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. 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. 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.
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. 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.
