Objective: To understand the concept of perimeter of a closed figure.

materials required: A geoboard, strings of different colour and a ruler

Procedure:

Š Divide the class into pairs and choose any pair randomly.
Š Give a piece of thread to one partner and instruct him/her to make a square on

a geoboard as shown below.

Š Now, the other partner will remove the thread, hold the thread carefully from
both ends and measure the length of the thread with the help of a ruler as

shown below.

0 cm 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

0 1 2 3 4 5 6

Š The length of the thread will be the perimeter of the square.
Š Repeat the activity for different closed planes figures like rectangles and triangles,

etc. with different pairs of students.
Š Ask the pairs to make a shape of a given perimeter. Give points to the pair who

does it correctly.
