Fact Family Worksheet Generator

A fact family is three related numbers that make four equations — for 2, 3, 5 that's 2 + 3 = 5, 3 + 2 = 5, 5 − 3 = 2, 5 − 2 = 3. Kids see the triangle and write all four facts underneath. Pick addition/subtraction (Grades 1–2) or multiplication/division (Grade 3), and print with an optional answer key.
