Basic Arithmetic Operations and Fact Families

The video tutorial introduces the concept of fact families in mathematics, demonstrating how a set of three numbers can be used to create two addition and two subtraction problems. Through examples with different sets of numbers, the video illustrates how to form fact families and solve related math problems, helping students understand the relationships between addition and subtraction.

What is a fact family?

• A collection of unrelated numbers.

• A set of numbers that can only be multiplied.

• A group of numbers that can be added or subtracted to form different equations.

• A family of numbers that can only be divided.
