1.5 Odd and even numbers

Do you need counters or other objects to find out if

a number is odd or even?

Explain to your partner how you use the counters.

3 Colour the even numbers on the number track red.

Colour the odd numbers on the number track blue.

10
0 0 1 1 2 2 3 3 4 4 5 5 6 6 7 7 8 8 9 9 10

What pattern have you made?

4 Is each number odd or even?

Use the number track in question 3 to help you.

1 odd / even 7 odd / even

4 odd / even 10 odd / even

Let’s investigate

Work in a group of four. You will need a set of ten frames cut

into jigsaws.*

Put two numbers together to make ten, so that the ten frames

are whole again.

Discuss what you notice about the numbers in each ten

frame.

*See the additional teaching idea ‘Odd and even on a ten frame’ in the
Teacher’s Resource.
