===Process (How to do the activity)===
===Process (How to do the activity)===
* Draw circle with ‘circle with center and point’ or use the slider
* What do you notice, how is the circle formed.
What kinds of questions you can ask for that activity
* Which point is the centre of the circle ?
* Plotting points on the circle, connect these points to the centre of the circle.
* What can you say about the segment lengths?
* Measure the segment lengths to show they are equal.
* Establish center of the circle’ and ‘radius’
* Differentiate between circle and region enclosed by a circle.
* '''Evaluation:'''
# By what parameter is the size of a circle defined ?
# Bigger the radius, _____________
# How do you name a circle ?
# Can you draw a circle without knowing the radius ?
