Answer to Question #230251 in Geometry for Bongane Masilela

Question

You are doing the topic: Polyhedra with your Grade 9’s in Term 3. How can you 

teach this concept in a dialectic, empirical and rational way, all in the same lesson?

Answer 1

Polyhedra are three-dimensional shapes with finite faces.

Dialectic- here we will have an introductory discussion about the characteristics of polyhedra.

Empirical- in this stage we will observe different shapes of polyhedra including prisms.

Rational- in this last stage we will try to understand on how to find surface area and volume of the polyhedros using different formulas.
