Frequently Asked Questions
What is a fact family?
A fact family is a group of related addition and subtraction facts built from the same three numbers — for example, 3, 4, and 7 give you 3+4=7, 4+3=7, 7-3=4, and 7-4=3.
Why teach fact families instead of just addition facts?
Fact families show the real relationship between addition and subtraction, so kids see subtraction as "undoing" addition rather than as a completely separate skill to memorize.
What's a good starting number range?
Start with a largest addend of 5 or 10 for kindergarten and early first grade, and move up to 20 as facts become automatic.
