Fact Family Worksheets
Updated October 2026 · 6 free printables
Three numbers, four facts. In these fact family houses the three numbers on the roof make two addition and two subtraction facts (or two multiplication and two division facts for third grade).
Fact families show kids that addition and subtraction are opposites, so one known fact unlocks three more.

Frequently asked questions
What is a fact family?
A group of facts made from the same three numbers. 3, 5 and 8 give 3 + 5 = 8, 5 + 3 = 8, 8 - 3 = 5 and 8 - 5 = 3.
Why do fact families matter?
They teach that subtraction undoes addition and division undoes multiplication, which helps kids check answers and solve missing-number problems.
Do doubles have fact families?
Yes, but a small one: 4, 4 and 8 only make 4 + 4 = 8 and 8 - 4 = 4. That is why these worksheets use two different parts.
