# Halloween Pumpkin Design Ideas that Support Math Learning

• Decorating jack-o’-lanterns offers opportunities for children to explore early math concepts like shape, size, and measurement.
• You can do this activity with things commonly found at home and in classrooms — no pumpkin required.

# Step 2: Create an assortment of shapes.

• Size. What will fit on your pumpkin?
• Number. How many triangles will we need to make the eyes and nose?
• Estimation. About how many triangles do you think we will need to make a mouth out of triangles?

# Step 3: Design the jack-o’-lantern face.

• Shape. What shape should we use for the nose?
• Shape attributes. These rectangles are different. How come they are both rectangles?
• Distance. How far apart should we place the eyes?
• Spatial relations. The nose goes in the middle of the pumpkin. The eyes are above the nose. If we rotate the shape, the nose looks different.
• Size. Is the nose triangle bigger or smaller than the triangles we used for the eyes?
• Number. How many squares will fit where we want to make the mouth?

# Step 4: Enjoy and talk about the designs.
