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 add them up.

1)
- 2 large squares → 2 × 100 = 200
- 2 rods → 2 × 10 = 20
- 1 small cube → 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
- Total: 100 + 50 + 3 =
153
✔ Answer: 153 blocks
---
3)
- 2 large squares → 2 × 100 = 200
- 4 rods → 4 × 10 = 40
- 5 small cubes → 5
- Total: 200 + 40 + 5 =
245
✔ Answer: 245 blocks
---
4)
- 3 large squares → 3 × 100 = 300
- 0 rods → 0
- 4 small cubes → 4
- Total: 300 + 0 + 4 =
304
✔ Answer: 304 blocks
---
5)
- 1 large square → 100
- 7 rods → 7 × 10 = 70
- 4 small cubes → 4
- Total: 100 + 70 + 4 =
174
✔ Answer: 174 blocks
---
6)
- 2 large squares → 200
- 5 rods → 50
- 2 small cubes → 2
- Total: 200 + 50 + 2 =
252
✔ Answer: 252 blocks
---
7)
- 5 large squares → 5 × 100 = 500
- 1 rod → 10
- 8 small cubes → 8
- Total: 500 + 10 + 8 =
518
✔ Answer: 518 blocks
---
8)
- 4 large squares → 4 × 100 = 400
- 6 rods → 6 × 10 = 60
- 7 small cubes → 7
- Total: 400 + 60 + 7 =
467
✔ Answer: 467 blocks
---
✔ Final Answers:
1)
221
2)
153
3)
245
4)
304
5)
174
6)
252
7)
518
8)
467
These represent the total number of blocks in each set, using place value (hundreds, tens, ones).
