Curricular  Statement

It enable pupil  to understand the concept of polygons.

Content  Analysis

Terms : polygons , pentagon , Hexagon , Octagon , Nonagon , Decagon.

Facts :   Closed figure having more than 2 sides are called polygons.

               Closed figure having  5 sides are called Pentagon.

               Closed figure having  6 sides are called Hexagon.

               Closed figure having  8 sides are called Octagon.

               Closed figure having  9  sides are called Nonagon.

                Closed figure having  10  sides are called Decagon

Learning  Outcome

The pupil will be able to

·       Understand the concept of polygons.

·       Identify  the concept of polygons.

·       Apply the concept in new situations.

·       Answer the questions based on the concept.

·       Analyse  the concept of each polygons.

Pre-Requisites

·       Basic concepts on Geometrical Shapes.

·       Concepts of sides and vertices.

Teaching-Learning Resourses

·       Models of different polygons made of thermochol.

·       Common classroom aids.

                                                                         

                 

               

Classroom interaction procedure                           Teacher engages in a friendly talk with Pupil.Teacher  asks the following  questions to check the previous  knowledge of students. Name some geometrical shapes                              Teacher shows a model contain- Ing different types of polygons Teacher asks the following Questions showing the model. Pointing to the triangle teacher asks about the figure.               Similarly ,teacher shows figures of     quadrilateral                 Teacher showing the figure of pentagon, hexagon, heptagon ,octagon Then teacher asks to observes the common properties of the figures, regarding the sides ,closure etc… Teacher asks pupil to draw figures having 9 and 10 sides. Teacher named them as nonagons and decagons .Then teacher asks to give a common name to these figures  Teacher explains ,since the figures have more than 2 sides ,they are called polygons                                                                          Review and Application Teacher repeates the definition of the polygons Closed figures having three or more than three sides are called polygons. Teacher asks pupil to read the definition on text and give some examples ofpolygons.

Expected pupil response Triangles,rectangles,square Pupil closely observes the figure                             Pupils to say about the figure.                             And say that is a triangle and                                                                                           describes about the figure ,ie ,it                                                                                    had three vertices,three sides.   pupil analyse the properties of Quadrilateral                                                           pupil closely observes all the properties of each figure and discuss among themselves. Through discussion pupil arrive at following conclusion, All these figures have more than 2 sides,and the figures are closed. Pupil tried to draw and did it with the help of teacher Students in silence. Pupil carefully lissons. Pupil read the definition loudly and give many examples of polygons

Follow up activity

Draw different types of polygons and name them.
