This week we are going to divide numbers by sharing objects to work out the answer.
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?
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:
15 ÷ 3 = 5
20 ÷ 4 =
16 ÷ 2 =
18 ÷ 3 =
25 ÷ 5 =
14 ÷ 2 =
21 ÷ 3 =
