Polydron is a brand of building sets. Most of the sets by this manufacturer have frames or tiles as the main pieces. Magnetic tiles are common among the building sets, but the non-magnetic tiles are much rarer. Polydron, however, has many building kits with plastic flat polygons that connect without magnets. There are many types of geometrical building sets by Polydron, and Frameworks set is one of them.
The pieces of this set are ightweight frames thet connect by the edges. Theseedges are serrated and have special pins, so they easily snap together. This system works like a puzzle, allowing you to connect the frames at any angle you may need and create all kind of shapes.
The pieces of these sets are big – even the smallest of them are a few inches long. Because of this size and lack of any magnets, they are very safe to play with – though they may be too abstract for the smaller kids. They have different colors and shapes – triangles, squares, pentagons, hexagons, and so on.
These sets have almost no decorations or moving pieces like wheels, so the abstract geometric shapes are the specialty of Polydron. These sets are great for explaining kids mathematical concepts, so they can be used in schools.
