Addition Fact Families

Addition and Subtraction Fact Families

You can turn around the numbers being added (the addends) and you will still have the same total.

If you know that 12+3= 15

then you know that 3+ 12= 15

Addition and subtraction are linked:

3+12=15

12+3=15

15-3=12

15-12=3

This is what we call a Fact Family.

Here is another;

24+6=30

6+24=30

30-24=6

30-6=24

It is important to notice that these subtraction facts begin with the largest number.

Now you could try making up some fact families of your own.
