What place value means
In 247, the 2 is worth 200 because it sits in the hundreds column, the 4 is worth 40 in the tens column, and the 7 is worth 7 in the ones column. Every column is worth ten times the one on its right, which is why ten ones make one ten, and ten tens make one hundred.
Ideas for using the game
- Ask your child to say the number out loud as they build it, for example “two hundreds, four tens, seven ones”.
- Use the hint to check a wrong build, then build it again without it.
- Ask what changes when you add one more ten, or take away one hundred.

Place value questions
What is place value?
Place value is the worth of a digit based on its column. In 247, the 2 is 200, the 4 is 40 and the 7 is 7.
What age is this game for?
It suits children learning to build three-digit numbers, roughly from first grade, but you can use it at any level that feels right.
Does the game save any progress?
No. Stars are shown on the page while you play and reset when you choose Play again. Nothing is saved or sent anywhere.
How do I help my child who gets stuck?
Use the hint, then ask them to name what each column is worth. Building the number again with the blocks is a good way to see the pattern.
