Frameworks: platonic solids set

View item in the U of T Libraries catalogue

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. This set allows the student to build and explore the 5 Platonic Solids all at once.
