Number bonds/ Fact families

Learning intention:

To use fact families to help children learn the basic addition and subtraction facts.

What is a fact family?

A fact family is a group of math facts using the same numbers.  In the case of addition/subtraction, you use three numbers and get four facts.  For example, you can form a fact family using the three numbers 10, 2, and 12: 10 + 2 = 12, 2 + 10 = 12,  12 − 10 = 2, and 12 − 2 = 10.

Where do we use fact families?

We can use fact families to reinforce or learn the connection between addition and subtraction, and to help children memorize the basic addition & subtraction facts
