 UNDERSTANDING ELEMENTARY SHAPES

 

ACTIVITY –1. Types of Triangles

DATE:

 

AIM / Objective:

To understand of different type of triangles

 

MATERIALS REQUIRED:

Pencil, scale, eraser

 

PREREQUISITE KNOWLEDGE:

 

Concept of triangles

 

PROCEDURE:

 

Paste Ice-cream sticks to make 3 types of triangles based on angles.

Mention the names of triangles and their type in front of them.

 

Collect these things in the form of pasting papers (do real examples) and then measure their angle / sides.

ACTIVITY –4. Circle

DATE:

 

AIM / Objective:

To identify the parts of the circle.

 

MATERIALS REQUIRED:

Pencil, scale, eraser

 

PREREQUISITE KNOWLEDGE:

Concept of  circle

 

PROCEDURE:

(1)   Cut 3 different circles. Fold them and make crease to show diameter, segment and sector of circles.

 

For example:

 

(2)   Prepare a circular garden or stadium or tennis court or kabaddi ground. Mark the places of players, targets, audience etc. with respect to the diameter, radius,

 

centre of the circle chord, sector. Specify their positions with respect to the diameter, radius, centre, chord, sector of the circle.

 

 

LEARNING ASSESSMENT:

 

Show diameter, segment and sector of the circle.
