Student’s Activities
Let us all stand up and feel the presence of the Lord. Ms. Arias please lead
the prayer.
Amen!
Before seating down please arrange your chairs quietly and pick up the
papers and candy wrappers under your chairs.
let’s have first a math trick.
Do you want a math trick?? Are you ready? So get any piece of paper
and ball pen.
Yes, sir!
Write your month number from your birthday. For example, if your
birthday is June then your month number is 6.
Then, multiply by 5. Next, add 6.
Multiply the total by 4. Add 9.
Multiply by 5 once again. Then, add your birth date.
If you were born on the 14th, then add 14. And last, subtract 165.
You will surprise because you will have the month and day you were
born.
Done sir!
Are you done on computing?
What have you notice in the trick? Exactly.
In order to get the right answer, you
need to follow the rules and
instructions!
I hope it energized you all.
B. Establishing purpose for the lesson
Last meeting, we have discussed about integers.
Integers are a set of positive and negative
number.
So what do you mean by integer?
Yes Ms. ___________ Very good.
18
How will you define the absolute value of a number?
The absolute value of a number is its
distance from zero to the number line.
Excellent! Now let us study the image below.
It is a line graph Sir!
What can you say about it?
Very good! And it also contains what?
Yes, that’s right!
It contains numbers with negative and
positive signs!
At the center!
Where is the location of the zero number?
How about the positive numbers?
At the right side of Zero!
At the left side of zero!
What about the negative numbers?
Today we are going to use this number line to show the addition of two
integers starts with 0. Move to the right to add positive integers and move to
the left to add negative integers!
At the end of the 60 minute you should be able to:
1. To perform addition on integers
2. Memorize the rules in addition of integers
3. Solve problems involving integers
Are you ready class?
19
Yes, Sir!
C. Presenting examples/instances of the
new lessons
Using the line graph that shows the addition of two integers let us analyze
these following questions.
1. From 0, take 4 units to the right and another 3 units to the right what
was the resulting number? How far is it from the zero?
2. From 0, take 6 units to the left and another 4 units to the left what
was the resulting number? How far is it from the zero?
1. The resulting number is 7. It is 7
units away from the zero!
2. The resulting number is negative
10. It is 10 units away from zero.
Yes, very good!
D. Discussing new concept and
practicing new skills #1
Let me divide you into 3 groups. Row 1 will be group 1. Row 2 will be
group 2 and row 3 will be group 3. Each group will be given 5 minutes
and another 2 minutes for presentation of your activity.
Activity 1: Hop on me!
Using the line graph illustrated a while ago, give the resulting
numbers if we takea.

5 units to the right of 3?
4 units to the right of 8
2 units to the eft of -5?
3 units to the left of -6?
5 units to the left of 2?
5 units to the right of -3?

Remember that we have house rules to follow:
 Be respectful
 Be participative
 Be collaborative
Are there any questions? If none your five minutes starts now!
Let us give a round of applause to each and every one of you!
E. Discussing the new concept and
Let us more explore on how to add integers!

8 units
12 units
-7 units
-9 units
3 units
practicing new skills #2
Again let us use the number line to add the following integers.
a.
b.
c.
d.
4+3
7 + (-6)
-4 + (-4)
-8 + 6
Let us now analyze the rules in adding integers.
What can you observe when you are adding like signs?
When adding common signs, you need to
copy the sign.
Excellent!
LIKE SIGN: (+) + (+) or (-) + (-)
 Find the sum of their absolute values and use the sign common to
both integers
 Example: 8+8= 16 while (-8) + (-8) = -16
How about adding an unlike sign?
Very good!
UNLIKE SIGN: (+) + (-) or (-) + (+)
 Find the difference of their absolute values and use the sign of the
integer with the greater or larger absolute value.
21
When adding unlike signs you need to
subtract and copy the sign of the larger
number.
F. Leads to formative assessment
 Example (-3) + 8 = 5 while 13 + (-5) = 8
let us have a board game!
Please remain in your group and follow my instruction:
1. Each group must contain 10 members
2. The group member will go to the board one by one and pick 1
question to answer.
3. The first group who got the highest score will be the winner and get
their reward.
4. You only have 15 minutes to answer in the board!
Is there any question? If none let’s get ready!
G. Finding practical applications and
concepts and skills in daily living
None sir!
I will show you a video clip entitled Application of Integers in Real
Life.
While watching the video, you’re going to take note of what you have
noticed in the video. Is that clear?
If that so, here is the video. (The teacher will play the video) (after the
video presentation)
What can you say about the video the video? Yes Ms._______________
Thank you. Another?
The video shows us how integers are being
used in this world.
The video tells us that we don’t have to hate
mathematics because it is already part of us,
whether we like it or not, math is around us.
We can’t deny the fact that almost all of the students nowadays hate
mathematics a lot. But why?
Though mathematics is really part of our life. Everything we do is part
of math. When we are eating, taking a bath or even when we travel.
There is always an integration of mathematics.
H. Making generalizations and
What did you learn from our lesson?
22
Sir! I learned how to use number line in
adding integers both positive and negative.
abstractions about the lesson
Sir I memorized the rules in adding
integers.
Sir I learned that negative numbers are also
important in our lives!
I. Evaluating learning
DIRECTION: Get ½ sheet of paper. Read each question carefully. Choose the
letter of the correct answer and write it on the space provided before each
number.

b. -2
c. 2
d. -138
2. Which equation is true?
a. 6+7 = -13
b. (-15) + 6= -9
c. -6 + (15) = -9
d. None of the above
3. If we are going to add 52 to -7 what will be the answer?
a. 45
b. -45
c. 59
d. -59
Illustrate using the number line
