The Connecting GeoStix set provides a hands-on approach to learning plane geometry. Students can explore concepts such as perimeter, area, shapes, spatial reasoning, and more through this versatile set. The 82-piece set includes GeoStix in various lengths, protractors, and double-sided activity cards for comprehensive geometric exploration. Features 80 color-coded straight sticks in 8 lengths (1in to 6in) marked in cm Includes 2 transparent protractors to measure angles Comes with 24 double-sided activity cards with interactive lessons on geometry Activity cards are laminated for easy note-taking with dry erase markers Students can create shapes like triangles, squares, and polygons with the GeoStix Supports learning of parallel lines, bisectors, transversals, and angle classification Ideal for teaching perimeter, area, and the Pythagorean Theorem Perfect for students in grades 3 and up, aligning with Common Core Standards
