CLASSROOM INTERACTION PROCEDURE

PUPIL’S RESPONSE

INTRODUCTION       The teacher starts the class with the following riddle: Iam a two dimensional shape. Iam a closed figure. I have more than two sides I have equal number of edges and vertices. I have no adjacent sides as collinear. Can you tell who I am? Yes. Can you give me examples of polygons? PRESENTATION ACTIVITY The teacher shows the following innovative work model and explains how it was made and its purpose. The teacher now asks each student from a bench to demonstrate any polygon using a string. So you know all about the shapes of a polygon, isn’t it? Now let us learn about exterior angles of a polygon. APPLICATION The teacher distributes matchsticks and ask the students to make a triangle with it. Now can you extend all its sides using the given matchsticks. Can you measure all its outer or exterior angles slowly without shaking the arranged matchsticks? What is the sum of exterior angles of a triangle? The teacher now asks the students to find the sum of exterior angle of a quadrilateral. What is the sum of exterior angles of a quadrilateral? Yes. In the same way find out for pentagon also. What is the sum of exterior angles of a pentagon? REVIEW What did we learn today? So what is a polygon? What is the sum of exterior angles of any polygon?

Polygons Triangle, Quadrilaterals, Pentagon, Hexagon, Heptagon, Octagon, Nonagon, Decagon, etc. Triangle Quadrilateral Pentagon Hexagon Yes Yes 360 º It is also 360 º It is also 360 º Polygons and its exterior angles. A polygon is a closed 2- dimensional figure with atleast three sides. 360 º

FOLLOW UP ACTIVITY

·        Draw a picture of your choice using only geometrical shapes.
