Drawing concentric circles
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.
