Question

7.1 When we start teaching a concept to learners, we do not even need to mention the “big

name” for it. You will be surprised to see in the CAPS that we are actually teaching the

idea of polyhedrons in Grade 5 already. Visit CAPS and then draw up a lesson plan

introducing the idea or concept ‘Polyhedrons’ to a Grade 5 class, using those

polyhedrons which are prescribed for them.

7.1.1 Clearly describe what you are expected to do in the ‘before’, ‘during’ and ‘after’ stages of

the lesson taught using problem solving approach.

7.1.2 List 5 questions that you will pose to learners to trigger constructive discussions

Describe the manipulatives you will use for the lesson.

7.1.4 Design a worksheet and a memorandum.

Answer 1

7.1

Polyhedron - It is 3D shapes with flat polygonal faces, where polygons are the closed 2D figure bounded by more than 3 sides,staright edges and sharp corners.

7.1.1 I will firstly explain the concept of arising the polyhedron and then i will explain the basic elements of polyhedron

7.1.2 The five question which i will pose are following

(a) What are the elements of polyhedron?

(b) Draw 3 basic polyhedron.

(c)What is Eulers formula in polyhedron?

(d)Define diagonal of polyhedron

(e) Draw shape of cubic polyhedron

7.1.4

The plural of polyhedron is either polyhedrons or polyhedra.

We can derive relation between edges ,vertices
