Welcome to the fact family worksheets page at Math-Drills.com! This page includes Fact family worksheets including addition and subtraction relationships, and multiplication and division relationships.

## Addition and Subtraction Fact Families

Once students understand the relationship between addition and subtraction, subtraction becomes less of a mystery, and they are able to complete more complex problems.

## Multiplication and Division Fact Families

Multiplication and division have an inverse relationship, so if a student knows that 9 × 8 = 72 then they should also know the answer to 72 ÷ 8. These fact family worksheets should help make those relationships very clear to students and perhaps help them to understand division a little better. The number 1 as a factor is only used in the fact families to 49 and 64 worksheets. After that, the factors include only 2 and up. For example, in the fact families to 100 worksheets, the factors will fall in a range of 2 to 10.
