Free Halloween Math Worksheets - Free Printable

This worksheet is a Halloween-themed alphanumerical coordinates activity where you plot points on a grid using alphanumeric coordinates (like A0, B1, etc.) and color them according to the given color codes. The goal is to reveal a hidden Halloween picture by coloring the correct squares.

Let’s go through how to solve this step-by-step:

---

🔍 Understanding the Grid

- The grid has:
- Columns labeled A to P (horizontal axis).
- Rows labeled 0 to 16 (vertical axis).
- Each coordinate is in the format: [Letter][Number].
- Example: `A0` means column A, row 0.
- Example: `P15` means column P, row 15.

You’ll need to:
1. Locate each coordinate on the grid.
2. Color the square at that location with the specified color.

#### 🟢 GREEN
Coordinates:
```
I6, I7, I8, J3, J4, J5, J6, J7, J8, K4, K5, K6, K7, K8, K9, K10, L3, L4, L7,

N10, O7, O8, P8
```

> Likely the stem of the pumpkin — green area above the orange part.

---

#### 🟡 YELLOW
Coordinates:
```
A4, B5, F5, G10, H10, I12, K13, M5, M6
```

> Probably small details like highlights or glowing parts.

---

#### 🔵 GRAY
Coordinates:
```
A14, B3, B16, C3, F4, F10, G2, H0, H12, I10, J13, L13
```

> Possibly shadows or background elements.

---

#### ✔ WHITE
Coordinates:
```
A15, A16, B0, B15, C1, C2, C4, D6, E7, G3, G15,
H1, L9
```

> Could be highlights or background areas.

🧩 How to Solve It

1. Get a printed version of the grid or use graph paper.
2. Plot each coordinate one by one.
- For example, `A0`: go to column A, row 0 → mark it.
3. Color each point according to its assigned color.
4. As you fill in more points, a pumpkin (jack-o'-lantern) will emerge.

---

🎃 Expected Result

After plotting all points:
- The blue and black areas form the main pumpkin face.
- The green area forms the stem.
- Yellow may be for eyes or glow.
- White could be highlighted spots.
- Gray might be shading.

The final image should resemble a Halloween jack-o'-lantern with a carved face and stem.

✔ Final Answer:

👉 Plot all listed coordinates on the grid and color them as per the legend. The resulting image is a Halloween jack-o'-lantern.
