PROCEDURE
Teacher’s Activity
A. ACTIVITY
1. Preliminary Activities
a. Prayer
Before we start, everybody stand
up for a prayer. The in-charge for
today’s prayer, please lead the
class.
Student’s Activity
b. Greetings
Good morning, class.
Good morning sir
c. Checking of Attendance
Class monitor, kindly check the attendance
2. Review
What was our topic last meeting?
Last meeting our topic is all about angles
formed when two lines cut by a
transversal.
Now, what are the different angles
formed when two lines cut by a
transversal?
Very good! Now what do you call an
angles formed that lie between two
lines?
The different angles formed when two
lines are cut by a transversal are Interior
angle, Exterior angle, Alternate Interior
angle, Alternate Exterior angle and
corresponding angle
They are called Interior Angle
--∞ continue until all angles formed will
identify--Very good! Now any questions?
No sir
If none we will proceed to our new
topic, but before that we will have an
activity first.
3. Motivation
I have here a figure that will help you
formulate the definition of a polygon.
I will paste on the board.
Class take a look at figure on the
The student study the figure
board and study about it.
The following are not polygons.
The followings are polygons
What have you notice in the two
groups of figure?
The first group represent figures which
are not a polygons and the 2nd one are
polygons.
Very good! Now what do you think
our topic this morning?
It is all about polygons.
Very good!!
4. Statement of Aim
This morning our lesson is all about
different kinds of polygons. At the
end of the lesson you are expected
to: (a) Define Polygons; (b) Identify
the different kinds of Polygon
according to the number of sides and
number of angles; (c) Actively
participate in the class discussion
with 95% mastery level.
B. ANALYSIS
1. Discussion
What have you notice in the given
groups of polygons?
They are close figure
Very good! What else? What have
you notice on their side?
Their side is made up of line segments
joined at their endpoints.
And as have you notice, how many
minimum number of line segment
does a polygons have?
There are three or more line segments.
Very good! Now based on what you
have discovered how would you
Polygons are close figure made up of
three or more line segments joined at
define polygons?
their endpoint.
Very good! Do you know that
polygons are named according to the
number of its sides and angles?
Okay! Let’s take a look to this figure.
Can we consider this a polygon?
Why you say so?
Yes sir
Because it is a close figure made up of
three line segment joined at their
endpoint.
Very good! What do you think the
shape is this?
Triangle
Can anyone tell me what make a
triangle different from other shape?
A triangle has three sides and has three
angles
Very good! In addition we call this as
triangle from the prefix “tri means
3”. It is clear??
Yes sir
Let’s proceed with the next figure.
Can we consider this figure as
polygon is this?
Yes, sir.
Very good.
What polygon do you think is this?
Quadrilateral
It has four sides and four angles.
What can you say about it?
Very good.
Also, we can name this polygon as
quadrilateral because of its prefix
“quad” means four.
Yes, sir.
Understand?
Now, let’s proceed to the next figure.
Can we consider this as a polygon?
Yes, sir.
Now, what polygon is this?
It is called pentagon
What can you tell me about it?
It has five sides and five angles.
Very good!
We call this polygon as pentagon
because of its prefix “pent” means 5.
Again what does “pent” means?
Pent means 5.
Very good, any questions?
No, sir.
Continue for hexagon, heptagon,
octagon, nonagon and decagon.
(Students should be able to identify
the number of sides and possible
angles for each polygon).
(the students will continue up to the last
number of sides and angles of each
polygon)
Excellent, class!
I know that you’ll find it easy to name
and identify the different types of
polygons.
Now in addition, always remember
that a polygons that having equal
angle is called regular polygon, and
to those who have not is called
Irregular polygons.
Is it clear?
C. ABSTRACTION
Based from our discussion, what is a
polygon?
Yes, ____?
Yes, sir.
A polygon is a close plane figure made up
of three or more line segment joined at
their endpoints.
Very good!
Now, what were the different types of
polygon that we already discuss?
The different types of polygons are
triangle, quadrilateral, pentagon,
hexagon, heptagon, octagon, nonagon
and decagon.
Very good.
Now, what type of polygon that having 3
sides and 3 angles.
It is a triangle.
Very good.
How can you say that a triangle has sides
and 3 angles?
From the prefix “tri” means 3.
Very good.
(continue until all types of polygon were
identify)
Very good.
Do you have any questions?
D. APPLICATION
I will give each row a ruler, and answer
sheet, then draw the following regular
polygon inside each box.
No, sir.
1. A regular polygon with 3 sides.
1.
2. A regular polygon with 4 sides.
2.
3. A regular polygon with 6 sides.
3.
4. A regular polygon with 10 sides.
4.
I will give each row 3 minutes to do
the activity and afterwards we will
check your papers.
The group that will get a perfect
square will also gain a perfect
participation in this session.
“Accuracy is a must”
Are you ready?
Yes, sir.
You may now start.
God bless.
