Drawing concentric circles, with this hands on activity circle as a shape and variations in it is explored.

Objectives

The students learn that concentric circles are circles with same centre but different radii.

Estimated Time

15 minutes

Prerequisites/Instructions, prior preparations, if any

The students should have the skill of drawing circles accurately for given radius.

Materials/ Resources needed

White paper, compass, pencil, colour pencils, scale

Process (How to do the activity)

What is the centre for differrent circles.

Evaluation:

Are the students able to understand that the centre is same for concentric circles.

Question Corner:

What are equal circles (congruent)?
What determines the size of the circle ?
Give examples for objects similar to concentric circles.
