Students solve subtraction problems to reveal a colorful robot in this engaging math activity.

Problem Description:

The image shows a math worksheet where students are tasked with solving subtraction facts and coloring the corresponding sections based on the provided color key. The goal is to solve each subtraction problem, determine the answer, and then color the section according to the color code.

Color Key:

- 0 = gray
- 1 = green
- 2 = gray
- 3 = green
- 4 = green
- 5 = gray
- 6 = green
- 7 = red

Steps to Solve:

1. Identify Each Subtraction Problem:
- The worksheet contains various subtraction problems (e.g., 8-2, 5-2, etc.) in different sections of the image.

2. Solve Each Subtraction Problem:
- Perform the subtraction for each problem to find the result.

3. Match the Result to the Color Key:
- Use the color key to determine which color corresponds to the result of each subtraction problem.

4. Color the Sections:
- Color each section according to the result of the subtraction problem it contains.

Detailed Solution:

#### Step 1: Solve Each Subtraction Problem
Let's solve all the subtraction problems shown in the image:

- Top Row:
- 8-2 = 6 → green
- 5-2 = 3 → green
- 5-2 = 3 → green
- 6-2 = 4 → green

- Second Row:
- 3-2 = 1 → green
- 7-2 = 5 → gray
- 3-2 = 1 → green
- 3-2 = 1 → green

- Third Row:
- 6-2 = 4 → green
- 7-3 = 4 → green
- 2-2 = 0 → gray
- 6-2 = 4 → green

- Fourth Row:
- 3-2 = 1 → green
- 6-2 = 4 → green
- 6-2 = 4 → green
- 6-2 = 4 → green

- Fifth Row:
- 5-2 = 3 → green
- 6-2 = 4 → green
- 5-2 = 3 → green
- 8-2 = 6 → green

- Sixth Row:
- 5-2 = 3 → green
- 5-2 = 3 → green
- 5-2 = 3 → green
- 8-2 = 6 → green

#### Step 2: Match Results to the Color Key
Using the color key:
- 0 = gray
- 1 = green
- 2 = gray
- 3 = green
- 4 = green
- 5 = gray
- 6 = green
- 7 = red

#### Step 3: Color the Sections
Based on the solutions:
- All results of 6 should be colored green.
- All results of 5 should be colored gray.
- All results of 4 should be colored green.
- All results of 3 should be colored green.
- All results of 2 should be colored gray.
- All results of 1 should be colored green.
- All results of 0 should be colored gray.

Final Answer:

After solving all the subtraction problems and applying the color key, the sections should be colored as follows:
- Green: Sections with results 1, 3, 4, and 6.
- Gray: Sections with results 0, 2, and 5.
- Red: No sections have a result of 7, so no red is used.

Final Colored Image:

The final image will have:
- Green: Most sections (results 1, 3, 4, 6).
- Gray: Fewer sections (results 0, 2, 5).
- Red: None.

Thus, the final answer is the completed and colored image based on the above steps.
