This 2-D polygons lesson plan also includes:
A hands-on activity uses the Zome modeling system, and helps young geometers either learn or review their knowledge of polygons. Learners build as many different 2-dimensional polygons as possible: triangle, square, rectangle, pentagon, hexagon, decagon, etc. and record information about their work on a chart. This activity can be extended to include types of triangles such as isosceles, scalene and equilateral.
