In Games and warm-ups, Measurement and Geometry

Learning Objective:
Create and classify 3D shapes

Intended Outcome:
Identification of edges and vertices of 3D shapes

Materials:
Matchsticks or toothpicks, small blobs of blutak or marshmallows, or pieces of sticky tape
OR
3D shape building materials (K’nex, Connecta straws, Zometool)

Game Objective:
To create as many different 3D shapes as possible

Instructions:

  • For this game, students need to be organised into small groups
  • Roll the dice and collect that many edges (sticks) OR vertices (blutak). You can only collect one or the other on each throw, not a mixture of both
  • When you have enough edges and vertices, build a 3D shape. You can only build one of each shape (one cube, one tetrahedron, one square based pyramid…….)
  • Score 1 point for each edge and each vertex used in complete shapes and 5 points for each completed shape

Discussion Points:

  • What are the regular polygons?
  • What shapes can you make using the same size edges?
  • Which shape will give you the most points?
