You're looking at a
base-10 blocks worksheet titled
“What Number Am I?”. The goal is to count the base-10 blocks in each row and write the total number they represent.
---
🧩 Base-10 Block Key:
-
Flat = 100 (a 10x10 grid)
-
Long = 10 (a 10x1 rod)
-
Unit (or cube) = 1 (single square)
We’ll go row by row.

## 🔢 Row 1:
- Flats:
3 → 3 × 100 =
300
- Longs:
4 → 4 × 10 =
40
- Units:
5 → 5 × 1 =
5
✔ Total:
300 + 40 + 5 = 345
---
## 🔢 Row 2:
- Flats:
2 → 2 × 100 =
200
- Longs:
6 → 6 × 10 =
60
- Units:
3 → 3 × 1 =
3
✔ Total:
200 + 60 + 3 = 263
---
## 🔢 Row 3:
- Flats:
1 → 1 × 100 =
100
- Longs:
8 → 8 × 10 =
80
- Units:
2 → 2 × 1 =
2
✔ Total:
100 + 80 + 2 = 182
---
## 🔢 Row 4:
- Flats:
4 → 4 × 100 =
400
- Longs:
2 → 2 × 10 =
20
- Units:
1 → 1 × 1 =
1
✔ Total:
400 + 20 + 1 = 421
---
## 🔢 Row 5:
- Flats:
5 → 5 × 100 =
500
- Longs:
7 → 7 × 10 =
70
- Units:
9 → 9 × 1 =
9
✔ Total:
500 + 70 + 9 = 579
