2nd Grade Place Value Worksheet: Count Blocks Up to Hundreds

This worksheet is designed to help students understand place value up to hundreds using base-10 blocks. The task involves counting the number of blocks in each set and writing down the total number. Here's how to solve each problem step by step:

Base-10 Blocks Recap:

- Large square blocks (flats): Each represents 100.
- Long rectangular blocks (rods): Each represents 10.
- Small square blocks (units): Each represents 1.

Solution for Each Problem:

#### 1)
- Flats: 1 (100)
- Rods: 3 (30)
- Units: 0
- Total: \( 100 + 30 + 0 = 130 \)

#### 2)
- Flats: 2 (200)
- Rods: 0
- Units: 4 (4)
- Total: \( 200 + 0 + 4 = 204 \)

#### 3)
- Flats: 1 (100)
- Rods: 4 (40)
- Units: 5 (5)
- Total: \( 100 + 40 + 5 = 145 \)

#### 4)
- Flats: 2 (200)
- Rods: 1 (10)
- Units: 2 (2)
- Total: \( 200 + 10 + 2 = 212 \)

#### 5)
- Flats: 0
- Rods: 0
- Units: 5 (5)
- Total: \( 0 + 0 + 5 = 5 \)

#### 6)
- Flats: 3 (300)
- Rods: 7 (70)
- Units: 0
- Total: \( 300 + 70 + 0 = 370 \)

#### 7)
- Flats: 3 (300)
- Rods: 3 (30)
- Units: 5 (5)
- Total: \( 300 + 30 + 5 = 335 \)

#### 8)
- Flats: 4 (400)
- Rods: 2 (20)
- Units: 3 (3)
- Total: \( 400 + 20 + 3 = 423 \)

Final Answers:

1. 130
2. 204
3. 145
4. 212
5. 5
6. 370
7. 335
8. 423

Boxed Final Answer:

\[
\boxed{130, 204, 145, 212, 5, 370, 335, 423}
\]
