I-OBJECTIVES
At the end of a 60-minute discussion, the first year students (Sampaguita)
are expected to do the following task with at least 75% proficiency level:
A. Identify the quadrant in the Cartesian coordinate system
B. Describe the four quadrants; and
C. Sequencing a Cartesian coordinate Plane.
II-SUBJECT MATTER
Topic: The Cartesian coordinate Plane
Reference: Elementary Algebra 1
Author: Julieta G. Bernabe
Materials: Marker, Cartolina, Graphing paper, Scotch tape
III-PROCEDURE
A. Preparation
Teacher’s Activity
Everybody stand up.
Joy. Will you lead the Prayer
Student’s Activity
Yes Ma’am
Oh! God Almighty and Loving heavenly
Father thank you for this day, thank you for
keeping as safe in coming here. Please guide us
and forgive us of all our sins and cleanse us
through the blood of our lord Jesus Christ.
In Jesus name we pray. Amen!
Good morning class!
Before you sit will you please?
arranged your chair.
Good morning Ma’am
(Students do they said Instruction)
Class sit down.
Who among your classmates are
absent today?
None Ma’am
Good!
B. Review
Are you ready to listen?
Class, do you still remember our lesson
yesterday?
What is our lesson yesterday?
Judith.
Yes Ma’am
Yes Ma’am
Ma’am
Our lesson yesterday is about
solving first degree inequalities in one variable.
Very good!
Who can give an example?
Yes Cajilig.
Ma’am
X>6 & X<-1
Good!
C. Motivation
Before we start our lesson this
morning, I have here some pictures that I will
show to you. All you have to do is to observe
and say what pictures is it.
Before that I will group you into two
groups, then each group should have one
representative to give the correct answer.
Understand class?
Yes Ma’am
D. Presentation
Class, based on the activity you did,
do you have an idea if what is our lesson
this morning?
Anyone from the class, Mark.
Yes Ma’am
Our lesson for today is about the
Cartesian coordinate Plane.
Very good!
E. Lesson Proper
Our lesson for today is all about The
Cartesian Coordinate Plane.
First, What is Cartesian Coordinate
Plane?
Yes Isabel.
Ma’am
The Cartesian coordinate plane is a
rectangular system picturing a relation where
each part corresponds to exactly one ordered
pair of real number.
Very good!
So, the Cartesian Coordinate plane is a
rectangular system picturing a relation where
each part corresponds to exactly one ordered
pair of real number.
What are the four quadrants in Cartesian
Coordinate Plane?
Yes Adonis.
Ma’am
The four quadrants of Cartesian
Coordinate plane are: QI, QII,QIII, and QIV.
Very good!
Who can show the different quadrant on
the board? Yes Mantal.
What do you called the number
lines intersect the point denoted by
the O?
(Mantal do they said instruction)
Ma’am
It is called Origin.
Yes Bonales.
Good! The intersection point, denoted as
O at (0, 0) of two perpendicular Number lines
at their zero point is called Origin.
What is the horizontal number line which
helps to form the coordinate plane?
Yes Morante.
Ma’am
X-axis
Very good!!!
How about the Vertical number line?
Ma’am
Y-axis
Valencia.
Very good!!!
So, in Cartesian Coordinate Plane. We
notice that the axis divide the plane into four
quadrants labeled with Roman numeral I
through IV in a counter-clockwise direction.
Each point in the plane in names as an
ordered pair (x, y). The first number X is
called X-coordinate or abscissa and the second
number Y is called Y-ordinate.
What is the sign of an ordered pairs in IQuadrant?
Ma’am
Talingting.
The I-Quadrant is composed of (+, +)
positive or both positive
Good!
How about the Quadrant II?
Jud.
Ma’am
Quadrant II is composed of (-, +)
negative and positive
Very good!
How about the Quadrant III?
Labrador.
Ma’am
The third Quadrant is composed of (-, -)
or both negative
Very good!
And the last what is Quadrant IV?
Sotto.
Ma’am
The Quadrant IV is composed of (+, -)
positive and negative
Very good!
F. Application
Class, did you understand our lesson?
Again, What are the four Quadrants in
Cartesian Coordinate Plane? Ocampo.
Very good!
G. Generaliz ation
Now, lets have an activity. I will group
you into four groups each group should have
one representative to present your work. (I
give you 5 minutes to do this activity).
Directions:
Draw a Cartesian Coordinate Plane
and label the four Quadrants.
Yes Ma’am
The four Quadrants are; Q-I, Q-II, Q-III, Q-IV.
