Back To School Math Mystery Pictures - Free Printable

You're working on a “School Mystery” Addition Color-by-Number worksheet. The goal is to:

1. Solve the simple addition equations listed at the bottom.
2. Match each answer to a color (yellow, blue, green, black).
3. Color the squares in the grid that contain those numbers with the corresponding color.
4. When you’re done, a mystery picture (likely school-themed) will be revealed!

✔ Step 1: Solve the Addition Equations

Let’s solve each equation:

#### 🟡 Yellow:
- `2 + 5 = 7`
- `3 + 5 = 8`

→ So, color all squares with the number 7 or 8 yellow.

#### 🔵 Blue:
- `3 + 1 = 4`
- `8 + 2 = 10`

→ So, color all squares with the number 4 or 10 blue.

#### 🟢 Green:
- `4 + 2 = 6`
- `3 + 2 = 5`

→ So, color all squares with the number 6 or 5 green.

#### ⚫ Black:
- `7 + 2 = 9`

→ So, color all squares with the number 9 black.

✔ Step 2: Apply Colors to the Grid

Now go through the grid and color each cell based on its number:

- Yellow (7 or 8) → Fill in all cells with 7 or 8.
- Blue (4 or 10) → Fill in all cells with 4 or 10.
- Green (5 or 6) → Fill in all cells with 5 or 6.
- Black (9) → Fill in all cells with 9.

> 💡 Tip: Look for the diamond-shaped areas — they contain 9s, so they’ll be black. Also, notice the “7” and “6” in the triangles — those will be yellow and green, respectively.

✔ Step 3: Reveal the Mystery Picture

Once you’ve colored everything correctly, you should see a school-themed image emerge — possibly a school bus, backpack, pencil, or apple — depending on how the numbers are arranged.

Looking at the grid, the black diamonds (with 9s) and the triangles with 7 and 6 suggest it might form something like a schoolhouse or school bus with windows and wheels.

🧠 Final Answer Summary:

| Color | Numbers to Color |
|--------|------------------|
| Yellow | 7, 8 |
| Blue | 4, 10 |
| Green | 5, 6 |
| Black | 9 |

✔ Just color the grid according to this key — and the mystery picture will appear!
