📝 Explanation:

This worksheet helps students understand place value up to 1000. Each number is broken into:
- Hundreds: e.g., 200, 300, 500
- Tens: e.g., 30, 70, 90
- Ones: e.g., 6, 8, 4

When adding, you combine these parts:
- Example: 500 + 90 + 4 → 5 hundreds, 9 tens, 4 ones → 594

This builds number sense and prepares students for more complex addition and subtraction.

✔ All answers are correct and follow the place value rules.
