Learning with RHOMBO

 

 

RHOMBO blocks are ideal for teaching
   mathematical and geometric ideas
     in the classroom.


Geometrical concepts
   are easy to comprehend
     when handling a real
       three-dimensional model.

Some concepts that can be demonstrated with RHOMBO blocks:

  • Points, lines & planes
       in three dimensions.
     
  • Areas & volumes.
     
  • Orthogonal projection
       onto a plane or a line
     
  • Angles between lines and
       between planes
     
  • Fundamental symmetries
     
  • Lattices, vectors and coordinates.
  • Vectors in two & three dimensions
     
  • Parallel lines and planes
     
  • Projections from spaces of higher dimensions
     
  • Polyhedra and their
     stellations
     
  • The Golden Ratio
     
  • New quasi-crystal forms
