Let's solve each problem on the
Base Ten Blocks Worksheet step by step. This worksheet asks students to identify numbers using base-10 blocks, then write them in:
-
Expanded form (e.g., 300 + 40 + 5)
-
Word form (e.g., three hundred forty-five)
We'll go through each of the six problems.

🔢 Base Ten Blocks Key:
-
Large cube = 100 (hundred)
-
Flat square = 10 (ten)
-
Small cube = 1 (one)
---
🔹 Problem 1:
Blocks shown:
- 1 large cube (100)
- 2 flat squares (2 × 10 = 20)
- 3 small cubes (3 × 1 = 3)
Total:
100 + 20 + 3 =
123
Expanded Form:
100 + 20 + 3
Word Form:
One hundred twenty-three

🔹 Problem 2:
Blocks shown:
- 2 large cubes (2 × 100 = 200)
- 3 flat squares (3 × 10 = 30)
- 4 small cubes (4 × 1 = 4)
Total:
200 + 30 + 4 =
234
Expanded Form:
200 + 30 + 4
Word Form:
Two hundred thirty-four

🔹 Problem 3:
Blocks shown:
- 3 flat squares (3 × 10 = 30)
- 6 small cubes (6 × 1 = 6)
Total:
30 + 6 =
36
Expanded Form:
30 + 6
Word Form:
Thirty-six

🔹 Problem 4:
Blocks shown:
- 2 large cubes (2 × 100 = 200)
- 1 flat square (1 × 10 = 10)
- 2 small cubes (2 × 1 = 2)
Total:
200 + 10 + 2 =
212
Expanded Form:
200 + 10 + 2
Word Form:
Two hundred twelve

🔹 Problem 5:
Blocks shown:
- 1 large cube (100)
- 1 flat square (10)
- 8 small cubes (8)
Total:
100 + 10 + 8 =
118
Expanded Form:
100 + 10 + 8
Word Form:
One hundred eighteen
---
🔹 Problem 6:
Blocks shown:
- 3 large cubes (3 × 100 = 300)
- 5 flat squares (5 × 10 = 50)
- 7 small cubes (7 × 1 = 7)
Total:
300 + 50 + 7 =
357
Expanded Form:
300 + 50 + 7
Word Form:
Three hundred fifty-seven

✔ Final Answers:
| # | Expanded Form | Word Form |
|---|-----------------------|------------------------|
| 1 | 100 + 20 + 3 | One hundred twenty-three |
| 2 | 200 + 30 + 4 | Two hundred thirty-four |
| 3 | 30 + 6 | Thirty-six |
| 4 | 200 + 10 + 2 | Two hundred twelve |
| 5 | 100 + 10 + 8 | One hundred eighteen |
| 6 | 300 + 50 + 7 | Three hundred fifty-seven |
