Grades 1 and up. Explore plane geometry with these hands-on manipulatives. The 8 different lengths, each a different color, allow students to build angles and polygons of various sizes. This will enable students to study the heights of polygons, calculate areas, find center points, and more. By snapping 2 or more Geo Stix onto 1 of the 4 in. protractors, angle measurements can be calculated. The length of each Geo Stix, along with the length between each segment of the Geo Stix, is written on each Geo Stix. Includes 80 Geo Arms (8 each of red, brown, blue, and yellow, 12 each of dark green, purple, orange, and light green) and 2 protractors.
