Elastic Geometric Soccer Ball

Supplies Used: Adhesive, Cardstock or construction paper, Rubber bands (#10 size)

The teacher will die-cut the materials for student use prior to the lesson.

1. All the Elastic Geometrics have 1" sides, allowing all the geometrics to fit together.
2. Die-cut 12 black pentagons and 20 white hexagons using cardstock for each soccer ball.
3. Fold on all the perforations.
4. Using #10 size rubber bands, attach the pieces together to form a soccer ball with the black pentagons surrounded by white hexagons (Main Photo).
5. The value of binding the sides with rubber bands is the ease with which the students can dismantle one shape and create new geometric shapes.
6. Adhesive may also be used on the tabs to construct the truncated icosahedron or other geometric shapes.
7. Discuss volume, perimeter and area with the students, counting vertices and edges.
