This worksheet helps students practice place value by counting base 10 blocks and selecting the matching number from the given options.

Let’s solve this step by step.

We are given base-10 blocks:
- 1 cube = 1
- 1 long (rod) = 10
- 1 flat (square) = 100

---

First Problem:

Look at the first box:

- There are 3 flats → 3 × 100 = 300
- There are 5 longs → 5 × 10 = 50
- There are 2 cubes → 2 × 1 = 2

Add them: 300 + 50 + 2 = 352

So, the correct answer is 352

---

Second Problem:

Look at the second box:

- There are 5 flats → 5 × 100 = 500
- There are 7 longs → 7 × 10 = 70
- There are 6 cubes → 6 × 1 = 6

Add them: 500 + 70 + 6 = 576

So, the correct answer is 576

Final Answer:
352
576
