Autumn term started at Thornhill Primary with paper version of a fidget spinner:
the kaleidocycle.
What is a kaleidocycle?
The simplest kaleidocycle is a chain of an even number of tetrahedra. The tetrahedra are connected on perpendicular edges.
What makes it special is that you can continually twist it inwards or outwards while it shows different sides of each tetrahedron..
The 3dimentional object which develops is called a kaleidocycle
(greek: kálos [beautiful] + eîdos [form] + kyklos [circle]).
It is a ring of an even number of tetrahedra.
(Tetrahedra are pyramids with equal edges and equilateral triangles as sides.)
Children have constructed beautiful toys using templates and personalised them with their own designs.
Well done everyone!
