Fascinating Fact:

You can share an even number of biscuits fairly between two friends, like 10 biscuits giving 5 each.

In KS1 Maths, pupils learn that even numbers make neat pairs and odd numbers leave one out. We use pairing and counting in twos to test whether a number is even or odd.

Key Terms

Even number: A number that can be shared into two equal groups, like 8 = 4 + 4.
Odd number: A number that cannot be split into two equal groups without one left over, like 7.
Pair: Two things matched together; even numbers can be made from pairs.

Practise odd and even with quick pairing in the Numeracy Game before you try the quiz.

Frequently Asked Questions (Click to see answers)

How can I tell if a number is even in Year 1?

Try pairing objects. If nothing is left over, the number is even. You can also count in twos to reach the number exactly.

Is zero an odd number or an even number?

Zero is an even number. It can be split into two equal groups of zero without anything left over.

What’s a quick test for odd or even?

Look at the last digit. If it is 0, 2, 4, 6, or 8 the number is even. If it is 1, 3, 5, 7, or 9 the number is odd.
