Introduction :
Teacher recalls about negative numbers and
ask the students can you tell me what is 9-4
So you are familer with the subtraction
of positive numbers.
Today ,we are going to learn the subtraction
of negative numbers using number line and
to teach this I need your help for an activity
involving students to represent number line.
Presentation:
Teacher gives instruction about the activity
Teacher draws the line using chalk on the
ground and marks an approximate midpoint
to do note Zero(0) on the numbers line
Teacher calls two Students and ask them to
stand at the Zero position.The side is
negative side.
Teacher asks to class to say a number and
the student 1 and 2 are moment that amny
steps to the left for –ve numbers and right for
the numbers.
Student say immediately
‘5’
Students are ready for the activity
Students volunteer and take their position.

3. Initial position
0 Student 1
Student 2
Students say number(-5) to the left
-5 0
0 student 1
Another students says 3 to the left (-3)
Teacher asks what symbol should be given
final position
-2
Student 1 0 3 0
-5 Student 20
Can you tell me how we can write this as
a statement?
Teacher appreciates
From the movement of the students can you
tell me difference in their position
If they are in the left side what symbol
should be used?
Teacher appreciates and says we arrine at
the answer
Students moves 5 steps to the left
Students moves 3 steps to the left
Student says ‘ - ‘ Sympol
Students say
-5-(-3)
2 steps
Students say minus
So answer is -2
Students understand the subtraction

4. -5-(-3) = -5+3= -2
We can also say - x - = +
Application : (Eg:1)
Teacher writes a question on the board
-8-(-4)
Teacher gives the solution on a number line
-8 -7 -6 -5 - 4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9
(Eg:2)
Que:-7-(-2)
Teacher gives the question and ask the
student to final the answer
Recap of the session
Students understand the concept of number
line and subtraction of negative number.

-8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4
Teacher ask the student about how two negative number can be subtraction and the
students explain the procedure they have learn
Teacher appreciates
Home assignment:
Teacher gives the following as home work
(a) -6-(-4)
(b) -8-(-5)
