Spiral Review 8: OA Multiplication and Division Fact Families

Front

What is a multiplication fact family?

Back

A multiplication fact family consists of a set of related multiplication and division facts that use the same numbers. For example, the numbers 5, 7, and 35 form a fact family: 5 x 7 = 35, 7 x 5 = 35, 35 ÷ 5 = 7, and 35 ÷ 7 = 5.

How do you find the missing number in a division equation?

Back

To find the missing number in a division equation, you can use multiplication. For example, in the equation 20 ÷ ___ = 5, you can multiply 5 by the missing number to find that 20 = 5 x 4, so the missing number is 4.

Front

What is the relationship between multiplication and division?

Back

Multiplication and division are inverse operations. This means that if you know a multiplication fact, you can use it to find the corresponding division fact. For example, if 9 x 5 = 45, then 45 ÷ 9 = 5.

What is the result of 12 ÷ 2?

Back

The result of 12 ÷ 2 is 6.

Front

What multiplication fact can be used to solve 45 ÷ 9?

Back

The multiplication fact that can be used is 9 x 5 = 45.

Front

How do you determine which numbers belong to the same fact family?

Back

Numbers belong to the same fact family if they can be used to create related multiplication and division equations. For example, the numbers 5, 7, and 35 can create the equations: 5 x 7 = 35, 7 x 5 = 35, 35 ÷ 5 = 7, and 35 ÷ 7 = 5.

What is the answer to 21 ÷ 3?

Back

The answer to 21 ÷ 3 is 7.

Front

If 7 x 5 = 35, what is the corresponding division fact?

Back

The corresponding division fact is 35 ÷ 5 = 7.

Front

What is the missing number in the equation 20 ÷ ___ = 5?

Back

The missing number is 4.

What is a fact family diagram?

Back

A fact family diagram visually represents the relationships between the numbers in a fact family, showing how they connect through multiplication and division.
