Busy Children are making platonic solids
and learning about how the number of triangles at a vertex determines its
shape.
Taping a cube on the outside of a stella
octangula shows how we can make a cube out of equilateral triangles.
Turn stop game is a fun way to investigate the rotational symmetries of polyhedra. The polyhedra is rotated from an initial position until it reaches the point where it looks the same and everyone shouts 'Stop!'
Looking at duality by comparing the cube on the outside of the stella octangula with the octahedron within.
Looking through an octahedron. Eva examines
our prototype triangles forming an octahedron that casts a regular hexagonal
shadow.
Making icosahedra. The children are in three teams, each responsible for their own plan for coloring the icosahedron and organizing themselves to turn it into reality.
Inside the endopentakis-icosi-dodecahedron.
The triangles are on tour in Kansas at a conference for links between art
mathematics and science.
