Fact Families and Number Bonds

Front

What is the commutative property in addition?

Back

The commutative property states that you can add numbers in any order. For example, 3 + 5 is the same as 5 + 3.

What is a fact family?

Back

A fact family is a group of related addition and subtraction (or multiplication and division) facts that use the same numbers. For example, the numbers 10, 4, and 14 form a fact family: 10 + 4 = 14, 14 - 10 = 4, 4 + 10 = 14, and 14 - 4 = 10.

Front

How do you find a related addition fact from a subtraction fact?

Back

To find a related addition fact from a subtraction fact, you can rearrange the numbers. For example, from the fact 12 - 4 = 8, the related addition fact is 8 + 4 = 12.

What is an addend?

Back

An addend is a number that is added to another number in an addition operation. For example, in the equation 3 + 5 = 8, both 3 and 5 are addends.

Front

What is a number bond?

Back

A number bond is a visual representation that shows the relationship between a whole number and its parts. For example, the number bond for 10 can show 7 and 3 as its parts.

Front

How can you represent the fact family of 10, 4, and 14 using equations?

Back

The fact family can be represented with the following equations: 10 + 4 = 14, 4 + 10 = 14, 14 - 10 = 4, and 14 - 4 = 10.

Front

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

Back

In a fact family, addition and subtraction are inverse operations. The sum can be used to find the difference, and vice versa.

Front

Can you give an example of a number bond for the number 12?

Back

An example of a number bond for 12 could be 5 and 7, showing that 5 + 7 = 12.

Front

What is the difference between a fact family and a number bond?

Back

A fact family consists of related addition and subtraction facts using the same numbers, while a number bond visually represents the relationship between a whole number and its parts.

Front

How do you create a fact family from three numbers?

Back

To create a fact family from three numbers, write all possible addition and subtraction equations that can be formed using those numbers.
