Polydron Frameworks Class Set

310 open-frame pieces — triangles, squares, pentagons and hexagons — for building structures you can see straight through.

Frameworks show the skeleton of a shape rather than its surface, which is a different kind of understanding. Build a dodecahedron in solid panels and it's a ball; build it in Frameworks and it's a cage you can look into.

Suitable from age 6. Exploring booklet included.
