Classroom Management
If you have something to say, state Yes, Teacher!
your name and I will allow you to open
your mic to speak or just type it on the
chat box provided. Jot down notes so
you will immediately understand this
lesson. Is everything clear?
B. Priming Activity
Recall/Remembering
Did you remember our lesson that we Our lesson last time was all about visualizing
discussed last time? percent and its relationship to fractions,
ratios, and decimal numbers using models.
What is percent? It is a rating in which a number is compared
to one hundred (100).
How do you visualize percent? Through model representation, it can be
written as ratio, decimal, or a fraction that
used to indicate that a number is divided by
one hundred (100).
Review
To test your memory again,
categorize this model in a form of
ratio, fraction, decimal
66:100, 66/100, 0.66
43:100, 43/100, 0.43
28:100, 28/100, 0.28
C. Development of the Lesson
a. Activity
Motivation
Before we start to our lesson proper, do you Yes, Teacher!
know the game entitled “Wheel of Fortune”? Yes, we are!
To begin with, the teacher will put 3 letters in
random place and also spin the roulette
wheel, when your name points to the arrow,
he/she will choose a letter from the alphabet
that consists of blank spaces they must fill in.
After random selection to see who begins,
either teacher take turns to spin the wheel or
the next student he/she called guess a
consonant. If you see the hint to solve the
puzzle and you got the correct answer, you
are a winner. Are we clear to the game

b. Analysis
1.) In a certain school, 72% of the boys are
playing football. There are 150 boys in
that school. How many boys are playing
football?
Let’s study the problem:
In the given problem, what is the;
Base 150
Rate 72%
Percentage It is asked
What fundamental operation we will Multiplication
used?
So, the formula of percentage will be
P=BxR
whereas;
P is percentage, B is base, and R is rate.
But before that, you have to express the
rate as decimal before multiplying.
72% = 0.72 Yes Teacher!
Did you get it?
It is written as 150 x 0.72 = N
How do we write it in a number sentence? 150 x 0.72 = 108
What will be the answer?
Therefore, 108 out of 150 boys are
playing football.
Every percent problem has 3 elements:
Percentage – is the part of the base
whose value is determined by the rate
and it is usually before the word ‘is’.
Base – is the total amount or value of
the whole which a part is taken and it
is after the word ‘of’.
Rate – is the comparison of the
percentage to the based expressed in
percent (%) sign.
Here are other examples in identify
percentage, base and rate. Please
answer it. Given Base Rate Percentage
Given Base Rate Percentage 25% of 24 is 6 24 25% 6
25% of 24 is 6 10% of 80 is 8 80 10% 8
10% of 80 is 8 90% of 50 is 50 90% 45
90% of 50 is 45
45
2.) A basketball team won 75% of the game
played. If the team played 24 games, how
many games did they lose?
First Method: Solution by Proportion
75_ = N part
100 24 whole
100 N = 75 X 24
100 100
N = 75 X 24
100
N = 1800
100
N = 18 Yes, we did!
Did you understand the first method?
Second Method: Solution by Multiplication
P=BxR
But, express first the percent into decimal
form.
We place the pen after number five and move
How do we express 75% in decimal? two decimal places to the left then put it
before number seven
75% = 0. 75
= 24 x 0. 75%
= 18 Yes, we did!
Did you understand the second method?
Therefore, the team loses 18 games
To find the percentage in a given problem
quickly, remember the following:
Rate - is the number followed by the word
percent (%).
Base - is the number that followed the words
percent of (% of).
Percentage – is the number left after rate and
base have been identified. Yes, we are!
Are we clear on how to find percentage?
Yes, we are!
Are you familiar with this? It is a Techan’s Triangle
What is this?
It is an easy way to solve for unknown
number quickly. The formulas are as follows:
P=BxR
B=P/R
R = P / B x 100 Yes, we did!

3.) Manuel is a diligent and studious pupil
goes to school every day and does his
work well. He never skips studying his
lesson every night, when he took their 50-
item quarter test, he got 96% of it
correctly. What is his score?
In this problem, we will use Polya’s four-
step process for problem solving which is
used all over to aid people in problem
solving. No, we aren’t
Are you familiar with this process?
Here are the steps:
Steps Answer
1. Understand the problem.

correctly.
Did you understand our lesson for this day?
c. Abstraction
Can you identify base, percentage Percentage – is the part of the base whose
and rate in a problem? value is determined by the rate and it is
usually before the word ‘is’.
Base – is the total amount or value of the
whole which a part is taken and it is after the
word ‘of’.
Rate – is the comparison of the percentage to
the based expressed in percent (%) sign.
Do you know how to find the To get the percentage (P) of a number,
percentage in a given problem? multiply the base by the rate. Express the
rate as a decimal before multiplying.
Do you know how to analyze and To solve word problems involving percents,
solve problems involving identify first what is the unknown number.
percents? The three types of percent problems involve
finding the percentage, base and rate.
For Percentage, P = B x R
What are the formulas to find the For Base, B = P / R and;
unknown number? For Rate, R = P / B x 100
d. Application
Now, let’s have a quiz bee about
the lesson that we have discussed
earlier. May I ask all of you to
prepare your own pen and paper.
Yes, Teacher!
Direction: Teacher prepared a set
of questions to be answered by
learners in a show-me-board
within 10 seconds. Be sure to your
answer because your answer you
raise will be your final answer, in
short, no return and no exchange.
Is the instruction clear to all of
you?
IV. Assessment/Evaluation
This time, the teacher will send a link Yes, we are
of your quiz that able to answer within
5 minutes. There is an instruction on
how to answer. If you have questions
and clarifications, just turn on your
mic then ask your teacher regarding
the quiz. Class, are we clear to this
matter?
