III.Procedure
A. Daily Activities
1. Prayer
2. Greetings
3. Classroom Management
4. Checking Attendance
B. Review
Teacher will ask students for the previous topic that was discussed.
C. Motivation
Part I. Games [PictuART]
Materials: slide presentation and strip paper
Aims of PictuART games
1. To enhance creativity and thinking skills of students
2. PictuART shows the abstract application of Integer in real world.
3. At the end of discussion, students will appreciate Integers in real application base on
the games they play and the video presentation.
How to play the game?
1. Teacher will group the class into two. Each group must have 3 presenters
(actor/actresses)
2. Presenters will action the word given by the teacher regarding with the picture on the
slide presentation.
3. Each group must guess the word with the help of slide presentation and their
presenters. Group will have one minute guessing.
4. The winner will gain smiley chips with 10 pts in their recitation.
Thermometer Speed Weight Zero Sign

3. Part 2. Group Activity
Materials: Flash Cards
Aims of group Activity
1. To develop active participation of students in the class
2. To gain the students of advance knowledge in the topic base on the given task.
3. To build up self confidence, creative and critical thinking among students.
4. Student themselves will discover the abstract topic through the activity and can able to
discuss it in front of the class.
Activity task
1. The teacher will divide the class into four groups and will give those flash cards
containing letters with problem operations. Each group has a task cards about the rules on
operations of integer for them to answer the flash cards problem.
2. Each group must solve the problem on the flash cards and arrange/ form a word from the
lowest to highest number of their answers.
3. The first group that finished the activity will shout a yell within their group.
4. After posting flash cards on the board, teacher will choose students in the group to
discuss their activity work provided with his/her guide questions.
D. Discussion
Students will present their activity regarding their activity work.
Teacher Guide Question:
1. What have you notice in your activity?
Our topic for today is all about operations of integer.
2. How you derive with your answer?
We follow the rules in solving problem operations.
What is our topic for today? Rules in operations of Integer.
3. How will you define integer?(added information by showing picture slide on the
presentation)
(Every recitation of students have chips and complement from the class through clap for
them to be active in class)
Integer
Are positive and negative whole number
Integers are the set of whole numbers and their opposites.
4. Teacher will post the four operation of Integer on the board.
Each operation has set of rules that needed to state by the student themselves.
Addition/ Subtraction (same rules)
Rule 1: Same sign Add = Sign of number
Rule 2: Unlike sign Subtract = Sign of biggest number
Multiplication/Division (same rules)
Rule 1: Same sign = Positive sign
Rule 2: unlike sign = Negative sign

4. 5. Teacher will show examples of operations of Integer in Addition and Subtraction.
Addition/ Subtraction Rules
Rule 1: A. 7+ 3 = 10 B. -3 - 4 = -7 Rule 2: A.7+ (-3) = 4 B. -25+ 5= -20
6. Teacher will ask students for how answers derived in the given example; what do you
think the rules used in every operations of integers?
7. Teacher will ask students if they understand the rules and will give other examples to be
answer by the students.
E. Valuing( Connecting Integer to Real life Application)
Teacher will show a video clip prior to the previous games they played and its relation to
Integer.
Title of Video Clip: (Integer in Real Application)
Guide Question (Reflection)
How important Integers in our life?
IV. Evaluation
1. -2 + 4 =
2. 7 + (-8) =
3. -6 / (-3) =
4. -23 + 31 =
5. -7 + 0 =
6. 15 – 4 =
7. -1 – 8 =
8. 8 (-2) =
9. -6 – (-11) =
10. 4 – 7 =
11. -6/(-9)=
12. -5(5)=
13. 4(-5)=
14. -5/-10 =
15. 50/10 =
V. Assignment
Bring graphing paper, ruler and pencil
Multiplication/ Division
Rule 1: A. (-2) (-3) = 6 B.12 / 4 = 3 Rule 2: A. (-22) (2) = -44 B. 12/-4 = -3
(2) (3) = 6 -12/-4 = 3
