Prerequisite
knowledge
![Page 6: integers maths ppt](https://reader035.fdocuments.in/reader035/viewer/2022081417/55808bdbd8b42a08768b4680/html5/thumbnails/6.jpg)
1) The collection of numbers with whole numbers
which is written as …,-3,-2,-1,0,1,2,3,… are called
integers. 2)The numbers 1,2,3,4,5,6,… are
positive integers.
3) The numbers-1,-2,-3,-4,-5,-6,… are negative
integers.
4) Positive integers are marked on right hand side of
the number line and negative integers are marked on
left hand side of the number line.

Procedure
![Page 15: integers maths ppt](https://reader035.fdocuments.in/reader035/viewer/2022081417/55808bdbd8b42a08768b4680/html5/thumbnails/15.jpg)
1) Take a pink graph paper and cut a strip of 10 squares from it. Start writing positive integers (including 0) from left to right on the squares .
2) Take a green graph paper and again cut a strip of 10 squares from it. Start writing negative integers from right to left on the squares.
3) Place a sheet on a table and draw a long line. Mark a point in the middle of the line and to the right side of that point, paste the pink graph strip of positive integers and to the left side, paste the green graph strip of negative integers. Make sure that both the strips are attached to each other.

4) If we wish to add a number, we will move to the right side and if we wish to subtract a number, we will move to the left side. A) To show 2 more than 3 Since we want to add, we will move to the right side. In the given example, we wish to add 2 to3. So, place the marker on 3 and move 2 steps to the right. The marker will be on 5.
b) To show 4 less than 5 Since we want to subtract, we will move to the left side. In the given example, we wish to subtract 4 from 5. So, place the marker on 5 and move 4 steps to the left. The marker will be on 1. c) To show 3 more than -5 Since we want to add, we will move to the right side. In the given example, we wish to add 3 to -5. So, place the marker on -5 and move 3 steps to the right. The marker will be on -2.

Observation
![Page 18: integers maths ppt](https://reader035.fdocuments.in/reader035/viewer/2022081417/55808bdbd8b42a08768b4680/html5/thumbnails/18.jpg)
If we want to add integers, we
will move to right side on
number line and if we want to
subtract integers, we will move
to the left side on number line.

Through this activity, students
will learn to add or subtract the
integers on number line.
