Order and sort numbers into odd and even sets
I can explain how numbers that are made out of pairs of 2 are even numbers and numbers that cannot be made out of pairs are odd numbers.
Lesson details
Key learning points
- We can group representations of numbers according to whether they are made of pairs or not.
- Shapes representing numbers can be grouped according their shape and to whether they are made of pairs or not.
- The language of odd and even can be used to describe numbers made of pairs or not made of pairs.
- --- is made of -- pairs. It is an even number but --- is not made of pairs. It is an odd number.
- Numbers can be sorted into odds and evens.
Common misconception
Children may see the pairs in odd numbers and think it is an even number.
Ensure children are looking for the extra one that makes a number odd. Provide opportunities to group other odd sets e.g. pairs of socks, pairs of hands / feet and realising an odd number always has an 'odd' one.
