Grade 2 rounding worksheet for rounding two-digit numbers to the nearest 10.

Let’s go through each problem step by step.

We are rounding 2-digit numbers to the nearest 10.
Here’s how we do it:

- Look at the ones digit (the last digit).
- If the ones digit is 5 or more, round up.
- If the ones digit is 4 or less, round down.

Example: 89 → ones digit is 9 → round up → 90 ✔

Now let’s solve each one:

1. 82 → ones digit = 2 → less than 5 → round down → 80
2. 84 → ones digit = 4 → less than 5 → round down → 80
3. 92 → ones digit = 2 → less than 5 → round down → 90
4. 51 → ones digit = 1 → less than 5 → round down → 50
5. 13 → ones digit = 3 → less than 5 → round down → 10
6. 70 → already ends in 0 → stays 70
7. 66 → ones digit = 6 → 5 or more → round up → 70
8. 97 → ones digit = 7 → 5 or more → round up → 100
9. 87 → ones digit = 7 → 5 or more → round up → 90
10. 29 → ones digit = 9 → 5 or more → round up → 30
11. 21 → ones digit = 1 → less than 5 → round down → 20
12. 78 → ones digit = 8 → 5 or more → round up → 80
13. 28 → ones digit = 8 → 5 or more → round up → 30
14. 36 → ones digit = 6 → 5 or more → round up → 40
15. 57 → ones digit = 7 → 5 or more → round up → 60
16. 24 → ones digit = 4 → less than 5 → round down → 20
17. 47 → ones digit = 7 → 5 or more → round up → 50
18. 20 → already ends in 0 → stays 20
19. 53 → ones digit = 3 → less than 5 → round down → 50
20. 95 → ones digit = 5 → 5 or more → round up → 100
21. 41 → ones digit = 1 → less than 5 → round down → 40

Double-checking a few tricky ones:
- 97 → rounds to 100? Yes, because 97 is closer to 100 than to 90.
- 95 → also rounds to 100 — rule says 5 or above rounds up.
- 70 and 20 stay same — correct, they’re already multiples of 10.
