Fact Family Worksheet

A fact family is three numbers that belong together, and the four addition and subtraction facts they make. Once a second grader sees that 24, 38 and 62 are one family, she stops treating 62 − 38 as a brand-new problem and starts reading it off the family she already knows. This fact family worksheet builds that habit with number bonds: a whole on top, its two parts underneath, and room to write all four facts the trio can make.

Each of the three boxes on this page holds one number bond and four answer boxes. Every number is already given, so the child is not hunting for a missing addend — the work is seeing that the same three numbers rearrange into two addition facts and two subtraction facts, and writing each answer in its box. The numbers run to 62, 72 and 46 and two of the three families regroup, which is what makes this 2nd grade fact families practice rather than a first-grade review. Use it for morning work, in a math center, as homework, or as a quick check before a unit test. Page two is a complete answer key.

What’s Included

• 1 print-ready PDF worksheet
• Answer key
• 3 number bonds with 12 facts to complete

Three reasons this page earns its place in a second-grade math block. First, the number bond shows the part-part-whole relationship as a picture, so a child who is still counting on fingers has something to look at while the idea settles. Second, writing the commuted pair (24 + 38 and 38 + 24) right next to each other makes the commutative property visible instead of abstract. Third, the two subtraction facts sit in the same box as the addition facts, which is exactly how a child learns to use a known sum to solve a difference — the heart of subtraction fluency within 100. A fact family worksheet like this one also gives you a fast, honest read on which children still need counters.

Away from the page, build the same families with objects. Give your child a handful of counters, split the pile two ways, and say all four facts out loud before writing anything. Draw a bond on a whiteboard, cover one circle with your thumb, and ask what is hiding. Roll two dice, add them, and name the family the three numbers make. Play a quick round of “I say the whole, you say the parts” in the car. And keep a family your child finds tricky on the fridge for a week — repetition in small doses beats one long drill.
