Exploring Multiples Module 2

Teacher Introduction Activity: *Students stand in a circle. *Students skip count by 3. *Go around the circle twice. 1. When we skip count by 3, what are the first numbers we said? 2. What do the numbers you said have in common? 3. Did we say the number 13? Why not?

Key Vocabulary A multiple of a number is the product when that number is multiplied by any other whole number.

Question #1 What are 3 multiples for the number 4? Discussion: 1. What numbers did you say? 2. How can you show that the numbers are multiples of 4? 3. Is the number 17 a multiple of 4? Why or why not?

Question #2 What are 3 multiples for the number 6? Discussion: 1. What numbers did you say? 2. How can you show that the numbers are multiples of 6? 3. Is the number 32 a multiple of 6? Why or why not?

Discussion Questions How does skip counting help you figure out the multiples of a number? How does knowing your math facts help you figure out the multiples of a number?

Exploring Multiples on a Hundred Chart Provide students with hundred charts. On your hundreds chart, shade in all of the multiples of 4 that are less than 50. Compare your charts with a partner, and see if you shade the same numbers. 1. What patterns do you notice? 2. Could you use that pattern to identify the multiples of 4 that are greater than 50? How would you do that?

Discussion Statements Determine whether each statement is true or false, and how you could prove your answer is correct. A. All multiples of 4 are even. B. All even numbers are multiples of 4. C. Some multiples of 4 are also multiples of 5. D. Some multiples of 5 are also multiples of 4.

Additional Exploration Use a second hundred chart. Choose another number and shade in all the multiples of that number on your hundreds chart. Write a statement about the multiples of your chosen number. Example: All of the multiples of 4 are even numbers.
