## McGraw-Hill My Math Grade 3 Answer Key Chapter 5 Lesson 2 Division as Equal Sharing

**Math in My World**

Example 1

Nolan feeds 6 carrots equally to 3 rabbits. How many carrots does each rabbit get?

Draw one carrot at a time next to each rabbit until there are no more carrots.

Write a division sentence to represent the problem.

A division sentence is a number sentence that uses the operation of division.

____ carrots equally shared by ____ rabbits gives ____ carrots to each rabbit.

6 ÷ 3 = ____ There are ___ carrots for each rabbit.

You can think of division sentences in two ways.

Answer:

6 ÷ 3 = 2

6 carrots were shared equally by 3 rabbits. There are 2 carrots for each rabbit.

Explanation:

The division sentence is 6 ÷ 3 = 2

A division sentence is a number sentence that uses the operation of division.

6 carrots are equally shared by 3 rabbits giving 2 carrots to each rabbit.

6 ÷ 3 = 2.

There are 2 carrots for each rabbit.

Example 2

Fifteen scouts equally shared 3 tents. How many scouts are in each tent? Place one counter (scout) at a time next to each tent until all the counters are gone. Draw a sketch of your counters.

**Helpful Hint**

When you divide, you share an equal number all of the groups.

____ scouts ÷ ____ tents = ____ scouts in each tent

There will be ____ scouts in each tent.

Answer:

15 scouts ÷ 3 = 5 scouts in each tent.

There will be 5 scouts in each tent.

Explanation:

**Talk Math**

Explain what it means to share equally when dividing.

Answer:

By dividing the group of objects into equal parts then we will get equal shares. We need to divide it into equal parts and share them equally.

Explanation:

There are 10 chocolates that should be shared among 5 students. So how many chocolates will each student get?

10 ÷ 2 = 5

So each student gets 5 chocolates.
