Reteach: Division & Multiples

Multiplication and division are inverse operations. This means that one can be “undone” by the other. Because they are related in this way, you can use division to decide whether or not one number is a multiple of another.

To decide whether 18 is a multiple of 5, determine whether or not 5 can divide evenly into 18.

18 divided by 5

Since there is a remainder of 3, 5 does not divide evenly into 18. So,18 is not a multiple of 5.

To decide whether 36 is a multiple of 9, determine whether or not 9 can divide evenly into 36.

36 divided by 9

Since there is no remainder, 9 does divide evenly into 36. So, 36 is a multiple of 9.

Reteach: Guided Practice

Multiples are skip-counting numbers, or “count by” numbers. To find the multiples of five, we count by 5s. To find the multiples of ten, we count by 10s. To find the multiples of twelve, we count by 12s, and so on.

1. Use division to determine if 21 is a multiple of 3.
21 divided by 3 Does 3 divide evenly into 21, with no remainder?   Yes   

Is 21 a multiple of 3?   Yes   
2. Use division to determine if 19 is a multiple of 6.
19 divided by 6 Does 6 divide evenly into 19, with no remainder?   No   

Is 19 a multiple of 6?  No
