Tens and ones is the idea that a number like 34 means three bundles of ten and four loose ones. It sounds simple to grown-ups, but it is one of the biggest steps in early maths, and most children reach it at the end of UKG or in Class 1. The game above uses the oldest classroom trick for teaching it: bundling sticks. Your child sees a pile of loose sticks. Each tap ties ten of them into a bundle with a red band. When fewer than ten are left, Golu asks "How many tens?" and then "How many ones?", and finishes with the full sentence, for example "Thirty-four is three tens and four ones", and चौंतीस में तीन दहाई और चार इकाई.
What is place value?
In the number 34, the 3 is worth thirty and the 4 is worth four. The value of a digit depends on its place: the right-hand place counts ones, the next place counts tens. In Hindi the places are called इकाई (ikai, ones) and दहाई (dahai, tens), which many Indian schools teach from UKG. Children who really understand this find adding and subtracting bigger numbers much easier later, because "carrying" is just making a new bundle of ten.
Why bundling sticks works
A written digit is abstract; a bundle of ten sticks is something you can hold. When children tie the bundles themselves, they see that the bundle is still ten single sticks, just grouped. That is the key understanding. The game counts the bundle-tying for your child so they can focus on the result, but the best learning happens when you do it with real sticks too.
How to use this page
- Tap the pile to tie a bundle of ten. Golu says "Tie another ten!" until fewer than ten are left.
- Answer "How many tens?", then "How many ones?". Each question is spoken; 🔊 repeats it.
- The age setting changes the numbers: up to 29 for most ages, up to 59 at age 5-6.
- Wrong answers get a hint, never a buzzer: Golu names the tapped number, then the answer glows, then 👆 points.
- Four numbers make one round, then a marble drops in the Goli Jar.

Is my child ready for tens and ones?
Check three things first. Can your child count objects to 20 without skipping? Do they know that a group stays the same number however you arrange it? Can they count by tens (10, 20, 30)? If yes, they are ready. If not, spend time on counting 11 to 20 and skip counting first. This page is a stretch goal for UKG; there is no hurry if your child is four.
How to teach tens and ones at home
Ice-cream sticks and rubber bands
Give your child 30 to 40 ice-cream sticks, matchsticks (used, and supervised) or straws. Count out ten, band them, and repeat. Then ask: how many bundles? how many loose? Write the number together.
Money makes it real
Ten-rupee notes and one-rupee coins are perfect tens and ones. "You have three ten-rupee notes and four one-rupee coins. How much is that?" See money for kids for more.
Egg cartons and ten-frames
Fill ten-cup cartons with beans. Each full carton is a ten. Empty cups show how far you are from the next ten, which links back to number bonds to 10.
Say it both ways
Practise "forty-six" and "four tens and six ones" as two names for the same thing. In Hindi, छियालीस and चार दहाई छह इकाई.
Watch for the "20 has zero ones" moment. Children are often surprised that the ones can be zero. Make it a celebration: "No loose sticks at all!"
Common mix-ups
- Swapping digits (writing 43 for 34), especially with teen numbers where English says the ones first. Always point to the bundles first, then the loose ones.
- Counting bundles as ones. Ask "How many sticks are in this bundle?" and count one bundle fully once.
- Frustration. Go back to smaller numbers. Praise the effort: "You tied every bundle so carefully."
For every learner
Tapping is the only gesture needed, and all instructions are spoken, so children who do not read yet can play. Children with fine-motor difficulties may find real rubber bands hard; a cup for each ten works just as well. Autistic children often enjoy the tidy order of bundles. Bilingual families can switch languages with अ+A. Keep screen time short and shared, and follow it with real bundling on the floor.
Questions to ask while you play
Before tapping, ask your child to guess: "Do you think there will be two bundles or three?" After the bundles are tied, ask "How many sticks are there in all the bundles together?" and count by tens: ten, twenty, thirty. Then add the loose ones: thirty-one, thirty-two. This links bundles with counting by tens. For a challenge, ask "If we get one more stick, how many ones will there be? What if we get six more?" When ten loose sticks appear, a new bundle can be tied, which is the idea behind carrying in addition. You can write each number on paper in a two-column table with a T for tens and an O for ones, the same way many Class 1 textbooks do.
