Circle the number represented by the base-10 blocks in this educational math worksheet.

Let's solve the problem step by step using Base 10 Blocks.

---

🔢 Understanding Base 10 Blocks:

- 1 cube = 1 unit
- 1 long (rod) = 10 units
- 1 flat (square) = 100 units

We need to count how many flats, longs, and cubes are in each image, then determine the total number.

🔹 First Image:

#### Count the blocks:
- Flats (100s): There are 3 flats → 3 × 100 = 300
- Longs (10s): There are 5 longs → 5 × 10 = 50
- Cubes (1s): There are 2 cubes → 2 × 1 = 2

Now add them:
> 300 + 50 + 2 = 352

✔ So, the number shown is 352

👉 Circle: 352

🔹 Second Image:

#### Count the blocks:
- Flats (100s): There are 5 flats → 5 × 100 = 500
- Longs (10s): There are 7 longs → 7 × 10 = 70
- Cubes (1s): There are 6 cubes → 6 × 1 = 6

Now add them:
> 500 + 70 + 6 = 576

✔ So, the number shown is 576

👉 Circle: 576

✔ Final Answers:

1. First set → 352
2. Second set → 576

You should circle 352 and 576 respectively.
