What children learn in Level 10
- These little cubes are ones. Each cube is worth 1.
- Here are 13 ones. Let's bundle 10 of them together. Tap 10 ones!
- 10 ones make 1 ten! Now there is 1 ten and 3 ones. That's still 13.
- Tens can be bundled too. Here are 12 tens. Tap 10 of them to make a hundred!
- 10 tens make 1 hundred! 1 hundred and 2 tens is 120.
- A hundred is 10 tens, or 100 ones! 3 hundreds is 300. 9 hundreds is 900.
- Remember: 10 ones make a ten, and 10 tens make a hundred. Let's practice!
