INTERACTION PROCEDURE EXPECTED PUPIL RESPONSE
Introduction
Teacher asks what is 6-4?
Also what is 4-6?
Is 2-3 = 3-2?
We studies the above said facts in VII class.
Today , we will study a new concept.

-2
No
3. Before that shall we play a game?
Activity
Teacher divides the class into 6 groups.
Teacher presents a box of bangles.
The bangles are shuffled and kept inside the box.
Teacher says :
I will give the box to each group, you have to take a bangle from the
box, without looking. There are 3 chances for each group.
If you take a green one, you will get 10 points and if you take a red
one you will lose 5 points.
Shall we start?
Teacher presents a chart.
Yes
Students actively listens to teacher.
Students actively take part in the
activity
Students fill the chart

How will you find the points of each group?
Suppose, group I took G G R
G = 10
G = 10 + 10 = 20 points
R = 20 – 5 = 15 points
Total = 15 points
Now group II took R R G
A red bangle = -5 points
When another red bangle is taken,
-5 + -5
= - (5+5) = -10
And then a green bangle ,
= -10 + 10 = 0
We write 5 + 5 = 2 X 5 right?
So,, what is -5 + -5 = ?
-5 + -5 = 2 X –(5)
= -10
10
20 points
15 points
Students listens to the teacher
-10
5. Now what is 3 X (-5)?
= (-5) + (-5) + (-5) = -15
Did you got the concept?
3 X (-5) = - (3 X 5)
= -15
Now what is 4 X -5=?
-(4X5) = -20
Enrichment activity
Find (-4) X (5) X (4) ?
Review
What is 4 X (-5) =?
What is 7 X (-2) =?
