4. REVIEW
Class let’s have a simple game entitled
“THE MYSTERY ENVELOP” I will call two
students to pick an envelop on my hand.
After picking, I will let the student to call someone
on the group to answer a question on the mystery
envelop. The holder of the envelop and
the one who answer the question correctly will
have a price. But when they provided the wrong
answer they will not get any prize.
Now, let us begin.
Jovelyn please pick an envelop on my
hand.
( the student will pick an envelop on my hand)
(the student will call someone to answer the
question)
Please call someone who will answer the
question on the mystery envelop.
Jovelyn, please open the envelop and
read the question. What is the formula in finding the volume of a
cube?
( the second student will answer)
The formula in finding the volume of a cube is
V=s3
Very good, the formula in finding the
volume of V=s3 Here is your price
Please pick another envelop, Raymond.
(Raymond will pick the last envelop)
Please call someone who will answer the
question on the mystery envelop.
(Raymond will call someone to answer the
question)
Raymond, please open the envelop and
read the question. What is the formula in finding volume of a
rectangle?
( the second student will answer)
lOMoARcPSD|15368832
The formula in finding the volume of rectangle is
V=L*W*H
Is he correct class?
Yes, sir!
Excellent! The formula in finding the volume of
rectangle is V=L*W*H. Here is your price
(the teacher will give a prize)
Last meeting, we have discuss about volume, and
volume is about the amount of 3-dimensional
space occupied by an object.
5. MOTIVATION.
Before we start our lesson. I will ask
3 different questions, each question is worth a
prize.
Let’s begin.
Travis, what is the shape of a coin? Circle, sir!
Very good!
Raven, what is the shape of wheel? Round or circle, sir!
Excellent!
Now, class what is the shape of a pie? Circle!
B. Lesson Proper
PIE GRAPH
Class, kindly read.
Pie Graph
2. DISCUSSION
Pie Graph are used to show the percent
of a quantity in each of the several
categories. It can also be used to easily
visualized a ratio.
April, what is a pie graph. Pie Graph are used to show the percent of a
quantity in each of the several categories. It can
also be used to easily visualized a ratio.
Very Good!
Pie graphs are also called Circle graphs
because they are shaped as a circle. The entire
circle is considered as a whole.
Let’s have an example.
lOMoARcPSD|15368832
There are 24 hours in a day and you
spend 8 hours at school, 8 hours in
sleeping, 2 hours studying, 2 hours
playing and 4 hours watching TV.
Let’s create a Pie Graph using the given
data. First let us draw a circle.
After creating a circle.
Let us analyze the data and compute for the
percentage:
• There are 24 hours in a day.
• 8 hours in school • 8 hours in school
= 8/24*100 =33.33 or 34% = 8/24*100 =33.33 or 34%
• 8 hours in sleeping. • 8 hours in sleeping.
=8/24*100=33.33 or 33% =8/24*100=33.33 or 34%
• 2 hours of studying. • 2 hours of studying.
=2/24*100=8.33 or 8% =2/24*100=8.33 or 8%
• 2 hours of playing. • 2 hours of playing.
=2/24*100=8.33 or 8% =2/24*100=8.33 or 8%
• 4 hours watching TV. • 4 hours watching TV.
=4/24*100=16.67 or 17% =4/24*100=16.67 or 17%
After computing for the percentage, let us
divide and construct the pie graph.
lOMoARcPSD|15368832
Do not forget to label your Pie Graph.
Yes, sir!
Did you get it class?
Let’s try a harder one, open your notebook
and try this one.
Tittle: Students Grade
Here is how many students got each
grade in the recent test:
A B C D
4 12 10 2
Create a Pie Graph using the data. I will
give you 5 minutes to compute for the percentage
and create a Pie Graph.
( students will answer the question)
Total number of the students= 28
A. = 4/28*100=14%
B. =12/28*100=43%
C. =10/28*100=36%
D. =2/28*100=7%
Pie Graph
Yes, sir!
