MOTIVATION
What’s your target score in a 20-item test? What passing grade is it? (75%, 80%, 90%, or
100%? The pupils have the freedom to choose.
Ask: Do you need to study your lesson every day? Do you listen well and participate in class
discussion?
Ask: Why do you need to study? Will it help you prepare for your future? Emphasize the value of
being studious and participative.
1. Presentation:
Allan, a boy from a fishing village is a diligent and studious pupil. He goes to school ever day
and does his work well. He never skip studying his lesson every night. When he took their 50-item
quarter examination he got 96% of it correctly? What is his score?
Ask:
*Who is the boy from the fishing village?
*How is he as a pupil?
*Did he do well in school? How do you know?
*What rating does Allan get in the test? Is this a high rating? How do you know?
*Will you do thee same? Why?
2. Performing Activity
Ask the pupil to work in 4 groups in solving the problem.
Use the formula: P=R x B
P = 96% x 50
P = 0.96 xx 50
Change 96% to decimal = 0.96
P = 48
Allan got a score of 48
3.Analysis
* How do we solve for the percentage?
* Did you move the decimal point of the rate from right to left?
* How many move of decimal point do we move?
4.Abstraction
Explain how to find the percentage. Use this problem.
Gonzales’ Family Weekly Budget of P2 000..00
Food
65% of P 2 000 =
P1 300
School Supplies
7% of P2 000 =
P 140
Fare
8% of P 2 000 =
P 160
Savings
20% of P 2 000 =
P 400
Use the formula: P = R x B
Find the percentage of each by changing percent to decimal.
1. 12% of 40 = ___________
3. 11% of 90 = _____________
2. 75% of 300 = ___________
4. 36% of 150 = _____________
5. Summarizing the Lesson
Elicit from the pupils the ways of finding the percent of thee given number. Guide them to
generalize that finding thee percent of a whole is also finding part of the whole.
To find the percentage use the formula: Percentage = Rate x Base (P = R x B)
