3D Figures




G-O Frames

One of my favourite tools for investigating geometrical relationships is Polydron, G-O Frames, or Connexion – all names for similar products.   These let students construct and manipulate 3D figures, and investigate the relationships between 2D shapes and 3D solids.


Let’s Build

These cards give various criteria for building a 3D shape, from beginner to fairly advanced.  While ideal for 3D building materials, students could used wooden solids or diagrams to narrow down the correct figure.

Let’s Build Cards – new

New Let’s Build cards.  Slightly easier than above.

Polydron Party

This is a game where students draw cards, in turn, and attempt to construct a 3D figure from G-O frames.
