Lesson Plan

[Author - Kripa S]

Objective: Introduce Polygons, explain Quadrilaterals, types and properties

Subtopics to be covered:

- Identify polygons and classify based on number of sides

- Classify polygons (convex, concave, regular, irregular)

- Sum of angles of a polygon

- Types of Quadrilaterals and their properties (Trapezium, Kite, Parallelogram, Rhombus, Rectangle, Square)

Learning Outcome:

- Students can classify polygons and quadrilaterals

- Students can define types of quadrilaterals

Activities

[Author - Kripa S]

1. Make teams of 6 students. One team will explain what is interior and exterior of a closed curve (all students stand in a circle seeing inside for interior and outside for exterior). Another team will explain what is convex and concave polygon (they'll stand to make a polygon of that shape). One group will show the difference between regular and irregular polygon (the students will stand at equidistant positions, or near and far away).

2. Make two teams. One team will draw a polygon on board and other will guess what it is. Play for 10-15 times and add the score to find the winning team
