Activity Cards A Group of 10 and leftovers TOPIC: Early Place Value MATERIALS: Individual bags of Beans, Toothpicks, Washers, paperclips, buttons (anything students can count) – Put between 11 and 19 of an item in each bag TASK: Students dump the items in their bag and are asked to create A group of ten and investigate the number of “leftovers.” Van de Walle: PG 130 *adapted for Kindergarten Groups of 10 TOPIC: Early Place Value MATERIALS: Individual bags of Beans, Toothpicks, Washers, paperclips, buttons (anything students can count) TASK: Students dump the items in their bag and are asked to create groups of ten. They record the number of groups they can make and the “leftovers.” Van de Walle: PG 130 Estimating Groups of Tens & Ones TOPIC: Early Place Value MATERIALS: Toothpicks, paperclips, interlocking cubes TASK: Students estimate and then measure the length of various things. They count the measurement in ones and by groups of 10. Van de Walle: PG 132 Base-Ten Riddles TOPIC: Place Value MATERIALS: Base-ten materials Base-ten riddles on cards Present a group of students a baseten riddle and ask them to solve. TASK: Van de Walle: PG 134 Counting Rows of 10 TOPIC: Place Value MATERIALS: 10x10 array of dots on smartboard or overhead Introduce the concept of “20,” “30,” and so on. Uncover rows and parts of rows and have student identify the number of dots. TASK: Van de Walle: PG 134-135 Adding w/Rows of 10 TOPIC: Using Place Value to Add/Subtract Multiples of 10 MATERIALS: 10x10 array of dots on smartboard or overhead TASK: Model a number using the 10x10 grid (e.g. to model 43 uncover 4 tens and 3 ones). Once students name the number, uncover ten more dots and ask what number is shown. You could also cover ten dots at a time. Van de Walle: PG 135 *adapted Tens, Ones & Fingers TOPIC: Place Value MATERIALS: Students (and their fingers) TASK: Ask students for different ways to show 6 fingers, 8 fingers, etc. Then ask them, “how can we show 37 fingers?” Emphasize the number of sets of ten fingers and the “leftovers.” Van de Walle: PG 136-137 More and Less on the Hundreds Chart TOPIC: MATERIALS: TASK: Place Value & Adding/Subtracting Multiples of 10 A Blank Hundreds Chart Fill in one number for students and have them fill in it’s neighbors (left, right, below and above). Repeat for various numbers. Van de Walle: PG 139 Models with the Hundreds Chart A TOPIC: MATERIALS: TASK: Place Value & Adding/Subtracting Multiples of 10 A Hundreds Chart Place-Value Models Give students one or more numbers to make with the models and then find on the chart. Use groups of 2 or 3 numbers in the same row or column. Van de Walle: PG 139 Models with the Hundreds Chart B TOPIC: Place Value & Adding/Subtracting Multiples of 10 MATERIALS: A Hundreds Chart Place-Value Models TASK: Have students make ALL of the numbers in a specific row or column. How are the numbers in the row (or column) the same? How are the different? What happens at the end of each row? Van de Walle: PG 139 Models with the Hundreds Chart C TOPIC: MATERIALS: TASK: Place Value & Adding/Subtracting Multiples of 10 A Hundreds Chart Place-Value Models Indicate a number on the chart and have students model. What would you have to change to make each of its neighbors (the numbers to the left, right, above and below)? Van de Walle: PG 139 Modeling with Cubes TOPIC: Place Value (in numbers up to 19) MATERIALS: Baggies, Unifix or Interlocking cubes TASK: Students are given one rod of 10 interlocked cubes and 10 free cubes and are asked to model a number between 11 and 19. They then will record their results in ten-frames. Adapted from Illuminations http://illuminations.nctm.org/LessonDetail.aspx?ID=L548 Rolling Up to 100 TOPIC: Place Value MATERIALS: 2 dice, base-ten blocks TASK: Students take turns rolling a set of dice and get the number of blocks they roll from the “bank” each turn. They will exchange groups of 10 blocks for a rod of 10 as needed. The first student with 10 rods of 10 (100 blocks) wins! Rolling Down to 100 TOPIC: Place Value MATERIALS: 2 dice, base-ten blocks TASK: Students are given a 10 rods (100 blocks) and take turns rolling a set of dice. They give the number of blocks they roll to the “bank” each turn. They will exchange rods of 10 for blocks for individual blocks as needed. The first student to get rid of all of their blocks wins! Literature Connection TOPIC: Place Value TASK: There are many different books that offer rich connections to place value. Some include: - Earth Day Hooray - Can You Count to a Googol - More Thank One - Math Fables
