Step-by-step solution for: Second Grade Place Value Worksheets
Absolutely! Let’s solve this worksheet titled “Combining Hundreds, Tens and Ones Sheet 2”.
The key instruction is:
> *Remember to count the Hundreds first, then the Tens, and then the Ones.*
This means we are practicing place value — adding numbers by breaking them into their hundreds, tens, and ones components.
---
We’ll solve each problem one by one. For problems with blanks (like #21–40), we’ll find the missing number.
---
These are straightforward additions:
1) 100 + 40 + 7 = 147
2) 300 + 20 + 9 = 329
3) 600 + 7 = 607 *(no tens, so just hundreds + ones)*
4) 200 + 70 + 5 = 275
5) 400 + 90 + 6 = 496
6) 100 + 80 + 5 = 185
7) 700 + 60 + 8 = 768
8) 600 + 50 + 1 = 651
9) 500 + 10 + 7 = 517
10) 300 + 50 + 8 = 358
11) 400 + 2 + 30 = 432 *(Note: 2 is ones, 30 is tens — order doesn’t matter in addition)*
12) 600 + 7 + 20 = 627
13) 80 + 100 + 4 = 184
14) 30 + 200 + 1 = 231
15) 50 + 7 + 500 = 557
16) 80 + 1 + 200 = 281
17) 8 + 70 + 400 = 478
18) 9 + 30 + 600 = 639
19) 2 + 700 + 60 = 762
20) 900 + 24 = 924 *(24 = 20 + 4 → 900 + 20 + 4)*

These have a blank — you need to find the missing addend.
Let’s solve them step by step.
21) 100 + ___ + 7 = 137
→ 100 + 7 = 107 → 137 - 107 = 30
22) 300 + 40 + ___ = 345
→ 300 + 40 = 340 → 345 - 340 = 5
23) ___ + 20 + 1 = 421
→ 20 + 1 = 21 → 421 - 21 = 400
24) ___ + 60 + 8 = 168
→ 60 + 8 = 68 → 168 - 68 = 100
25) 500 + 75 = ___
→ 500 + 75 = 575
26) 400 + 23 = ___
→ 400 + 23 = 423
27) 100 + ___ = 147
→ 147 - 100 = 47
28) 300 + ___ = 341
→ 341 - 300 = 41
29) 72 + ___ = 872
→ 872 - 72 = 800
30) 40 + 300 + ___ = 349
→ 40 + 300 = 340 → 349 - 340 = 9
31) 8 + 70 + ___ = 678
→ 8 + 70 = 78 → 678 - 78 = 600
32) 60 + 1 + 300 = ___
→ 60 + 1 + 300 = 361
33) 200 + 30 + 5 = ___
→ 200 + 30 + 5 = 235
34) 7 + ___ + 200 = 227
→ 7 + 200 = 207 → 227 - 207 = 20
35) 400 + ___ + 50 = 456
→ 400 + 50 = 450 → 456 - 450 = 6
36) 200 + 72 + 100 = ___
→ 200 + 100 = 300 → 300 + 72 = 372
37) 600 + 20 + 7 = ___
→ 600 + 20 + 7 = 627
38) 500 + ___ + 2 = 512
→ 500 + 2 = 502 → 512 - 502 = 10
39) 6 + ___ + 600 = 636
→ 6 + 600 = 606 → 636 - 606 = 30
40) 7 + 300 + ___ = 387
→ 7 + 300 = 307 → 387 - 307 = 80
