**INTRODUCTION**

A net is a pattern made from two dimensional shape to form three dimensional shape.

**THE NETS OF PRISM **

The net of a prism consists of six faces.

Focus prisms are triangular, square and rectangular prisms.

NET OF TRIANGULAR PRISMThe net of a triangular prism consists of two triangle with three squares or rectangles.

NET OF SQUARE PRISMThe net of a square prism consists of six squares.

NET RECTANGULAR PRISMThe net of a rectangular prism consists of two squares and four rectangles.

Rectangular prism is also as cuboid.

MAKING OF PRISMMaterials Needed are cardboard, pencil, ruler and gum.

1. Draw the nets of cube and cuboid.

2. Use the nets to make cube and cuboid.

**NET OF SQUARE PYRAMID**

The net of a square pyramid consists of one square and four triangles.

NET OF TRIANGULAR PYRAMIDThe net of a triangles pyramid consists of four triangles.

One of the triangle is a base.

NET OF RECTANGULAR BASE PYRAMIDSThe net of a rectangular pyramid consists of one rectangle and four triangles.

MAKING OF PYRAMIDSMaterials Needed are cardboard, pencil, ruler and gum.

1. Draw the nets of square, triangular and rectangular pyramids.

2. Use the nets to make square, triangular and rectangular pyramids.
