the game by calling out coordinates. A cow is not herded until all of the coordinates it fits on are called by the opponent. Make sure the students use the scrap paper to keep tallies how many times it took them to guess a coordinate on their opponent’s board. The opponent must respond to the other player, notifying their classmate if the guessed point “hit” or “missed” a cow. 6. Tell students to use the dry erase markers to keep track of their guesses: a. Put an X on their board for their guesses they’ve made on their opponent’s board to keep track. b. Put a ● for the coordinates their opponent guesses correctly (i.e. the coordinates the cows are on). This way students know when cows on their boards have been “herded.” 7. Tell students to stop guessing once they’ve guessed a correct point. They should allow their opponent to continue guessing until he/she also guesses a correct point. 8. Once both players have made a “hit,” ask them to stop playing and wait for everyone in the class to have made a “hit” (guessed a coordinate correctly). They will continue playing in a moment. 72 9. Go around the room and ask the students to tell how many times it took them to guess a correct coordinate. Create a classroom line plot to organize everyone’s data. 1 2 3 4 5 6 7 8 9 10 11 12 13 10. Determine the most common number of tries students took to guess a correct coordinate (mode). 11. Make a stem-and-leaf plot using the number of tries it took the students to guess a used coordinate. Discuss the similarities and the differences between a line plot and a stem-and-leaf plot. a. High/low might be needed for the stem-and-leaf plot. b. What is important to remember when creating both types of plots? (spacing) 12. Ask the students to determine the number of possible coordinates on the game board (132). Then count how many coordinates are used by the game pieces (21). a. This creates a sample space for the students. Theoretically, the probability of guessing a cow’s coordinate on the first try is found by: Number of points used by the game pieces Number of possible points 21 ÷ 132 = 15.91% b. Using this sample space shows students that, after completing this experiment many times, the probability of guessing the correct coordinate on the first try will get closer to the probability found above. 13. Determine the number of people that guessed right on the first try (information can be found on the line plot). To find the empirical probability of guessing right on the first try: divide the number of people that did so by the total number of people. a. Empirical probability is based on direct observations or experiences. Thus, in order to find the empirical probability of this experiment, you must take the actual event divided by the total number events. Or, the actual number of people that guessed correctly on the first time, divided by the total number of people playing. 14. Then discuss with students the differences between the theoretical probability and the empirical probability. Ask questions such as: a. Why do you think the numbers are different? b. If we played this game every day and kept adding together our data, would the probability be closer to the theoretical probability or would it move further away? 73 15. Allow the students to continue playing the game. Repeat the experiment multiple times to show students how varied your results can be when using a small sample space and how important it is for researchers to use good data and appropriately sized sample spaces. Extension: Complete the experiment over several days and add together all of the results to create an expanded sample space. This can provide a concrete example of how empirical probabilities can get closer to theoretical probabilities if done over time. If you want to discuss predicting the number of people that would guess it right on the first time, you can have students complete the following formula: theoretical probability X # of people playing the game = the # of people that would guess right on the 1st time Students can play by themselves using a numbered die and a lettered die. 74 Virginia Standards of Learning 75 As of 2011, the following Virginia Standards of Learning are addressed in this book.

It takes time to gather all of the cows and move them. For this game, you must guess the location (coordinates) of the cows. Once you’ve guessed all of the points, that cow has joined the herd and moved to the new paddock. Game Instructions: 1. Put the divider between you and your partner. Grab a scrap sheet of paper and pencil. 2. Place your cows on your game board. The calves go on 1 point, the heifers go on 2 points, and the bull goes on 3 points. None of the animals can go on the board diagonally and the animals cannot touch. 3. Take turns guessing the coordinates your partner placed his/her cows. Make sure you say the letter then the number (A1, B10, etc). Keep track of the number of guesses you’re making. a. Use the dry erase markers to keep track of your guesses: i. Put an X on their board for their guesses they’ve made on their opponent’s board to keep track. ii. Put a ● for the coordinates their opponent guesses correctly (i.e. the coordinates the cows are on). This way students know when cows on their boards have been “herded.” 4. Once you’ve guessed correctly for the first time, stop guessing and tally how many times it took you. Allow your partner to guess until he/she has guessed correctly. 5. Participate in the classroom discussion about calculating probability. 6. Finish the game and herd all of your partner’s cows into the new paddock! 123 Herding Cattle Game Board 124 Herding Cattle 4 sets of game pieces 125
