Grade 4 Rounding Worksheets | Free Printables | Math Worksheets - Free Printable

Problem Description:

The task is to round numbers to the nearest 100 and the nearest 1,000. The worksheet provides a list of numbers that need to be rounded accordingly.

Solution Approach:

1. Rounding to the Nearest 100:
- Look at the digit in the tens place.
- If the tens digit is 5 or greater, round up.
- If the tens digit is less than 5, round down.

2. Rounding to the Nearest 1,000:
- Look at the digit in the hundreds place.
- If the hundreds digit is 5 or greater, round up.
- If the hundreds digit is less than 5, round down.

Step-by-Step Solution:

#### Part 1: Round to the Nearest 100
1. 712: The tens digit is 1 (less than 5). Round down → 700
2. 365: The tens digit is 6 (5 or greater). Round up → 400
3. 349: The tens digit is 4 (less than 5). Round down → 300
4. 850: The tens digit is 5 (5 or greater). Round up → 900
5. 123: The tens digit is 2 (less than 5). Round down → 100
6. 681: The tens digit is 8 (5 or greater). Round up → 700
7. 450: The tens digit is 5 (5 or greater). Round up → 500
8. 505: The tens digit is 0 (less than 5). Round down → 500
9. 173: The tens digit is 7 (5 or greater). Round up → 200
10. 260: The tens digit is 6 (5 or greater). Round up → 300

#### Part 2: Round to the Nearest 1,000
11. 3,850: The hundreds digit is 8 (5 or greater). Round up → 4,000
12. 7,241: The hundreds digit is 2 (less than 5). Round down → 7,000
13. 9,402: The hundreds digit is 4 (less than 5). Round down → 9,000
14. 6,230: The hundreds digit is 2 (less than 5). Round down → 6,000
15. 8,880: The hundreds digit is 8 (5 or greater). Round up → 9,000
16. 2,500: The hundreds digit is 5 (5 or greater). Round up → 3,000
17. 4,120: The hundreds digit is 1 (less than 5). Round down → 4,000
18. 6,870: The hundreds digit is 8 (5 or greater). Round up → 7,000
19. 6,130: The hundreds digit is 1 (less than 5). Round down → 6,000
20. 1,500: The hundreds digit is 5 (5 or greater). Round up → 2,000
