1. Polyhedron Inspired Art! Manpreet Dhinsa EDCP301 110

2.  A 3-dimensional geometric solid with flat faces, straight edges, and sharp corners  Word comes from Classic Greek where poly = “many”, hedron = “base” or “seat”  Plural form: polyhedra or polyhedrons What exactly is a polyhedron?

3. Polyhedron Examples Hexahedron Tetrahedron OctahedronDodecahedron Octagonal Prism Small Stellated Dodecahedron Great Cubicuboctahedron Icosidodecahedron

5. Altered Polyhedron (rhombus)

6. Materials Materials: Rhombus template tracer Pencil Construction paper * Scissors * You can substitute construction paper with a variety of other materials (e.g. regular paper, cardstock, aluminum foil, plastic, etc.)

7. Procedure 1.Using the tracer, trace out 30 rhombus shapes on to construction paper. 2.Cut out 30 rhombus shapes carefully. It is important to have all shapes the same size. 3.Immediately after cutting, place a dot on the backside of the shape. 4.Assemble all 30 pieces together by “hooking” pieces together in groups of 3 or 5. Group of 3 Group of 5

8. Adaptations & Extensions For younger grades: Create a collaborative class polyhedron Students individually design their rhombus shape Teacher assembles it together Extend the activity: Create recycled art, lamps, ornaments, etc.
