Let's solve this step by step. This worksheet is about
place value up to hundreds, using base-10 blocks.
Understanding the Blocks:
-
Large square (flat) = 100 blocks (hundreds)
-
Rod (long rectangle) = 10 blocks (tens)
-
Small cube (unit) = 1 block (ones)
We’ll count how many of each type are in each set and then add them up.

1)
- 2 large squares → 2 × 100 = 200
- 2 rods → 2 × 10 = 20
- 1 small cube → 1 × 1 = 1
Total: 200 + 20 + 1 = 221
✔ Answer: 221 blocks
---
2)
- 1 large square → 1 × 100 = 100
- 5 rods → 5 × 10 = 50
- 3 small cubes → 3 × 1 = 3
Total: 100 + 50 + 3 = 153
✔ Answer: 153 blocks

3)
- 2 large squares → 2 × 100 = 200
- 4 rods → 4 × 10 = 40
- 5 small cubes → 5 × 1 = 5
Total: 200 + 40 + 5 = 245
✔ Answer: 245 blocks
---
4)
- 3 large squares → 3 × 100 = 300
- 0 rods → 0
- 4 small cubes → 4 × 1 = 4
Total: 300 + 0 + 4 = 304
✔ Answer: 304 blocks

5)
- 1 large square → 1 × 100 = 100
- 7 rods → 7 × 10 = 70
- 4 small cubes → 4 × 1 = 4
Total: 100 + 70 + 4 = 174
✔ Answer: 174 blocks
---
6)
- 2 large squares → 2 × 100 = 200
- 5 rods → 5 × 10 = 50
- 2 small cubes → 2 × 1 = 2
Total: 200 + 50 + 2 = 252
✔ Answer: 252 blocks
---
7)
- 5 large squares → 5 × 100 = 500
- 1 rod → 1 × 10 = 10
- 8 small cubes → 8 × 1 = 8
Total: 500 + 10 + 8 = 518
✔ Answer: 518 blocks
---
8)
- 4 large squares → 4 × 100 = 400
- 5 rods → 5 × 10 = 50
- 9 small cubes → 9 × 1 = 9
Total: 400 + 50 + 9 = 459
✔ Answer: 459 blocks
