## Fact Families

**‘ Addition and Subtraction – Fact Families.’** A fact family is a group of three numbers that make four math facts. For example, the number 4, 6, and 10 make 4 math facts: 4+6=10, 6+4=10, 10-6=4, and 10-4=6. For addition/subtraction, the fact family has two addition sentences and two subtraction sentence with three numbers. The concept is foundational for both addition and subtraction. The worksheets use different variations to reinforce student’s understanding of the concept, while keeping them engaged and challenged.
