The idea of the set is that children can explore the properties of solid shapes by constructing them using framework pieces. Polydron sets are very child friendly and the teacher's guide and instruction sheets are very user friendly.
The children really enjoyed making the shapes and it was interesting to examine the names of shapes to discover their properties, e.g. the cuboctahedron.
After constructing the shapes we experimented with them, adding faces to augment and removing faces to diminish. They enjoyed making snub shapes where solids 'explode' and spaces are filled with triangles.
I'm certain that the children will remember the lessons and the properties of the shapes.
