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.
This set is ideal for group use in the classroom using 310 pieces including 160 Equilateral Triangles, 30 Hexagons, 80 Squares and 40 Pentagons. With storage container and booklet.
