# Fact Family Worksheets

This topic is great to help students enhance their problem-solving ability and on-their-feet thinking. Fact families are a series of three numbers that share a relationship of some kind through math operations that inverses or counters of one another. Specifically, the operations of addition and subtraction or multiplication and division. This topic really helps students begin to see patterns emerge between different operations. As a result, you will find that students will begin to develop mental math skills at a much faster rate. We encourage teachers to approach using both horizontal and vertical orientations when working with this. These worksheets help students learn their math facts and the operations that take place.

### What Are Fact Families? There are many facts that we know, right? We know that the sun rises in the East, and we also know for a fact that all the planets revolve around the Sun. The statement that the Earth is curved is also a fact. When we combine all these facts together, they will form a small group. We have something very similar to that in mathematics as well. When you have a collection of addition and subtraction facts that are created by the same numbers, we call them fact families. This also holds true for numbers that have related multiplication and division facts. For example, 2,4 and 6: So, the fact family for addition and subtraction will be: 2 + 4 = 6 | 4 + 2 = 6 | 6 - 2 = 4 | 6 - 4 = 2. Suppose the numbers are 2,4, 8 : The equations for fact families will be: 2 x 4 = 8 | 4 x 2 = 8 | 8 ÷ 2 = 4 | 8 ÷ 4 = 2.

In math a fact family is a group of numbers that relate directly to each other on a base set of operations. In mathematics, if you find a series of three numbers appearing in four statements or facts, it is known as fact family. The numbers, in fact, families are identical in each of the four facts. You may also hear these referred to as number families.

There are two types of fact families. The first family is known as the addition and subtraction family. The second family is known as the multiplication and division family. These operators share an inverse relationship. This also goes to show us how these operations have a direct relationship with one another. When we start working with algebra and solving for unknown variables within an equation this skill is super valuable to remember. The concept of countering operations that are already present are what we are trying focus on here. When you take time to practice finding these values all on your own, you will find that your mental arithmetic skills will become greatly heightened.
