A fact family is the set of facts made from the same three numbers: 3 + 4 = 7, 4 + 3 = 7, 7 − 3 = 4 and 7 − 4 = 3. These sheets give the three numbers in a triangle and ask for all four facts: addition and subtraction families for 1st and 2nd grade, then multiplication and division families for 3rd. Every sheet has its answer key on the second page.

Fact families are how children learn that subtraction is addition turned around. A child who knows 8 + 6 = 14 and sees it as a family does not need to work out 14 − 6 separately.
Number bonds show the same idea with circles: one whole and its two parts. They usually come first, in kindergarten and early 1st grade, before the four facts are written out.
In 3rd grade the same idea returns with multiplication and division. The top of the triangle is now the product, and the two numbers at the bottom are the factors: 3, 4 and 12 give 3 × 4 = 12, 4 × 3 = 12, 12 ÷ 3 = 4 and 12 ÷ 4 = 3. Set A uses the easier tables, Set B the 6s to 9s, and the missing numbers sheet asks children to use a multiplication fact they know to answer a division fact.