( after 5 minutes)
Are you done class?
Let’s solve the problem and check your paper.
Exchange note book with your seatmates.
lOMoARcPSD|15368832
Total number of the students= 28
A. = 4/28*100=14%
B. =12/28*100=43%
C. =10/28*100=36%
D. =2/28*100=7%
Pie Graph
Do
you have the same Pie Graph class?
Yes, sir!
Excellent!
What is the total number of students, Vavit?
There are 28 students, sir!
Very good!
There are 28 students.
Maja, what is the percentage of the students
who got an A grade.
The percentage of the students who got an A
grade is 14%.
Very Good!
14% of the student got an A grade.
Rico, what is the percentage of the students
who got a B. grade?
The percentage of the students who got a B
grade is 36%.
Very Good!
lOMoARcPSD|15368832
43% of the student got a B grade.
Jobelle, what is the percentage of the
students who got a C grade?
The percentage of the students who got a |C
grade is 43%.
Very Good!
43% of the student got an A grade.
And last, what is the percentage of the students
who got a D grade?
The percentage of the students who got a |D
grade is 7%.
Excellent!
7% of the student got a B grade and a total
100%.
3. APPLICATION
To test your ability. I will divide you in two
groups. Please count from 1-2. ( the students will count from 1-2)
All students whose number is 1, please stay
from the Left side and those whose number is 2
will stay on the right side. ( the will go to their assigned group)
Please assign a group leader. ( the student will assign a group leader)
I will give you materials for this
activity. You will answer this problem:
1. The table below shows the data on Grade 6
pupil’s favorite vegetable.

(after 10 minutes)
Are you done class?
Yes, sir!
Please present your work on the class. Let us
start from Group 1. ( group 1 will present their work)
Thank you so much. Let’s give them a bib big
hand.
Now, Group 2 please present your work.
( group 2 will present their work)
Thank you so much. Let’s give them a big
hand.
4. VALUING
Nice, what is the value of using Pie Graph in
our daily life?
The value of using Pie Graph in our daily life is
that it make our life easier by presenting every
huge data into pieces and it can display data in a
lOMoARcPSD|15368832
simpler way.
Excellent!
Pie graph is valuable in our life. Imagine if we
cannot express data in Pie Graph. We cannot
understand the data in a simpler way. Thus, Pie
chart is very useful in business data, schools and
places and work all over the world.
5. GENERALIZATION
Class what have we discussed today?
Pie Graph
Raven, what is Pie Graph?
Pie Graph are used to show the percent of a
quantity in each of the several categories. It can
also be used to easily visualized a ratio.
Very good!
Pie graph are also called Circle Graph
because they are shape as a circle and the entire
circle is considered as the whole.
IV. Evaluation
I have prepared an individual activity
to test whether you understand our
discussion.
1. According to the National Statistics
Office, the number of Overseas Filipino Workers
(OFWs) who worked abroad at any time during
the period of April to September 2018 was
estimated at 2.3 million.
Given that:
• Australia = 10%
• North and South America=25%
• Africa=5%
• Asia=50%
• Europe=10%
A. Construct a Pie Graph using the data.
B. How many OFWs are working in Europe
and Asia.
I will give you 10 minutes to answer the
problem. Your time start now.
A. Construct a Pie Graph
lOMoARcPSD|15368832
B. How many OFWs are working in Europe
and Asia.
Europe=10%
Asia =50%
Europe:
10%*2.3 million= 230,000
Asia:
50%*2.3 million = 1,150,000
230,000 + 1, 150, 000 = 1,380,000
(after 10 minutes)
Are you done class? Yes, sir!
Now you may pass your activity sheets.
V. Assignment.
For your assignment, I want you to collect
your grades in Mathematics in 1st Quarter to 3rd
Quarter and create a Pie Graph.
Write it on your assignment
notebook. Do you understand class?
Yes, sir!
Let’s call it a day, Goodbye class!
Goodbye, Sir!
