Odd and even numbers are one of the first number patterns a child can see with their own eyes. Put seven socks on the bed and try to make pairs: three pairs and one lonely sock. Put eight socks there and every sock has a partner. That is the whole idea, and this page turns it into a laundry game. Your child taps socks from a colourful pile, hangs matching pairs on a washing line, and then answers "Is seven odd or even?" in Hindi or English. It suits children aged 5 to 6, in UKG and class 1, and it is free in any browser.
What are odd and even numbers? (a child-sized definition)
For a five-year-old, forget "divisible by two". Use pairs:
- Even number (सम संख्या): every one has a partner. 2, 4, 6, 8 and 10 are even.
- Odd number (विषम संख्या): one is left over with no partner. 1, 3, 5, 7 and 9 are odd.
This pairing definition is exactly what grown-up maths means, so your child never has to unlearn it. It also answers the classic questions. Is 1 odd or even? Odd, because one sock alone has no partner. Is 7 odd or even? Odd, because three pairs leave one sock. Is 0 an even number? Yes: with no socks, nobody is left without a partner. Most children find that last one very funny.
The UK Reception goal for number already mentions odd and even patterns, and in India odd and even numbers usually appear in class 1 or class 2 maths. US first grade meets them too. So this is a stretch topic for UKG and a core topic for class 1.
How to play the odd and even numbers game
Socks: make pairs on the washing line
Between 3 and 10 bright socks lie in a pile. Golu says "Tap a sock to find its partner." Each tap takes a sock and its matching partner and hangs the pair on the washing line with two pegs. When only one sock is left, your child hears "This sock has no partner!" Then comes the question, "Is seven odd or even?", with two big buttons: Odd / विषम and Even / सम. After the answer the voice explains why, for example "Seven is odd. One is left over." or "Eight is even. Every one has a partner."
Odd or even: dots in pairs
The second tab shows a number with the same number of dots arranged in pairs, like the dots on a domino. For the 5-6 age band the numbers go up to 20; for younger settings they stay between 1 and 10. Your child looks for a dot without a partner and taps Odd or Even. This tab moves from real objects to a picture of the number, which is the next step towards seeing it without counting.
Hints, sound and the Goli Jar
The game never says "wrong". If your child taps Even for seven, they hear a gentle hint, then the right button glows, and then Golu points to it. The 🔊 button replays the question as often as your child wants. Every word is spoken in Hindi and English; the अ+A button in the header changes the order or picks one language. After a few short rounds a marble rolls into the Goli Jar, and the end card gives a real-world mission with the laundry basket.
How to teach odd and even numbers by age
| Age | What is realistic | Try this |
|---|---|---|
| 3-4 years | Makes pairs: shoes, socks, gloves. No numbers yet. | "Find the partner for this shoe." Use the word pair often. |
| 4-5 years | Shares things between two people and notices "one extra". | Share 5 biscuits between two teddies. What happens to the last one? |
| 5-6 years (UKG) | Sorts numbers 1 to 10 into odd and even using objects. | Socks tab with 3 to 10 socks. Say "every one has a partner" aloud. |
| 6-7 years (class 1) | Odd and even numbers 1 to 20, then spots the pattern in the last digit. | Odd or even tab up to 20. Colour even numbers on a number chart. |
Five to ten minutes is enough. Play a few rounds together, talk about the pairs, and then go and make pairs with real things. Screens work best when a grown-up sits alongside; for under-twos, real socks and your voice beat any screen.
Odd and even activities with real objects
Hands-on activities make the idea stick far better than a rule. Try one a day:
- Laundry pairs. Fold the washing together. Count the socks, pair them, and ask "odd or even?" A missing sock is a perfect odd-number lesson.
- Two-by-two walk. Line up soft toys to walk in twos like children going to assembly. If one toy walks alone, the number is odd.
- Roti sharing. Share rotis, laddoos or grapes fairly between two people. If the last one has to be broken, the number was odd. The halves for kids page shows how to cut that last one fairly.
- Hopscotch numbers. Chalk 1 to 10 on the floor. Your child hops on even numbers with two feet and odd numbers with one foot.
- Stairs. Climb stairs saying "odd, even, odd, even". It is a rhythm and a pattern for kids at the same time.
Odd and even numbers 1 to 20: the pattern
Once your child has paired up plenty of objects, show them the list. Write numbers 1 to 20 in two rows of ten and colour the even numbers.
| Even numbers (सम) | Odd numbers (विषम) |
|---|---|
| 2, 4, 6, 8, 10 | 1, 3, 5, 7, 9 |
| 12, 14, 16, 18, 20 | 11, 13, 15, 17, 19 |
Children in class 1 often spot the trick themselves: numbers take turns, odd, even, odd, even. Older children notice that the last digit tells you. If a number ends in 0, 2, 4, 6 or 8 it is even; if it ends in 1, 3, 5, 7 or 9 it is odd. Keep this last-digit rule for later, when your child can already explain the pairs. A rule learned without the picture is quickly forgotten. The counting 1 to 100 chart is a good place to see the pattern run all the way to 100.
Counting in twos (2, 4, 6, 8, 10) is the same idea as a chant. It helps later with addition for kids, because even plus even is always even, and with doubles such as 3 + 3 = 6.
Odd and even numbers in Hindi (sam aur visham sankhya)
In Hindi, even numbers are सम संख्याएँ (sam sankhya) and odd numbers are विषम संख्याएँ (visham sankhya). Many Hindi-medium schools also say जोड़ा (a pair) when they teach it, which matches the socks game. In bilingual homes, let your child hear both words; the game says each answer in both languages, so "even" and सम become two names for the same idea.
Is there an odd and even numbers worksheet or chart?
There is no PDF, but you can print this page from your browser. The table above works as a small odd and even numbers chart for 1 to 20. For a quick worksheet, draw ten boxes, put a few dots in each, and ask your child to circle the boxes where every dot has a partner.
When odd and even feels hard
If your child mixes up the words, that is normal: "odd" and "even" are strange words that do not sound like their meaning. Go back to objects and say "partner" and "left over" instead, and add the proper words later. Praise the effort ("you checked every sock"), not being clever. For children with autism, the predictable washing line and the same voice every time can help; start with 3 or 4 socks. For children with speech delay, pointing to the button is a full answer. Calm motion, calm sound and fewer choices are in Settings, behind a grown-up check. If you are worried about your child's development, talk to your paediatrician.
