Exploring Fact Families Flashcard

Front

What is a fact family in mathematics?

Back

A fact family is a group of related addition and subtraction or multiplication and division facts that use the same numbers.

Front

Create an addition fact for the numbers 3, 8, and 11.

Back

3 + 8 = 11 and 8 + 3 = 11.

Front

Create a subtraction fact for the numbers 14, 5, and 9.

Back

14 - 5 = 9 and 9 + 5 = 14.

Front

What is the relationship between addition and subtraction in a fact family?

Back

Addition and subtraction are inverse operations; knowing one allows you to find the other.

Front

Create an addition fact for the numbers 4, 7, and 11.

Back

4 + 7 = 11 and 7 + 4 = 11.

Front

Which equation is NOT part of the fact family for 9 + 6 = 15?

Back

9 + 7 = 16 is not part of the fact family.

Front

What are the components of a fact family for the numbers 9, 6, and 15?

Back

The components are: 9 + 6 = 15, 6 + 9 = 15, 15 - 9 = 6, 15 - 6 = 9.

Front

How can you identify a fact family?

Back

A fact family can be identified by finding all the addition and subtraction equations that can be formed with the same set of numbers.

Front

What is the sum of 9 and 6?

Back

The sum of 9 and 6 is 15.

Front

What is the difference when subtracting 6 from 15?
