Fact family: It is a set of four related multiplication and division facts that use the same three numbers.
For example: The fact family for 3, 8 and 24 is a set of four multiplication and division facts. Two are multiplication facts, whereas the other two are division facts.
3 | × | 8 | = | 24 |
8 | × | 3 | = | 24 |
24 | ÷ | 3 | = | 8 |
24 | ÷ | 8 | = | 3 |
