Using this book, students learn to draw stars with seven, eight, or more points, and formulate conjectures about their mathematical structure. They also assemble polygons into 3-D polyhedra and develop spatial intuition. Students develop a definition of star and find a procedure for drawing stars with seven, eight, nine, or more points. Students assemble equilateral triangles, squares, pentagons, hexagons, octagons, and decagons to form symmetrical 3-dimensional solids called polyhedra. The book provides blackline masters of polygons to photocopy onto colored paper. Students cut out the polygons, fold the flaps, and attach them with small staplers. Completed polyhedra make an attractive wall display. These activities meet four distinct NCTM standards.
