REVIEW (3 minutes)
Strategy: ICT Integration (E-GAMES)
Directions: Describe the following polygon by counting the number of
sides of each polygon.
MOTIVATION (5 minutes)
Strategy: Game (Bring Me)
Direction: The students will bring the objects that the teacher will ask from
them. They are given 1 minute to find the particular object, the first student
who can bring each object will receive a prize. Remind each pupil to be a
good sport when playing games.
Objects to bring:






B. Establishing a purpose for the lesson
Coins
Circular bracelets
Circular plate
Cover of Circular food container or any container
Water bottle cap
Circular ponytail
(2 minutes)
From the activity that we have done what do you think is our lesson for
today? Anyone?
A lot of objects around us are circular in shape such as coins, plates,
and wheels. This lesson is essential for you to understand the terms related
to a circle. These terms are easy to remember and very useful in our daily
life.
After going through this lesson, you are expected to:
 Identify the terms related to a circle.
C. Presenting examples/Instances of the new
lesson
a. Strategy: Paper Folding Activity (4 minutes)
Mechanics:
1) Divide the class into 4 groups.
2) Give each group a piece of circular cutout.
3) Let them fold it in half. (Focus the pupils’ attention on the line segment
formed by the fold. Introduce the term Diameter to name the line segment.
4) After that, let them fold the cutout such that the diameter is halved.
(Introduce the term radius to the name of the new line segment formed).
How the length of the radius compares with the diameter? What is a
diameter? What is a radius?
5) Using a marker, let them mark the center of the circle. (Specify that a
center named the circle.
b. Strategy: Lecture Method (10 minutes)
Terms Related to a Circle
D. Discussing new concepts and practicing
new skills
Strategy: Collaborative Learning (10 minutes)
Directions: Group the class into four. Use the illustrated circle at the right
in answering the items in the activity.
Group 1- “Name Me”
Directions: Name the following parts of circle P.
1) 3 radii
2) diameter
3) 3 chords
4) 2 central angles
5) tangent line
6) secant line
7) inscribed angle
Group 2- “Identify Me”
Directions: Identify the following parts of Circle O.
Group 3- “Match – Up”
Directions: Refer to the figure shown. Match the parts of Circle O in
Column A with the name of each part in Column B.
E. Developing mastery
(4 minutes)
Directions: Use circle O at the right to identify each line segment as a
radius, a diameter and a chord.
1. Line AC
2. Line OA
3. Line FM
4. Line OD
5. Line OC
6. Line OF
7. Line AB
8. Line DC
F. Finding practical application of concepts
and skills in daily living
Before we will proceed to our next activity, can you sight any experience
of yours on how circles are used in our daily lives?
Strategy: Think-Pair-Share (3 minutes)
Problem
An electronic and communication engineer designed a circular disk
to be put up in a call center building. Before he installs the disk, he let his
men check the disk and its parts. Supposed, I am the engineer and you are
my working men, what are now the parts of the circular disk? Identify the
radius, chord, diameter, secant and tangent given the figure.
You will be only given 3 minutes to do the task.
G. Making generalizations and abstractions
about the lesson
Your time starts now.
(2 minutes)
So, now who will give the recap of the things that we have discussed
today?
H. Evaluating learning
(5 minutes)
Directions: Choose the correct answer from the words inside the box
_________1) It is the set of all points in a plane with the same distance
from a certain point.
_________2) It is a line segment joining two points on the circle.
_________3) It is a chord that connects two points on the circle and passes
through the center of the circle.
_________4) It is a line segment from the center of the circle to any point
on the circle.
_________5) It is an angle formed by two radii.
