2. CLASSROOM INTERATION PROCEDURE EXPECTED PUPILS RESPONSE
INTRODUCTION
ACTIVITY - 1
(i) What is an equation?
(ii) What is the form of an equation?
By asking these questions the teacher
leads the students to the topic
PRESENTATION
ACTIVITY - 2
Teacher provides a problem. Three
books of the same price and a pen for five rupees
were bought for thirty five rupees. What is the
price of one book?
Teacher asks the pupils
What is to be find out?
What is given?
Teacher explains the method to solve it
Let x be the price of one book
3 x + 5 = 35
3 x = 35 - 5
x = 30/3 = 10
ACTIVITY – 3
Teacher divide pupil into groups and give
an activity card containing the problem “four
chairs of the same price and a table for 3150
rupees were bought for 4950 rupees. What is the
price of a chair?
Some pupil answer correctly
Almost all pupils responded actively.
Pupil understand and write down
All groups solved the problem correctly

3. ACTIVITY - 4
Teacher provides a problem “The perimeter
of a rectangle is 20 centimeters; and its length is 2
cm more than the breadth. What is the length of
each side?
Teacher asks pupils
What is to be find out?
What is given?
Let x be the breadth of the rectangle
What is the length?
Length = X + 2
Perimeter = 20 cm
2 ( l + b ) = 20
2 ( X + 2 + X ) = 20
2 ( 2X + 2 ) = 20
4X + 4 = 20
4X = 16
X = 4 cm
Breadth = 4 cm + length = 6 cm
CLOSURE
ACTIVITY –5
Teacher concludes the class by saying about
above problems.
REVIEW
ACTIVITY – 6
Teacher asks some questions about above
problems and equations.
FOLLOWING ACTIVITY
In a box there are black and white beads. The
number of black beads is eight more than the
number of white beads; and the total number of
beads is four times the number of white beads.
How many black and how many white beads are
there in the box?
Almost all pupil respond actively
Pupil says that length = X + 2
Pupil responds actively
