The students will pick one mathematical expression to evaluate. If

answered correctly, the tile will disappear and the picture will be
revealed slowly.
C. Motivation The Tale of Addition
Long, long ago, and very far away, two villages existed. In the first village
lived the POSITIVES. They were integers who worked hard and cooperated
to get along well. They liked themselves very much!
On the other side of the forest lived the NEGATIVES. Like the positives,
the negatives also worked hard, cooperated with each other and liked
themselves very much.
Every morning, integers from each village would enter the forest to hunt.
Sometimes, the positives would meet up with other positives, then they
would happily join forces for the hunt.
Likewise, sometimes, the negatives would meet up with other negatives.

Then, they too, would happily join forces for their hunt.
That is, positives and positives join forces. In the same way, negatives and
negatives join forces. This has always been and always would be the way of
things. Everything was always beautiful and peaceful within the integer
villages. Peaceful that is until the positives and negatives crossed paths.
Then – things would quickly take a deadly turn!
Whenever a positive met up with a negative, it was an ugly and very bloody
battle. It was a battle to the death in which each combatant would ultimately
and tragically give his life.
You see, during the battle, each pair of combatants would “cancel” each
other. For example (+7) + (-2) = +5
Since there are 5 more positives than negatives, the positives would claim
victory with 5 survivors.
Yes, a tragic story indeed. Yet, it is through their tale of happiness and
sorrow that you have been given the knowledge of integer addition. Never
forget: The integers will either fight or join forces. Now you know the truth!
And so it is that we conclude the bittersweet tale of the story of the Integers.
The End.
D. Presentation of the Lesson
1. Activity Activity
One student will be called to model each situation on the board using
the algebra tiles.
1. Combine 5 positive signed tiles and 3 negative signed tiles.

Count how many signed tiles you have.
2. Combine 2 negative signed tiles and 5 negative signed tiles.

3. Combine 15 positive signed tiles and 20 negative signed tiles.

2. Analysis
Hence, 5+ (−3 )=2
Hence, (−2 ) + (−5 )=−7
Hence, 15+ (−20 )=−5

3. Abstraction Ask the following questions:
1. Based on the activity and diagrams how are we combining the signed
tiles?
2. How will you identify the sum?
3. On your own words how will you add integers with same sign and
different signs?
ADDITION OF INTEGERS USING THE RULES:
Rule 1: When the integers have like signs, add the numbers and copy the
common sign.
Rule 2: When the integers have unlike signs, subtract the numbers and use
the sign of the number with the greater absolute value.
4. Application Solve the following word problems:
1. Zack just got a grade of 93 on a report. However, because he

turned it in late, his teacher is going to deduct 15 points. What will
Zack’s final grade on the report be?
2. The temperature rose from 0°C by 8°C but later dropped by 10°C.
What is the resulting temperature?
Recitation
E. Generalization To sum it up, let us complete the statements. Choose your
answer from the box that best completes each of the
statements below.
1. When the signs are the same, ________ and keep the sign.
2. When the signs are _________________, subtract and use
the sign of the number with the greater absolute value.
3. If we add two same numbers with different signs, then the
answer is equal to __________________.
4. The sum of two negative integers is a ___________ integer.
5. The sum of two positive integers is a ____________ integer.
IV. Evaluation Solve the following problems:

1. What is 10 more than -2?
2. Angela deposited P800 in the bank in the first day of the
month and P600 the following day. How much money
does Angela have?
3. Carrot Man gained P10 on the first day, lost P5 on the
second day and gained P20 on the third day. How much
profit does Carrot Man have during his three days of
selling?
Find the sum of the following:

1. -48 + 17
2. -84 + 79
3. 63 + (-49)
4. -88 + (-33)
5. 8 + (-17) + 24
V. Assignment Follow the arrows as you fill in the correct math solutions! Can you get to
the end with no mistakes?
VI. REMARKS
VII. REFLECTION
A. No. of students who earned
80% in the formative
assessment
B. No. of students who require
additional activities for
remediation
C. Did the remedial lessons
work? No. of learners who
had caught up with the
lesson
D. No. of learners who continue
to require remediation
E. Which of my teaching
strategies work well? Why
did these work?
F. What difficulties did I
encounter which my
principal or supervisor can
help me solve?
G. What innovation or localized
materials did I use/discover
which I wish to share with
other teachers?
