You're given a math worksheet titled
“10 LESS. 10 MORE” with the directions:
> *Complete each box by writing 10 more and 10 less.*
This means for each number shown in the middle of a box, you need to:
- Write the number that is
10 less (subtract 10) in the top cell.
- Write the number that is
10 more (add 10) in the bottom cell.
Let’s go through each box one by one:
---
Box 1: Middle = 459
- 10 less: 459 – 10 =
449
- 10 more: 459 + 10 =
469

## 💡 Explanation:
This exercise helps build
number sense — understanding how numbers relate to each other when adding or subtracting 10. It reinforces place value: only the
tens digit changes when you add or subtract 10. For example:
- In 459 → 449 (tens digit goes from 5 to 4)
- In 459 → 469 (tens digit goes from 5 to 6)
This is foundational for mental math and later arithmetic operations.
