B. Recalling/Review
Who among you here can recall about
what we have discussed last
meeting?

Kathy, what have you remembered

Ma'am, our topic last
about the previous topic?
meeting was all about the
different kinds of
quadrilaterals.
Very good!

Our topic last meeting was all about

the Different kinds of Quadrilaterals.

C. Activity Let’s have first an activity.

Activity: “WHAT AM I”
Direction: While the teacher plays
the music, the students will pass the
box to their classmates and whoever
hold the box as the music stops will
choose and answer the statement.
Possible Answers:
I am quadrilateral with opposite
 sides are parallel. What am I? (Parallelogram)

I am a special parallelogram
with 4 right angles. What I am? (Rectangle)

I am a special rectangle that

has 4 equal sides with form
right angles. What am I?
(Square)
I am a parallelogram with 4
congruent sides. What am I? (Rhombus)

I have exactly one pair of

parallel sides. What am I? (Trapezoid)

Very Good Class!

D. Presentation Now, based on our activity, what do

you think will be our lesson for today? Our lesson for today is all
about the Identifying parts
of quadrilaterals.
Very good!

But before we proceed to our

discussion, let us have first the
objectives of our lesson.

Kindly read, everyone.

At the end of the lesson,
pupils will be able to:
a. identify the parts of
a Quadrilateral;
b. draw Quadrilateral;
and
c. work cooperatively
with the group.

D.3 Abstraction I will ask the following question which
must be answer by you.

What are the parts of quadrilateral?

The parts of quadrilateral
are the sides and vertices.
What is quadrilateral? Quadrilateral are the plane
figures with 4 sides and 4
vertices.

Yes, very good

The parts of quadrilateral are sides

and vertices.

Quadrilaterals are plane figures

having 4 sides and 4 vertices.
