Plastic arts and geometry

The resource that I'm going to introduce you today it is called HyperQBS by its author Andreas Hoenigschmid. 

This resource consists of cubes that are made up of 12 individual pyramids which are connected on their sides with magnets. Moving these triangles you can create different geometric shapes with a single cube. 

I believe that this resource it is a great educational  resource to teach 3D shapes in primary education. In this way, students can manipulate and create different solid shapes. Moreover, these cubes allow us to relational geometry and plastic arts. A good activity would be that students would create their own cube drawing different patterns.
