Activities
[Contributor - Kripa S]
1. Share examples of point, line segments, circle from daily life. (example: star, bat, tubelight, side of a fan, bindi, dosa, chapathi etc)
2. Share example of rays (torch light, sun rays, etc )
3. Make different closed shapes using 6 pens or sticks. Reduce the sides by 1 everytime and make a new shape. What happens when you have 2 sides, what closed shape can you make? Is it possible? Discuss and understand what is the minimum requirements for a polygon/ closed shape
