# Multiplication Flipbooks

Subjects:

Common Core, Math

Grades:

2, 3

Students will make a multiplication flipbook of strategies to use throughout the year to strengthen multiplication fluency and problem solving skills.

**STANDARDS**

CCSS.Math.Content.3.OA.A.1 Interpret products of whole numbers.

**OBJECTIVES**

Students will define product as the result of multiplication.

Students will interpret and explain products as the number of objects in groups of objects

**MATERIALS**

- Hotchalk.com Problem Solving Sheet for each student
- Flipbooks for each student (put together five pieces of paper and fold them over so that it creates a small book)
- Colored pencils/ drawing materials

**Product: Multiplication Warm up (10 Minutes)**

-Tell students that, in Math, we use words to describe specific things. (In addition we call two numbers that are added together a sum and in multiplication we call two numbers multiplied together a product)

-Remind students we have already started learning multiplication

-One way to practice multiplication is by skip counting. Tell students that you are going to play a game called “product”. You can play this game as a whole group or individual groups. Go through key fact families (3, 4, 6, 7, 8, 9, 11, 12). The first student starts counting. The next player continues counting. When a player gets to a multiple of that number, they call “product” (i.e. for the 3s times table, 1, 2, product, 4, 5, product). If a player forgets to say product or says is at the wrong time, he or she is out. Play a few rounds that hit important multiplication tables.

-For 2^{nd} grade you might want to hit the 3, 4, and 6 multiplication tables, and for 3^{rd} grade you might want to hit the 7 and 8 multiplication tables.

**Mini-Lesson: Multiplication Strategies (10 minutes)**

-Tell students that today we are going to practice different ways to show multiplication and we are going to make a flipbook that we can use as a mathematics resource throughout the year. Review 4 ways to show a multiplication problem:

- Show the problem in an array (a set that shows equal groups in rows and columns).
- Show the problem in a grid.
- Write the problem and use skip counting.
- Write the problem and use repeated addition.

(Model how to use each one by showing examples using multiplication problems 3×4 and 7×8. Then have students work in pairs to complete the representations for the problems 5×9 and 4×7)

-After students are finished, have them share and reflect:

- Which method was easiest for you?
- When might you use each method? (Solving a word problem, Solving a mental math problem, etc.)

**Make a Flipbook (20 minutes)**

Pass out flipbooks to each student. Provide each student with 5 problems that they must incorporate into their flipbook. Differentiate the student experience, and ensure student understanding by giving different problems and methods for each student to use.

** **

**Math Problem Solving (10 minutes)**

Once students have completed their flipbooks, tell them that they are going to practice using their flipbooks to problem solve. Post a multiplication story problem on the board and have students work independently for 2 minutes to solve the problem. After the students have finished the problem, have a few students share how they solved it. Identify which strategies each used. If students finish early, they should complete another problem.

**Multiplication Story Problems**

- Carla has 5 boxes of crayons. Each box holds 12 crayons. How many crayons does Carla have?
- There are 8 candies in one bag. How many candies are there in all if Marta packs 9 bags of candies?
- Rob decorated 6 cakes. He put 4 candles on each cake. How many candles did he use?
- 7 students go to the library. Each student has 7 books to return. How many books are returned?

Remind students that we will be using these various strategies throughout the school year so they should hold on to their flipbooks.
