A **fact family** is a group of related number sentences.

In a fact family, the number sentences are all made up

of the **same three numbers** arranged different ways.

A fact family has either addition and subtraction number

sentences or multiplication and division number sentences.

The given number sentence is a multiplication sentence.

There is one other multiplication sentence and two division sentences in the same fact family.

First, change the order of the factors to find the other multiplication sentence in the fact family.

3 × 6 = 18

Next, divide the product, 18, by both of the factors, 3 and 6, to find the division sentences in the fact family.

So, these number sentences are in the same fact family.

3 × 6 = 18 | | 6 × 3 = 18 |

18 ÷ 3 = 6 | | 18 ÷ 6 = 3 |
