This interactive version of the Great Dodecahedron was inspired by a Mathematical Association Poster.
Invite the learners to look at the
picture an describe what the can see. They are not allowed to use their
hands to point but must describe any shapes they can see in the picture so
that the rest of the class can understand what they are describing. Some
children might describe 2D shapes while others will see 3D.
There are six buttons at the bottom of the picture (if Flash is enabled) but these should only be used by the teacher as a last resort if a child can't easily see some of the shapes which might be described or who need a little help to get started. The buttons, from left to write show:
1. The Great Dodecahedron
4. Pentagon and Starfish!
1. Great Dodecahedron (twelve intersecting pentagonal faces)
2. Great Icosahedron (twenty intersecting triangular faces)
These models are on display in London's Science Museum
