Teacher’s Activity
A. Routine
1. Greetings
Good morning, class!
2. Prayer
Let us pray.
Dear God, our Father Almighty,
we thank you for this wonderful day.
We ask for your guidance. Give us
strength and wisdom to become a
fruitful servant of God. Amen.

I’m like the box of tissue when you
say achoo. (Ngee)
C. Review
What are the shapes of the ff:
Triangle, square, rectangle
D. Motivation
The teacher will choose three students
to join her to buy three items.
The vendor will come out from the
store with the 2D item and a box full
of 3D items.
The vendor will let the students to get
the 2D items that they will buy. Then
pick an item from the box of 3D
items that has the same shape of the
2D item.
The teacher will let the students
describe the 2D and 3D figures.
E. Presentation
Plane figures have only two
dimensions, the length and the width.
Spatial figures have three dimensions,
the length, width, height or thickness.
What are spatial figures again?
Let us discuss the first spatial figure.
Generally, this is called a prism.
Prism is a space figure which has
parallel and congruent faces. And
they are named according to the
shape of their bases.
What is the shape of its base?
So, how is this prism called?
It has bases, faces, edges and vertices.
So, let us first discuss the bases.
The top and the bottom of this figure
are its bases.
Each flat surface of solids is called a
face.
We call the sides of the faces as
edges.
And the point where the two edges
meet is called vertex.
3 dimensional figures
Rectangle
Rectangular prism
So, let’s have another prism.
Where are the bases of this figure?
If this is the base of the prism, what is
its shape?
How do we call this prism?
In this prism, where are the lateral
faces?
What is the shape of the lateral faces?
So, it means that triangular prism
have triangular base with rectangular
faces.
Point and count the edges of this
figure.
Where are the vertices?
Could you please count?
Triangle
Triangular prism
Rectangle
Our next prism is this one.
Can you describe it?
This kind of prism is special and it is
called as cube.
Where are the faces?
What can you say about it?
How many bases does this cube has?
Point it.
How many edges and vertices does it
have?
Two
There are 12 edges and eight vertices.
Let us now proceed to this figure
which is Cylinder.
What comes into your mind when
you see this figure?
Cylinder is made up of a curved
surface. So, in this figure where is the
curved surface?
There are two congruent circular
bases. Could you please point it?
And the bases are flat surface.
can, tissue, etc.
Let us now proceed to this figure.
What comes into your mind when
you see this figure?
This figure is called a cone.
It is made up of a curved surface and
one circular base.
Did you notice the difference of a
cylinder and a cone? What is it?
Ice cream cone, party hat, etc.
A cylinder has two congruent circular
bases while the cone has only one circular
base.
The base is joined by a curved surface
to a point called vertex.
The base is a flat surface.
Pyramids have polygons as their base.
The faces are triangles with a
common vertex. They are named
according to their bases.
How many bases does a pyramid
have?
How many faces does it have?
How about the edges?
How many vertices?
One
Four
Eight
Five
Our last figure is this one.
This is a sphere.
Does it have a base?
Does it have a flat surface?
Does it have edges?
Does it have a vertex?
Correct. Give some objects that look
like a sphere.
F. Generalization
The Spatial Figures are Rectangular
prism, Triangular prism, Cube,
Cylinder, Cone, Pyramid, and Sphere.

Give example of actual object for the
following spatial figures.
Group A
Rectangular and triangular prism,
cube, cylinder
Group B
Cone, pyramid, sphere
