Let's solve the problem step by step using
Base 10 Blocks.
---
🔢 Understanding Base 10 Blocks:
-
1 small cube = 1
-
1 long (rod) = 10 (10 cubes)
-
1 flat (square) = 100 (10 × 10 cubes)
-
1 big cube (1000 block) = 1000 (10 × 10 × 10 cubes)
We will count the blocks in each image and find the correct number.

🟨 First Image:
Blocks shown:
-
Thousands: 4 big cubes → 4 × 1000 =
4000
-
Hundreds: 3 flats → 3 × 100 =
300
-
Tens: 2 longs → 2 × 10 =
20
-
Ones: 9 small cubes → 9 × 1 =
9
Now add them up:
> 4000 + 300 + 20 + 9 =
4329
✔ So, the correct number is
4329
👉 Circle
4329

🟨 Second Image:
Blocks shown:
-
Thousands: 8 big cubes → 8 × 1000 =
8000
-
Hundreds: 5 flats → 5 × 100 =
500
-
Tens: 0 longs → 0 × 10 =
0
-
Ones: 1 small cube → 1 × 1 =
1
Add them up:
> 8000 + 500 + 0 + 1 =
8501
✔ So, the correct number is
8501
👉 Circle
8501

✔ Final Answers:
-
First group: Circle
4329
-
Second group: Circle
8501
