What is it?
It consists of a board based on a triangular frame with the pegs located at the vertices of equilateral triangles. The distance between each point and all points adjacent to it is the same.
The rubber bands are hooked on the pegs in such a way as to represent the different shapes and thus discover the relationship between surface and volume, deepen and understand the concepts of area and the geometric planes and associate concepts of geometry with algebra and calculus.
What does it develop?
– Provides the opportunity to explore a large number of shapes at a specific level, while exercising fine motor skills and muscle coordination.
– Allows the formation, transformation and cancellation of shapes very quickly by modifying only the support points of the rubber bands.
– It favours the acquisition of concepts based on the observation of the created shapes.
– The possibility of orienting the board from different angles makes it possible to recognise what is represented from different perspectives.
– Encourages creativity, since it facilitates personal research.
Who is it for?
Its optimal use occurs in the third cycle of Primary Education.
How is it used?
– Free construction: use of rubber bands to develop designs and work on fine motor skills.
– Representation of geometric shapes: use rubber bands to work on plane geometry and basic mathematical processes: scaling, shifting, symmetry, etc.
– Representation of basic 3D geometric shapes such as cubes, parallelipeds or pyramids.
– Discovery of the 3D shapes by building their plans: starting from given shapes, you can make their 3D representation by building each of the sides with the rubber bands.
– Discovery of 3D shapes based on their perspectives: the most fun and complex application is to discover a three-dimensional figure based on its plan, elevation and profile views.
