TOPIC:-
Chapter:- 9 : Areas of Parallelograms and Triangles
DURATION:-
This
lesson is divided into seven modules and it is completed in seven class
meetings.
PRE-
REQUISITE KNOWLEDGE:-
Concept
of parallelogram chapter 8 class IX
Congruency
of triangles and concept of medians.
TEACHING
AIDS:-
Green
Board, Chalk, Duster, Charts, smart
board, projector and laptop etc.
METHODOLOGY:-
Demonstration
and Lecture method
OBJECTIVES:-
- Introduction and the concept of congruency of two figures.
- Concept of two figures on the same base and between the
same parallels.
- Theorem(Prove) Two parallelograms on the same base and
between the same parallel are equal in area.
- Theorem (Motivate) Triangle and parallelogram on the same
base and between the same parallel are equal in area.
- Theorem(Motivate) Triangles on the same base and between
the same parallel are equal in area.
- Diagonal of a parallelogram divide the parallelogram into
two triangles of equal area.
- Median of a triangle divide the triangle into two
triangles of equal area.
PROCEDURE
:-
Start the session by checking the previous knowledge of the
students, by asking the questions about the different types quadrilaterals and
their properties. Now introduce the topic polynomial step by step as follows.

|
1
|
Introduction : Explain different types of quadrilaterals and their properties. Also recapitulate the concept of congruency of two figures specially triangle and quadrilateral.
|
|
2
|
Now explain the concept of two figures on the same base and between the same parallels with the help of some examples.
|
|
3
|
Now give complete proof of the theorem : Parallelograms on the same base and between the same parallel are equal in area and help the students in the implementation of the theorem in different problems.
|
|
4
|
Now explain the theorem with poof : Triangle and parallelogram on the same base and between the same parallel are equal in area and explain the result by solving related problems.
|
|
5
|
Now explain the theorem with poof : Triangles on the same base and between the same parallels are equal in area and explain the result by solving some problems.
|
|
6
|
Now explain the result that : diagonal of a parallelogram divide the parallelogram into two triangles of equal area.
|
|
7
|
With the help of certain examples explain the concept that median of the triangle divide the triangle into two triangles of equal area.

EXPECTED
OUTCOMES:-
After studying this lesson students will be able to find the figures on the same base and
between the same parallels. Students should be able to use the results of
important theorems in different problems.
STUDENTS
DELIVERABLES:-
Review questions
given by the teacher. Students can prepare presentation on different results of
the theorems and some other important results used in the chapter. Solve NCERT
problems with examples, solve assignment given by the teacher.
EXTENDED LEARNING:-
ASSESSMENT
TECHNIQUES:-
Assignment sheet will be given as home work at the end of the topic. Separate sheets which will include questions of logical thinking and Higher order thinking skills will be given to the above average students.
Class Test , Oral Test , worksheet and Assignment. can be made the part of assessment.
Re-test(s) will be conducted on the basis of the performance of the students in the test.
