Subtopics to be covered:

- Define point, line, line segments, ray, plane

- Points -> Collinear, non collinear

- Types of lines -> parallel, perpendicular, concurrent, intersecting

Learning Outcome:

- Students can identify a geometrical concept from given set

- Students can classify the given set of geometrical concepts into categories

- Students can measure length of line segment from given information

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
