What it is
An even number can be split into pairs, or into two equal groups, with nothing left over. An odd number always has one left over. Every even number is a double, like 14 = 7 + 7, and every odd number is a double plus 1, like 15 = 7 + 7 + 1.
What comes next
Equal groups and arrays, which build on equal groups to start multiplication.
How to teach it
- Pair up real things, like socks or shoes. Is one left without a partner?
- Count by 2s and notice that you say only the even numbers.
- Look at the last digit. 0, 2, 4, 6 and 8 are even.
- Connect it to doubles. 7 + 7 = 14, so 14 is even.
Common mistakes
- Thinking a number is odd because it looks big, or even because it "feels" round.
- Looking at the first digit instead of the last one in numbers like 12 or 21.
- Splitting an odd number into two equal parts and forgetting the 1 left over.
