Solve one-step equations to reveal the hidden picture in this engaging math activity.

Problem Description:

The task involves solving one-step equations and using the solutions to color a grid, which will reveal a hidden picture. The equations are provided in the key at the top of the worksheet, and the grid contains numbers that correspond to the solutions of these equations.

Step-by-Step Solution:

#### 1. Solve the Equations in the Key:
We need to solve each equation and assign a color to its solution.

- Pink Square (5 + 2 = ?):
\[
5 + 2 = 7
\]
So, 7 corresponds to the pink square.

- Blue Square (2 × 3 = ?):
\[
2 \times 3 = 6
\]
So, 6 corresponds to the blue square.

- Black Square (8 ÷ 2 = ?):
\[
8 \div 2 = 4
\]
So, 4 corresponds to the black square.

- Light Pink Square (4 - 1 = ?):
\[
4 - 1 = 3
\]
So, 3 corresponds to the light pink square.

- Lighter Pink Square (3 × 3 = ?):
\[
3 \times 3 = 9
\]
So, 9 corresponds to the lighter pink square.

- Dark Pink Square (8 + 0 = ?):
\[
8 + 0 = 8
\]
So, 8 corresponds to the dark pink square.

- Light Blue Square (2 + 3 = ?):
\[
2 + 3 = 5
\]
So, 5 corresponds to the light blue square.

- Lighter Blue Square (10 ÷ 5 = ?):
\[
10 \div 5 = 2
\]
So, 2 corresponds to the lighter blue square.

- Red Square (5 - 4 = ?):
\[
5 - 4 = 1
\]
So, 1 corresponds to the red square.

#### 2. Color the Grid:
Now, we use the solutions from the key to color the grid. Each number in the grid corresponds to a specific color based on the solutions we calculated.

- Number 2: Lighter Blue
- Number 3: Light Pink
- Number 4: Black
- Number 5: Light Blue
- Number 6: Blue
- Number 7: Pink
- Number 8: Dark Pink
- Number 9: Lighter Pink
- Number 1: Red

#### 3. Fill in the Grid:
Using the above color assignments, we color each cell in the grid according to the number it contains. Here is a breakdown of the process:

- Replace all 2s with Lighter Blue.
- Replace all 3s with Light Pink.
- Replace all 4s with Black.
- Replace all 5s with Light Blue.
- Replace all 6s with Blue.
- Replace all 7s with Pink.
- Replace all 8s with Dark Pink.
- Replace all 9s with Lighter Pink.
- Replace all 1s with Red.

#### 4. Reveal the Hidden Picture:
After coloring all the cells according to the numbers, the colored grid will reveal a hidden picture. This is the final step of the activity.

Final Answer:

The hidden picture is revealed after coloring the grid based on the solutions to the equations. The exact image depends on the pattern formed by the colored cells, but the process is complete once all cells are colored correctly.
