What’s A Fact Family?

The term fact family refers to a set of math equations or facts that are arrived at using an identical set of numbers. Fact family aims to show a link between the three involved numbers. In addition to this, there’s at a minimum of four math facts that should be created using them.

An example of a fact family relationship is found between the numbers 3, 5, and 8. This is because adding the first two numbers, 3 and 5, gives you 8.

3 + 5 = 8

Even after switching the first two numbers, the answer will still be identical.

5 + 3 = 8

Understanding one fact in family facts helps you figure out the three other facts.

Fact Family Cousins

Besides the direct relationship between these family members, the inverse relationship, which is subtraction, is a family cousin. This is because it’s related to addition despite being its opposite and only involves the three family members.

8 – 3 = 5

8 – 5 = 3

Where Can You Use Fact Families?

The primary goal of using fact families is to help your kids learn or reinforce their knowledge on the connection between subtraction and addition. As a result, this helps the children remember the basic facts of addition and subtraction, including fact families and number rainbows.

Why Are Fact Families Important

Fact families is essential as it helps children understand the basic notion that addition and subtraction are each other’s opposite. Likewise, division and multiplication in fact families serve the same purpose. Therefore, it becomes necessary for fact families as it helps them become more flexible in their understanding of numbers.

Advanced Fact Family Worksheets

This includes division and multiplication in addition to addition and subtraction, as your students will need to learn this as they move to higher grades. You can also get tablet games and apps to make fact family more exciting and fun.


Understanding the relationship between fact family members is vital in assisting kids in solving addition and subtraction questions with much ease. Therefore, it becomes necessary to teach them this, which in the long run will help them have an easier time understanding more complex computations and improve their numerical skills.
