A set of 9 geometric solids which are made of different materials, have different surfaces and make different sounds.
The set is placed in a package with spaces fitted for each solid.
There are 9 geometric solids in a set: a sphere, a regular triangular prism, a cone, a regular rectangular prism, a regular tetrahedron, a cube, a cylinder, a regular triangular pyramid, a regular rectangular pyramid.
Using the sense of touch, a child can identify a particular geometric solid, discern different materials (plexiglass, wood, metal) and textures, and fit the solid to the figure in the package. The textures of the solids and the sounds they make are to be associated with the material of which a solid is made.
A teaching aid, which helps in the development of a blind or a half-blind child while they play in the assistance of their carer, stimulates the children’s sensory development, haptic and auditory abilities, as well as manual ability.
