To make a birthday hat, draw a semicircle on construction paper, cut it out, then align the straight edges together (overlapping slightly) to make a cone-shaped hat. Glue or staple the edges together, and decorate the hat with paper circles or other birthday decorations.
- Assemble the materials
You need construction paper, white glue, scissors, a pencil, a stapler, a ruler and a compass.
- Draw and assemble the cone
Sketch a semicircle on a piece of construction paper, using a compass. For a birthday hat, an 8-inch radius should be sufficient. Cut out the semicircle, and bring the two straight edges together to form a cone. Try on the hat, adjusting the overlap of the edges to fit, then staple to hold it together.
- Complete the hat
Apply glue to the straight edges, and remove the staple when the glue is dry. Decorate the hat with pictures or construction paper cutouts.
