This week we are going to divide by 2, recognise odd and even numbers and divide by 5 using knowledge of sharing and grouping.
Divide by 2
We can use this to write a division and a multiplication sentence:
6 ÷ 3 = 2
3 x 2 = 6
Now have a go:
Complete the number sentences to match:
Is there a link between halving and dividing by 2?
What do you notice when you write a division number sentence and a multiplication sentence?
Let’s look at another method by using a bar model and sharing to divide by 2:
There are 2 groups.
There are 6 in each group.
12 ÷ 2 = 6
Have a go at these using the bar model:
Draw arrays to help you work out the answers.

5 x 2 =
6 x 3 =
10 x 5 =
4 x 3 =
5 x 5 =
11 x 2 =
Recognise odd and even numbers
a) Click on the link for more information
b) Colour all the odd and even numbers on a hundred square. If you can access the internet use this number square:
Colour even numbers in one colour and odd numbers in another. What do you notice?
Maths Activity 3
Draw chips and peas to work out the answers:
27 + 12 =
14 = 14 =
54 + 21 =
44 + 22 =
36 + 32 =
Dividing by 5
Using the number square on Topmarks colour in all the multiples of 5
Or use the one below.
What do you notice about the numbers?
Can you explain the pattern?
How can this help you divide by 5?
Using any objects, have a go at the above and check below to see if you have the same as me.
I made 6 towers of 5.
6 towers of 5 is the same as 30.
30 is the same as 6 towers of 5.
Did you get the same answer?
Have a go at these. Use the number square you coloured in to help or use your knowledge of counting in 5’s:
