Division Review

Multiple Choice

How do we do division?

How do we divide?

• Split the total into equal groups.

• One does not simply *DO* division.

The Inverse Operation

Inverse operation means the opposite.

Division is like the opposite of multiplication.

Multiple Choice

I know that 4 x 10 = 40.

What division problem could I solve using this fact?

• 40 ÷ 10 = 4

• 4 ÷ 10 = 40

Sharing equally

In division, we split the total (dividend) into groups.

6 / 2 = 3

because 6 split into groups of 2 gives us a total of 3 groups.

Division Vocabulary

What is a dividend?

• A dividend is the number that is BEING DIVIDED

• Here is an example:

• 12 / 3 = 4

• The dividend in this equation is 12 because 12 is the number being divided.

Multiple Choice

What is a dividend?

• The number that is divided by

• The number that is being divided

• The answer

What is a divisor?

• A divisor is the number that is BEING DIVIDED BY

• Here is an example:

• 12 / 3 = 4

• The divisor in this equation is 3 because 3 is the number being divided by.

Multiple Choice

What is a divisor?

• The number being divided by

• The number that is being divided

• The answer

What is a quotient?

• A quotient is the ANSWER of a division problem

• Here is an example:

• 12 / 3 = 4

• The quotient in this equation is 4 because 4 is the answer.

Multiple Choice

What is a quotient? (using the process of elimination you should know the answer)

• The number being divided by

• The number that is being divided

• The answer

The 3 main parts of a division problem

• The total

• The number of groups

• The size of the groups

• The math terms for these three parts of the quotient (the answer), the dividend (the total, and the divisor (what you are dividing by).

What are our Steps

• Divide ( Does)

• Multiply (McDonalds)

• Subtract (Sell)

• Bring it on Down (Burgers)

Remainders!

How many were left after making equal groups.

In the example, you start with 27 total and are making groups of 4. You are able to make 6 equal groups of 4 which is a total of 24. There are 3 left that can't fit into a group of 4.

What are the different ways to answer a division problem that has a remainder?

• ignore the remainder

• the remainder is the answer

• Add 1 to the quotient
