Odd and even numbers for Class 2 is one of those topics that clicks in a single afternoon if you teach it with real things first. Children who learn it only as a rule to remember often mix it up; children who have paired up socks and shoes almost never do.

Quick answer:
- Even numbers can be shared into pairs with nothing left over: 2, 4, 6, 8, 10 and so on.
- Odd numbers always have one left over when you make pairs: 1, 3, 5, 7, 9 and so on.
- Last-digit rule: a number is even if it ends in 0, 2, 4, 6 or 8, and odd if it ends in 1, 3, 5, 7 or 9.
- Zero is even.
How to teach odd and even with pairs
Start with things that naturally come in twos. Put a heap of socks on the bed (or shoes, chappals, bangles or spoons). Ask your child to make pairs.
- With 6 socks, every sock has a partner. Say: 6 is even. Everyone has a partner.
- With 7 socks, one sock is left alone. Say: 7 is odd. One is left without a partner.
Repeat with 4, 5, 8, 9 and 10 objects. Let your child predict before they pair: Do you think 9 will have one left over? Then check together.
A second way is a partner line. Ask children in a class (or family members at home) to stand in twos. If someone is left without a partner, the number of people is odd. Children love this because they are the counters.
Drawing pairs on paper
Next, draw dots in two rows, like domino dots. 8 dots make two neat rows of 4. 9 dots make two rows of 4 with one extra dot sticking out. That sticking-out dot is what makes a number odd. Ask children to draw dot pictures for numbers from 1 to 12 and sort them into an odd box and an even box.
The last-digit rule for bigger numbers
Pairing works well up to about 20, but nobody wants to pair 347 socks. Once children understand the idea, show them that only the ones digit matters:
| Last digit | Odd or even? | Examples |
|---|---|---|
| 0, 2, 4, 6, 8 | Even | 30, 52, 74, 96, 118, 500 |
| 1, 3, 5, 7, 9 | Odd | 21, 43, 65, 87, 109, 999 |
Why does this work? Tens and hundreds can always be shared into pairs, because 10 is even. So the only part that might leave one over is the ones digit. You do not need to explain this to every child, but curious Class 2 children often enjoy knowing the reason.
A common mistake is looking at the first digit. A child may say 38 is odd because 3 is odd. Cover everything except the last digit with your finger and ask again.
Odd and even numbers 1 to 100: the colouring activity
Draw or print a 1 to 100 number grid (10 rows of 10). Ask your child to colour all the even numbers yellow and leave the odd numbers white. In a grid of 10 columns, they will see a striped pattern: the 2nd, 4th, 6th, 8th and 10th columns are all yellow. That stripe is a powerful picture of the last-digit rule.
Questions to ask afterwards:
- How many even numbers are there from 1 to 100? (50)
- How many odd numbers? (50)
- What do all the numbers in a yellow column end with? (the same even digit)
Children who can say the number names will also enjoy reading out a full column aloud. For writing them, see our number names 1 to 100 guide.
Odd and even patterns for curious kids
Once the basics are secure, try adding pairs of numbers and see what happens:
| Add | Example | Answer is always |
|---|---|---|
| even + even | 4 + 6 = 10 | even |
| odd + odd | 3 + 5 = 8 | even |
| odd + even | 7 + 2 = 9 | odd |
| even + odd | 8 + 5 = 13 | odd |
Use the dot pictures to show why: two odd numbers each have one sticking-out dot, and those two extra dots make a new pair. This pattern is a handy way to check addition answers. If a child adds 15 + 23 and gets 39, they can spot the mistake because odd + odd must be even. The right answer is 38.
Skip counting is closely linked: counting in 2s from 0 gives the even numbers, and counting in 2s from 1 gives the odd numbers. Our skip counting worksheets guide has more practice.

3 quick odd and even games
- Odd or even jump: call out a number. Children jump if it is even and clap if it is odd.
- Dice pairs: roll two dice, add the dots and say odd or even before counting. Score a point for every correct guess.
- House number hunt: on a walk, read house or shop numbers and say odd or even. Some streets have even numbers on one side and odd on the other.

Frequently asked questions
What are odd and even numbers for kids?
Even numbers can be split into pairs with nothing left over, such as 2, 4, 6 and 8. Odd numbers always have one left over, such as 1, 3, 5 and 7.
Is 0 an odd or even number?
Zero is an even number. It ends in 0, and in the pattern even, odd, even, odd it comes just before 1, which is odd.
How do you know if a big number is odd or even?
Look only 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.
How many odd numbers are there from 1 to 100?
There are 50 odd numbers and 50 even numbers from 1 to 100. The odd numbers start at 1 and end at 99.
What happens when you add two odd numbers?
Two odd numbers always add up to an even number, for example 3 + 5 = 8. The two extra ones join to make a new pair.
