Print by grade
-
1st grade Core grade
Each print is a different sheet with its own answer key. You don't need to sign up.
Fact families show 1st graders that addition and subtraction are connected: each house holds three numbers, and your child writes the two addition and two subtraction facts they make.
-
2nd grade
Second graders use fact families to lock in addition and subtraction facts within 20. Writing all four related equations from three roof numbers builds recall. If your child knows 7 + 6 = 13, the family hands them 13 − 6 for free.

3rd grade
In 3rd grade the houses switch to multiplication and division. Your child takes three numbers like 4, 6, and 24 and writes two multiplication and two division facts, learning that division is just a missing-factor problem.
