Zero as a Placeholder: Step-by-Step Example
29 October 2026
Understanding what zero does in a number can be tricky at first. This example helps your child see why zero is needed to keep the digits in the right places.
Worked example
Look at the number 204.
The digit 2 is in the hundreds place. That means 2 hundreds, or 200.
The 0 is in the tens place. That means there are no tens. The zero holds the tens place so the 2 stays in the hundreds place.
The digit 4 is in the ones place. That means 4 ones.
So, 204 means 2 hundreds, 0 tens, and 4 ones.
The correct answer is 204.
| Place | Value |
|---|---|
| Hundreds | 2 |
| Tens | 0 |
| Ones | 4 |
Key insight: Your child can now spot when zero is used as a placeholder, making sure numbers like 204 mean exactly what they should. They're ready to try similar questions and build confidence with place value.
