Unit 3: Multiplication and Division Review

Front

What is multiplication?

Back

Multiplication is a mathematical operation where a number is added to itself a certain number of times. For example, 3 multiplied by 4 (3 x 4) means adding 3 four times: 3 + 3 + 3 + 3 = 12.

What is division?

Back

Division is a mathematical operation where a number is split into equal parts. For example, 12 divided by 3 (12 ÷ 3) means splitting 12 into 3 equal groups, which gives 4.

Front

What is the area of a rectangle?

Back

The area of a rectangle is found by multiplying its length by its width. For example, if a rectangle is 5 cm long and 4 cm wide, its area is 5 cm x 4 cm = 20 cm².

Front

What is a group in multiplication?

Back

A group in multiplication refers to how many times a number is added together. For example, 4 groups of 3 means 3 + 3 + 3 + 3 = 12.

Front

What is the relationship between multiplication and division?

Back

Multiplication and division are inverse operations. This means that if you multiply a number and then divide by the same number, you will get back to the original number.

Front

How can you represent 4 + 4 + 4 using multiplication?

Back

You can represent it as 3 groups of 4, which is written as 3 x 4.

Front

What is a fact family in math?

Back

A fact family is a group of related addition and subtraction or multiplication and division facts that use the same numbers. For example, for the numbers 2, 3, and 6: 2 + 3 = 5, 3 + 2 = 5, 5 - 2 = 3, 5 - 3 = 2.

Front

What is a quotient?

Back

A quotient is the result of a division problem. For example, in 20 ÷ 4 = 5, the quotient is 5.
