Certain numbers and facts are related or make up a fact “family” and there are only three numbers in each family. In the above fact family, the members are 5, 8, and 13. They are related because you can add two of the numbers together to get the third number. And the next fact would be 13 – 5 = 8.
What does fact family mean?
A fact family is a group of calculations that are created using the same three numbers. For example, here is a fact family that uses the numbers 2 , 4 and 6 .
What is a related number?
Related Numbers 1. Related Numbers tests you on addition, subtraction, multiplication and division. This is because 12 and 48 are related by dividing 48 by 12 to get the number in the middle. 19 is related to 114 in the SAME way (dividing 114 by 19 results in 6). The relationship is DIVIDE.

The Fact Family Relationships In the family 6, 4, and 10 they are related because you can add two of the numbers to get the last number. You can also switch the first two numbers, using the commutative property of addition, and still get the same answer.
In the case of addition and subtraction, you use three numbers and get four facts.
- For example, you can form a fact family using the three numbers 3, 10, and 13: 10 + 3 = 13, 3 + 10 = 13, 13 − 10 = 3, and 13 − 3 = 10.
- Addition facts − Here the sum of two of the three given numbers is the remaining third number.
