Frameworks is an open-framed building system which perfectly complements Polydron in that the shapes are interchangeable and they use a similar unique clip hinge which can be fixed together, edge to edge.

Its unique design features allow the child to see through individual shapes and models. Through the “Windows”, students can investigate shapes and angles, edges and vertices. For the more advanced student they can look deeper into the mathematical concepts such as angles, planes and tangents.

460 pieces made up of the 8 Frameworks shapes. Build structures and geometric solids that will allow students to appreciate their internal construction and spaces. Great for any classroom. This pack contains 160 Equilateral triangles, 40 Isosceles Triangles, 80 Right Angle Triangle and 20 Root 2 Triangles, 80 Squares, 20 Rectangles, 40 Pentagons, and 20 Hexagons. Packed in a storage container and includes an exploring booklet.
