What are Math Addition Fact Families? When you are trying to teach basic mathematics to children, you need to have a few tricks up your sleeves. One of the most creative methods for teaching addition and subtraction is the fact family. A fact family is a bunch of math facts which uses the same number.

The table below illustrates the fact family of the abovementioned numbers.

4 + 5 = 9  9  4 = 5 
4 + 5 = 9  9  5 = 4
