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.
Ideal for the active classroom, this set contains 266 pieces of 7 different mathematical shapes (20 hexagons, 30 squares, 80 equilateral triangles, 12 pentagons, 40 right-angles triangles, 60 isocelese triangles and 24 large equilateral triangles) with 2 Polydron protractors. Enables you to build many types of nets, prisms, cuboids and pyramids and cover all the activities in the "Mathematics with Polydron" book (NM3044). Includes an exploring booklet and is packed in a sturdy case for easy transportation.
