Fact Family Fun

Do you know what a fact family is? A fact family is a bunch of numbers that all work together…

Here is an example.

In every fact family there are three numbers.

When you have a fact family you have to use the same numbers all the time….

You can add the numbers…. Or you can subtract the numbers…
