5th Grade Multiplication & Division 5.NBT.2.5 & 2.6

Front

What is multiplication?

Back

Multiplication is a mathematical operation that represents the repeated addition of a number. For example, 4 x 3 means adding 4 three times: 4 + 4 + 4 = 12.

Front

What is division?

Back

Division is a mathematical operation that represents the process of splitting a number into equal parts. For example, 12 ÷ 3 means splitting 12 into 3 equal parts, which equals 4.

Front

What is a dividend?

Back

A dividend is the number that is being divided in a division problem. For example, in 20 ÷ 4, 20 is the dividend.

Front

What is a divisor?

Back

A divisor is the number by which the dividend is divided. In the problem 20 ÷ 4, 4 is the divisor.

Front

What is a quotient?

Back

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

Front

What is a remainder?

Back

A remainder is the amount left over after division when the dividend cannot be evenly divided by the divisor. For example, in 22 ÷ 5, the quotient is 4 and the remainder is 2.

Front

How do you check your work in division?

Back

To check your work, you can use the formula: Divisor x Quotient + Remainder = Dividend.

Front

What is an area model in multiplication?

Back

An area model is a visual representation of multiplication that shows how two numbers can be broken down into parts to find the product. For example, 27 x 19 can be represented as a rectangle divided into smaller rectangles.

Front

What is the relationship between multiplication and division?

Back

Multiplication and division are inverse operations. This means that if you know one operation, you can use it to find the other. For example, if 4 x 5 = 20, then 20 ÷ 5 = 4.

Front

What does it mean to find the product?

Back

Finding the product means calculating the result of a multiplication problem. For example, the product of 6 and 7 is 42.
