Lesson Plan Pre-Service Teacher: Samantha Fummerton Date of Lesson: 12/4/2012 Lesson Title/Description: Problem Based Lesson Lesson # 1 of 1 Time Allotted for this Lesson: 50 Minutes Goals: Objectives: 4.MP.1 Make sense of problems and The students will demonstrate their ability to persevere in solving them make sense of a two-digit multiplication problem Multiplication by using compatible numbers, and persevere in Estimation solving it. Compatible Numbers Pre-Requisite Knowledge and/or Skills: The students are fourth graders and should have a concept of multiplication of two digit numbers. How I know the students have this: The third grade math standard: 3.NBT.3 Use place value understanding and properties of operations to perform multi-digit arithmetic addresses the previous knowledge that the students should have. Materials/Equipment/Supplies/Technology/Preparation: The students will be given The Problem: 53x24 and be asked to solve the multiplication problem, on their own sheet of paper, by using compatible numbers. The teacher must bring in a full jar of candy for anticipatory set. Students “Math Journals” that they keep in their desk to write down problems Procedure: Teacher Does………. Procedure: Students Do…….. Time Motivation/Hook: The teacher will bring in a jar of candy that is full of candy pieces. 10 They will ask the students to think about how many candies are in the jar and what their strategy for estimating will be. The students will each get about 30 seconds to look at the jar and decide what their guess will be. The student that guesses the closest to the number will win the contest. The winner will be revealed at the end of class Motivation/Hook: After the teacher brings in the jar of candy, the students have ten minutes to think of a good guessing strategy and make a guess at how many pieces of candy are in the jar. Each student will get about 30 seconds to look at the jar and decide their guess. After they make their guesses the teacher will reveal the winner of the contest at the end of class.

The students will write down all the One by one she will call on students examples their classmates give as the teacher to give their ideas about how to make does on the big white paper. a good estimate of how many candies The students will also give their own ideas were in the jar. when it is their turn. Some possible answers may be: Some possible answers are: “looking at how many are on the “looking at how many are on the bottom, and bottom, and seeing how many high seeing how many high and multiplying” and multiplying” “see how many are in a smaller area “see how many are in a smaller area and and multiplying by how many are in multiplying by how many are in the jar” the jar” As the students give their ideas the teacher will be copying them down onto the white piece of paper. Teaching Independent Application The teacher will post “The Problem” After the teacher posts “The Problem” on on the board for all students to see. the board, they will have 6 minutes to try and use a strategy to estimate the answer The teacher will instruct students to to the problem. copy the problem down into their math journal and to try and use any They will copy down the problem and their estimation strategy that we talked work into their “Math journals” and try to about to try and solve the problem. solve it using one of the estimation strategies that we had talked about Teacher will walk around and Possible Answers: monitor student progress Correct: Possible Answers: 50x20=1000 Correct: 53x(10+10)= (53x10)+(53x10)=1060 50x20=1000 Incorrect: 53x(10+10)= (53x10)+(53x10)=1060 53x24=1272 Incorrect: 53x24=1272 Teaching After the students have had adequate time to answer the problem, call on two students who you saw with a correct answer to come and show their answers and explain what strategy they used. Discuss their solution path as a class The teacher should show the “incorrect” path and talk about how when we see the word estimate it Independent Application After the students have had enough time to answer the problem the teacher will call on two of them to show their solution and solution path. As the teacher has a discussion the students will we taking notes in their Math Journals They will want to write down the word estimate and the definition that the teacher goes over The students will write down the words Western Oregon University, Division of Teacher Education, ED 434/534 Harrington (Modified from Cochran, 2011) Fall 2012 2 means to find compatible numbers compatible numbers with its definition to the problem to make it easier.

Closure Closure: 5 The teacher should conclude the After the discussion the teacher will ask each lesson with a wrap up about what students to turn to their neighbor and talk we went over about the one thing that they will remember from this lesson for the next day. Ask each student to turn to their neighbor and discuss one thing that they will remember for the next day. Meeting Varying Needs of Students: Scaffolding for students without pre-requisite knowledge: For students who do not have the pre requisite knowledge I will have them try this same problem and lesson, but with single digit numbers instead of double digit. Extension task: For students who finish early I would have a three digit problem for them to try. I would also ask them to help their neighbors if they are having trouble. Assessment 1. Evidence collected during/as a result of this lesson: As the teacher walks around, they are checking for the students progress. The teacher should be noticing how the students are solving the problem and should be checking their math journals for the solutions and they notes that they take. 2. Summative assessment is __3__ days after this lesson. Reflection: 1. Did all the students meet the objectives? How do you know? Western Oregon University, Division of Teacher Education, ED 434/534 Harrington (Modified from Cochran, 2011) Fall 2012 3 Reflection: 2. Describe any changes you made as you were teaching the lesson. Reflection: 3. What would you change about this lesson plan before you teach it again? Pay attention to situations where students either did not learn or already knew. Reflection: 4. How did the results of this lesson influence the way that you will teach in the future?
