& Division : VIII
Name of School : Strength :
Subject : Mathematics Duration : 45’
Unit : Area
of Quadrilaterals Date : 14.06.2014
Topic : Area of a parallelogram
Curricular Statement
Students
understand the properties of a parallelogram and the formula for finding its
area. They apply their knowledge to find out the area of parallelograms.
Content Analysis
Terms :
Parallelogram, triangle,
area, congruent, diagonal, height, base
Facts :
1) Opposite sides of a parallelogram are parallel.
2) Opposite sides of a parallelogram are
equal.
3) Diagonal divides a parallelogram into two
equal triangles.
4) Area of a
parallelogram is the sum of area of those two equal triangles.
Concept : Area of
a Parallelogram
Formula : Area of
a parallelogram = product of base and height
=
b x h
b
– length of a side, h – length of a side to its opposite side
Process : We can
divide a parallelogram into two triangles by drawing a diagonal. By adding the
area of these two triangles we get the area of a parallelogram.
Learning Outcome
Remembering:
recalls the information about quadrilaterals, parallelogram and their
properties

Introduction
To test the previous knowledge of the students teacher shows models
of triangles and asks some questions:
1)
What are the
properties of a triangle?
2)
What is the
formula for finding the area of a triangle?
Teacher now divides the students into groups and give model of two
congruent triangle to each group and ask to check whether the given triangle
are congruent or not.
