Objective: To introduce the different geometrical concepts
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
