Achievement Objectives:

Achievement Objective: GM4-5: Identify classes of two- and three-dimensional shapes by their geometric properties.
AO elaboration and other teaching resources
Achievement Objective: GM4-6: Relate three-dimensional models to two-dimensional representations, and vice versa.
AO elaboration and other teaching resources

Purpose: 

The purpose of this activity is to engage students in evaluating a claim made on the basis of supporting statistics.

This activity may be carried out with step by step guidance, or by allowing the student to follow their own method of solution. The approach should be chosen in sympathy with students' skills and depth of understanding.

Activity: 

Pyroxenes are minerals found in cooled volcanic lava. They have an interesting geometric structure.

 

Identify and list the irregular polygons that make up the pyroxene crystal shown in the diagram.

 

Use this list to construct a net for a pyroxene crystal.
