How do we do division?

How do we divide?

• Split the total into equal groups.

• One does not simply *DO* division.

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.

Multiple Choice

What is division?

• Division is the inverse operation of multiplication

• Division is not a real word

• Division means to fly

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

Use Multiplication

40 ÷ 10 = 4

because

4 x 10 = 40

Multiple Choice

How can we rewrite the division sentence 28 ÷ 4 = ?

• 4 x ? = 28

• 4 x 28 = ?

Multiple Choice

How can we rewrite the division sentence

30 ÷ 6 = ?

• ? x 6 = 30

• ? x 30 = 6

• 6 x 30 = ?

• 30 x 6 = ?

Remainder

Sometimes, when you divide, you will have a reminder.

A remainder is whatever is leftover after you split up your dividend evenly as much as possible.

You can give the remaining chicken nugget to Mr. Smallwood!

​If we divide 7 chicken nuggets between two people (7 ÷ 2), each person will get 3 and there will be a remainder of 1 chicken nugget.

Multiple Choice

Solve 10 ÷ 3

• 2 r. 4

• 3 r. 1

• 13

• 7

• You cannot solve 10 ÷ 3

30 ÷ 3

30 is a multiple of 3, so there will not be a remainder. Each group will get 10.

Is your dividend a multiple of the divider?

Quick Check

Will I Have a Remainder

Do you know your multiples?

26 ÷ 3

26 is not a multiple of 3, so there will be a remainder. Each group will get 8 (3 x 8 = 24) so there will be a remainder of 2.

Multiple Select

Select all of the expressions that will have a remainder.

• 20 ÷ 4

• 200 ÷ 10

• 7 ÷ 2

• 15 ÷ 4
