2. Review
Yesterday we discuss the adding integers. Right?
So I guess all of you can answer this equation
Yes Ma’am!
(call a student who want to answer the equation)
1. (-8) + (-7) =
2. (+11) + (+23) =
3. (-43) + (+17) =
4. (+59) + (+73) =
5. (+102) + (-102) =
-15
+34 or 34
-26
+14 or 14
0
C. Developmental Activities:
1. Motivation
I have here a big box inside of this box has different
shape all you have to do is to pick one shape in this
box and tell to everyone what kind of shape did you
pick.
Is that clear?
So who wants to pick first in my big box? Anyone?
Cube
.
sphere
cone

cylinder
cube
cone
cylinder
2. Discussion
Can you guess what is our lesson for the day?
Very good!
So how we will describe the solid figure?
Solid figure Ma’am
I have here a box.
(Show them a big box.)
What is the shape of the bottom part of a box?
Is it the same with the shape of the top part?
Rectangle
yes!
What is the shape of the right side of the box?
Does it have with the same shape with the one on
the left side?
Square
Yes!
Do the back and front sides of the box have the
same shape?
Yes!
So how many faces does the box have?
6 faces ma’am
Very good!
How many edges that the box have?
12 edges Ma’am
Very good!
How about vertices? How many vertices that the
box have?
8 vertices
Very good!
Thus the box has three- dimensional object?
Yes!
Because it has length
width and height.
Very good!
So how we will describe a solid figure?
Very good!
Solid figure has threedimensional object if
they have length, width
and height.
So class this means that This box is a solid figure
called rectangular prism, because of its rectangular
base, has 6 faces, 8 vertices and 12 edges. That
you said a while ago.
So what is prism?
(one student will read the definition of a prism)
A Prism is a polyhedron that has two congruent
parallel faces called base.
When we say polyhedron this means a solid figure
whose side are polygon. Each side is called faces.
Two faces that intersect in a line segment is called
an edge. And two edges that intersect in a point is
called a vertex.
(The teacher pointed out where’s the faces edges
and vertex in a box)
A Prism is a polyhedron
that has two congruent
parallel faces called
base.
When we say two congruent parallel faces called
base, meaning to say two same bases was aligned
in bout side.
Can you follow?
Yes Ma’am
I have here some prism that was named according
to the shape of its base.

A cube is a
prism with
a square
base. all its
faces are
square
Pentagonal Pentagonal 5
Has two
Prism
pentagonal
bases and
five
rectangular
lateral
faces.
The lateral faces are the faces that join the base of a solid
figure. Always remember that each faces is a polygon.
Is that clear?
I have here another solid figure can you tell me what is the
name of this solid figure?
Yes ma’am
This are the clues how will you observe a figure
1. The sides are all polygon
2. The figure is a prism
3. Its base are hexagons
The figure is a
hexagonal Prism
8 faces
18 edges
12 vertices
How many faces?
How many edges?
How many vertices?
Another prism is pyramid which is also named according to
the shape of its base.
(one student will read the definition of the pyramid)
A pyramid is a polyhedron whose base is a polygon and the
lateral faces are triangles.
Meaning to say if the prism has 2 equal bases the pyramid
has only one base but the lateral faces are triangle.
Is that clear?
Yes Ma’am
Here are some example of pyramids that was name according
to the shape of its base.

Can you name the figure? Count the number of faces, edges
and vertices.
This are the clues
1. The lateral faces are all triangles
2. The figure is a pyramid
3. The base is a pentagon
Very good!
Other solid figures have curved surfaces

3 .Generalization:
What is solid figure?
Very good!
Can you give me some example of solid figure?
Solid figure has threedimensional object if
they have length, width
and height.
Hexagonal prism
Rectangular prism
Triangular prism
Square pyramid
Cone
Sphere
Cylinder
Etc.
Okay very good!
4. .Application:
(The class will group into 5 group)
What we should do when doing an activity?
