Create a decorative holiday ornament while reinforcing knowledge of geometric properties.
- Create a decorative holiday ornament
- Identify the geometric properties of a 3-D square pyramid, including faces, edges and vertices
Before You Start: Gather materials needed: Foam or tag board to cut the pyramid shapes from, pipe cleaners, pom-poms, ribbon, glue and tape.
Let's Get Started! Step 1. Cut out a square and 4 identical triangles from the foam or tag board. The triangles should have a side that is the same length as the sides of the square. More-advanced students can try to create a "net" from a single piece of foam or tag board that will simply fold together to form the square pyramid.
Step 2. Use glue or tape to put together the square pyramid. Hot glue may work best for this step, but be sure to do so carefully with adult supervision.
Step 3. Decorate the ornaments using pipe cleaners along the edges, pom-poms at the vertices (corners) or anything else you like.
Step 4. Attach a loop of ribbon and hang!
Furthermore: As you are making your ornaments, discuss with the students the different attributes of a pyramid. Encourage them to discuss the attributes with their families after taking their ornament home.
