Division

This week we are going to divide numbers by sharing objects to work out the answer.

EG:

Think about:

How many do you have to begin with?   12 cubes

How many equal groups are you sharing between?   We are sharing between 2.

Share the objects between 2 boxes by putting 1 in the first box then 1 in the other box until all the objects have been shared equally.

How many are in each group?  6

How do you know that you have shared the objects equally? There are 6 in each box.

Now try these using objects and boxes or instead of boxes any containers or you can draw big circles to share the objects between.

1. Share 12 cubes/objects between 3 boxes.How many are in each box?

2. 24 children are put into 4 teams. Using the method shown work out how many children will be in each team.

3. There are 16 biscuits in a packet. 4 children share them. How many biscuits will each child have?

4. You have 18 sweets and share them between you and 2 of your friends. How many sweets will each of you have?

1. 4 x 2 =
2. 10 x 5 =
3. 11 x 10 =
4. 5 x 5 =
5. 2 x 10 =
6. 7 x 2 =
7. 9 x 5 =

Division

The symbol for divide looks like this  ÷

 Tom draws a bar model to divide 20 into 4 equal groups. This is what it looks like:

He writes 20 ÷ 4 = 5.

Using the bar model like Tom work out the answers:

EG.

15 ÷ 3 = 5

15

20 ÷ 4 =

16 ÷ 2 =

18 ÷ 3 =

25 ÷ 5 =

14 ÷ 2 =

21 ÷ 3 =

Order from largest to smallest:

1. 12, 86, 43, 23, 18, 54
2. 87, 98, 67, 44, 99, 48
3. 56, 65, 35, 76, 13, 23
4. 75, 57, 44, 32, 19, 80
