A. Reviewing previous
lesson or presenting
the new lesson
Ask the following questions:
1.) What is the linear term of y = 4x 2 + 2x – 3?
2.) What is the linear term of y = x 2 – 5x?
3. What is the constant term of y = x 2 – 5x?
4. Can the quadratic term be zero?
B. Establishing a
purpose for the
lesson)
Literacy:
Note: (Let learners arrange the given letters to form a word PARABOLA.
And let them arrange the words to form a complete sentence.)
A parabola is a U-shaped plane curve where any point is at an equal
distance from a fixed point.
C. Presenting
examples/Instances
of the new lesson
Applied knowledge of content within and across curriculum teaching areas.
Science: Describe the horizontal and vertical motions of a projectile.
(The teacher will ask about parabola/s and let students give example that
shows parabolas or parabolic path).
D. Discussing the new
concepts and
practicing new skills
nullQuadratic Functions
The graph of a quadratic function is a parabola.
A parabola can open up or downward.
If the parabola opens upward, the lowest point
is called the vertex (minimum).
If the parabola opens downward, the vertex
is the highest point (maximum).
Standard Form
The standard form of a quadratic function is y = ax 2 + bx + c.
The parabola will open up when the
a value is positive.
The parabola will open downward
when the a value is negative.
(Note: The teacher will continue to discuss the lesson).
E. Discussing new
concepts and
practicing new skills

(GROUP ACTIVITY)
Battleship
HOW TO PLAY: (ICT Integration)
Questions must be answered correctly to reveal the block selected
If you answer correctly AND hit a ship, you may gain 2 points.
If the answer is wrong, it’s the opponent’s chance to attack/answer.
F. Developing mastery
(Leads to formative
assessment 3)
Group Activity: Try This!
Group 1: Determine the vertex and axis of symmetry
Group 2: Identify the opening of the graph, minimum or maximum value
Direction: Determine the direction of opening of the parabola, the vertex, the
axis of symmetry and minimum or maximum value, of the following
quadratic functions.

G. Finding practical
application of
concepts
and skills in daily
living)
Carl Allan hit the volleyball at 3 ft above the ground with an initial velocity
of 32 ft/sec. The path of the ball is given by the function S(t) = -16t 2 + 32t +
3, where S is the height of the ball at t seconds. What is the maximum height
of the ball?
a. What kind of function is used to model the path of the volleyball?
b. What is the maximum height by the ball?
c. What is represented by the maximum point of the graph?
Real life scenario: HOTS Questions
Like graphs of quadratic function, your life is full of ups and downs. Without
the “downs” your “ups” would mean nothing.
*Have you encountered any situation that you feel so down? How did you
manage to stand and move up?
Applied knowledge of content within and across curriculum teaching areas.
ESP 7: NaipaliLiwanag na ang paglinang ng mga angkop na inaasahang
kakayahan at kilos (developmental tasks) sa panahon ng pagdadalaga /
pagbibinata ay nakatutulong sa: a. pagkakaroon ng tiwala sa sarili
*How will you apply the lesson on solving quadratic equation to real life
situation?
H. Making
generalization and
abstraction about the
lesson
Guide Question for Generalization:
1. What are the steps in finding the vertex?
2. How do you determine the direction of opening of the parabola, the vertex,
the axis of symmetry and minimum or maximum value, of the quadratic
functions?
F. Evaluating learning Direction: In a ½ sheet of paper answer the following questions.
Determine the direction of opening of the parabola, the vertex, the axis of
symmetry and minimum or maximum value, of the following quadratic
functions.
Quadratic Function Opening
of
Parabola
Vertex Axis of
symmetry
Minimum
or
maximum
value
1. f(x) = (x - 3) 2
2. f(x) = -(x +2) 2 + 1
3. f(x) = 3x 2 - 6x + 5
G. Additional activities
for application or
remediation
DIRECTION: Sketch the graph following quadratic functions. Determine
the direction of opening of the parabola, the vertex, the axis of symmetry and
minimum or maximum value of the following quadratic functions.
1. f(x) = x 2 + 3x – 6
2. f(x) = 2x 2 + 2x - 7
3. f(x) = x 2 - x - 10
