Section 2: Write each number in standard form.

#### Instructions:
Convert the visual representation of base-10 blocks into standard numerical form.

#### Solutions:

1. a.
- The image shows 7 cubes (each representing 1000) and 1 rod (representing 10).
- Total: \( 7 \times 1000 + 1 \times 10 = 7000 + 10 = 7010 \)
- Standard form: 7010

2. b.
- The image shows 6 cubes (each representing 1000), 2 rods (each representing 10), and 3 units (each representing 1).
- Total: \( 6 \times 1000 + 2 \times 10 + 3 \times 1 = 6000 + 20 + 3 = 6023 \)
- Standard form: 6023

3. c.
- The image shows 9 cubes (each representing 1000), 1 rod (representing 10), and 2 units (each representing 1).
- Total: \( 9 \times 1000 + 1 \times 10 + 2 \times 1 = 9000 + 10 + 2 = 9012 \)
- Standard form: 9012

4. d.
- The image shows 8 cubes (each representing 1000), 1 rod (representing 10), and 5 units (each representing 1).
- Total: \( 8 \times 1000 + 1 \times 10 + 5 \times 1 = 8000 + 10 + 5 = 8015 \)
- Standard form: 8015
