2nd Grade Place Value Math Worksheet for Addition of Hundreds, Tens, and Ones.

Problem Explanation:

The task involves understanding place value and converting the given hundreds, tens, and ones into a single number. The key is to remember that:
- Hundreds represent the digit in the hundreds place.
- Tens represent the digit in the tens place.
- Ones represent the digit in the ones place.

For example, "3 HUNDREDS + 2 TENS" means you have 300 (from the hundreds) and 20 (from the tens), which together make 320.

Solution:

Let's solve each problem step by step:

1. 3 HUNDREDS + 2 TENS =
- Hundreds: 300
- Tens: 20
- Total: 300 + 20 = 320

2. 2 HUNDREDS + 3 TENS + 5 ONES =
- Hundreds: 200
- Tens: 30
- Ones: 5
- Total: 200 + 30 + 5 = 235

3. 4 HUNDREDS + 6 TENS + 2 ONES =
- Hundreds: 400
- Tens: 60
- Ones: 2
- Total: 400 + 60 + 2 = 462

4. 6 HUNDREDS + 2 TENS + 9 ONES =
- Hundreds: 600
- Tens: 20
- Ones: 9
- Total: 600 + 20 + 9 = 629

5. 2 HUNDREDS + 7 TENS =
- Hundreds: 200
- Tens: 70
- Total: 200 + 70 = 270

6. 5 TENS + 7 ONES =
- Tens: 50
- Ones: 7
- Total: 50 + 7 = 57

7. 5 HUNDREDS + 3 TENS + 2 ONES =
- Hundreds: 500
- Tens: 30
- Ones: 2
- Total: 500 + 30 + 2 = 532

8. 8 TENS + 5 ONES =
- Tens: 80
- Ones: 5
- Total: 80 + 5 = 85

9. 4 HUNDREDS + 8 ONES =
- Hundreds: 400
- Ones: 8
- Total: 400 + 8 = 408

10. 3 HUNDREDS + 4 TENS =
- Hundreds: 300
- Tens: 40
- Total: 300 + 40 = 340

11. 7 HUNDREDS + 3 TENS + 8 ONES =
- Hundreds: 700
- Tens: 30
- Ones: 8
- Total: 700 + 30 + 8 = 738

12. 6 HUNDREDS + 4 TENS =
- Hundreds: 600
- Tens: 40
- Total: 600 + 40 = 640

13. 3 HUNDREDS + 4 ONES =
- Hundreds: 300
- Ones: 4
- Total: 300 + 4 = 304

14. 5 HUNDREDS + 4 TENS + 6 ONES =
- Hundreds: 500
- Tens: 40
- Ones: 6
- Total: 500 + 40 + 6 = 546

15. 3 HUNDREDS + 2 TENS + 7 ONES =
- Hundreds: 300
- Tens: 20
- Ones: 7
- Total: 300 + 20 + 7 = 327

16. 6 HUNDREDS + 1 TEN + 8 ONES =
- Hundreds: 600
- Tens: 10
- Ones: 8
- Total: 600 + 10 + 8 = 618

17. 4 HUNDREDS + 7 ONES =
- Hundreds: 400
- Ones: 7
- Total: 400 + 7 = 407

18. 3 HUNDREDS + 9 TENS =
- Hundreds: 300
- Tens: 90
- Total: 300 + 90 = 390

19. 6 HUNDREDS + 9 TENS + 8 ONES =
- Hundreds: 600
- Tens: 90
- Ones: 8
- Total: 600 + 90 + 8 = 698

20. 2 HUNDREDS + 9 ONES =
- Hundreds: 200
- Ones: 9
- Total: 200 + 9 = 209
