Can you give an example of a fact family using the numbers 2, 3, and 5?

Back

Yes, the fact family for 2, 3, and 5 includes: 2 + 3 = 5, 3 + 2 = 5, 5 - 2 = 3, and 5 - 3 = 2.

What does it mean for a fact to not belong in a fact family?

Back

A fact does not belong in a fact family if it does not use the same numbers as the other facts or if it does not relate to the operations of addition and subtraction or multiplication and division involving those numbers.

Why is it important to understand fact families?

Back

Understanding fact families helps students recognize the relationships between numbers and operations, which is essential for solving mathematical problems and developing number sense.

What is an example of a fact that does not belong in the fact family of 4, 0, and 4?

Back

An example of a fact that does not belong is 4 - 4 = 0, as it does not relate to the other operations involving the numbers 4 and 0.

Front

How can you check if a fact belongs to a fact family?

Back

You can check if a fact belongs to a fact family by verifying that it uses the same numbers and follows the rules of addition and subtraction or multiplication and division.
