Learning Resources' AngLegs come in six lengths that easily snap together to motivate students to explore plane geometry on their desktop or the overhead projector. Students will discover what happens as they use the same length legs verses different length legs to build various polygons, attach additional legs to study polygon heights, calculate areas, find center points and more. Snap two AngLegs onto the protractor to explore angles, add a third leg for triangles, a forth for quadrilaterals, and so on. Includes 72 AngLegs (12 each of six different lengths in six colors), two snap-on protractors, and a set of 15 activity cards, for grades K-2, 3-5 and 6-8. All activities adhere to the NCTM Standards for geometry.
