Explore plane geometry with these hands-on manipulatives. 
The eight different lengths, each a different color, allow students to build angles and polygons of various sizes. 
This enables students to calculate areas, find center points, and more. 
Calculate angle measurements by snapping two or more onto one of the 4 in. protractors. 
Length between each segment is written on each Geo Stix. Includes 800 Geo Stix (80 each of red, brown, blue, and yellow; 120 each of dark green, purple, orange, and light green) and 20 protractors.
