This Teacher‟s “Module in solving Polynomials” is part of the requirements in
Educational Technology 2 under the revised curriculum for Bachelor in Elementary
Education based on CHED Memorandum Order (CMO)-30, Series of 2004. Educational
Technology 2 is a three (3)-unit course designed to introduce both traditional and innovative
technologies to facilitate and foster meaningful and effective learning where students are
expected to demonstrate a sound understanding of the nature, application and production of
the various types of educational technologies.
The students are provided with guidance and assistance of selected faculty
members of the College on the selection, production and utilization of appropriate
technology tools in developing technology-based teacher support materials. Through the
role and functions of computers especially the Internet, the student researchers and the
advisers are able to design and develop various types of alternative delivery systems.
These kinds of activities offer a remarkable learning experience for the education students
as future mentors especially in the preparation and utilization of instructional materials.
The output of the group‟s effort on this enterprises may serve as a contribution
to the existing body instructional materials that the institution may utilize in order to
provide effective and quality education. The lessons and evaluations presented in this
module may also function as a supplementary reference for secondary teachers and
students.

Polygons are very useful graphical tool. Three- - dimensional shapes solids can easily be approximated
with few polygons, and, when good shading and texturing are applied, they can look reasonably realistic. They can be
drawn quickly and cover up very little storage space. Polygons are enclosed area bounded by at least three sides. A
polygon can be defined as a set of points or a set of line segments. The order in which the set of points are listed is
important. Different orders mean different polygons. These two polygons are made from the same set of points, listed in
a different order.
Space figures are figures whose points do not all lie in the same plane. In this unit, we'll study the
polyhedron, the cylinder, the cone, and the sphere.
Polyhedrons are space figures with flat surfaces, called faces, which are made of polygons. Prisms and pyramids are
examples of polyhedrons.
Cylinders, cones, and spheres are not polyhedrons, because they have curved, not flat, surfaces. A cylinder has two
parallel, congruent bases that are circles. A cone has one circular base and a vertex that is not on the base. A sphere is
a space figure having all its points an equal distance from the center point.
The space that we live in have three dimensions: length, width, and height. Three-dimensional geometry,
or space geometry, is used to describe the buildings we live and work in, the tools we work with, and the objects we
create.
First, we'll look at some types of polyhedrons. A polyhedron is a three-dimensional figure that has
polygons as its faces. Its name comes from the Greek "poly" meaning "many," and "hedra," meaning "faces." The ancient
Greeks in the 4th century B.C. were brilliant geometers. They made important discoveries and consequently they got to
name the objects they discovered. That's why geometric figures usually have Greek names!
We can relate some polyhedrons--and other space figures as well--to the two-dimensional figures that we're already
familiar with. For example, if you move a vertical rectangle horizontally through space, you will create a rectangular or
square prism.
If you move a vertical triangle horizontally, you generate a triangular prism. When made out of glass, this type of prism
splits sunlight into the colors of the rainbow.
Now let's look at some space figures that are not polyhedrons, but that are also related to familiar two-dimensional
figures. What can we make from a circle? If you move the center of a circle on a straight line perpendicular to the circle,
you will generate a cylinder. You know this shape--cylinders are used as pipes, columns, cans, musical instruments, and
in many other applications.
A cone can be generated by twirling a right triangle around one of its legs. This is another familiar space
figure with many applications in the real world. If you like ice cream, you're no doubt familiar with at least one of them!
A sphere is created when you twirl a circle around one of its diameters. This is one of our most common
and familiar shapes--in fact, the very planet we live on is an almost perfect sphere! All of the points of a sphere are at
the same distance from its center.
There are many other space figures--an endless number, in fact. Some have names and some don't. Have
you ever heard of a "rhombicosidodecahedron"? Some claim it's one of the most attractive of the 3-Dimensional figures,
having equilateral triangles, squares, and regular pentagons for its surfaces. Geometry is a world unto itself, and we're
just touching the surface of that world. In this unit, we'll stick with the most common space figures.

At the end of the workbook, students are expected to:
1. define what polygon is;
2. know the different formulas in areas of polygons, surface areas and
volumes of space figures;
3. exercise the ability of the student in solving problem;
4. solve the areas of polygons;
5. solve the surface areas and volumes of space figures;
6. develop the skills of the students in solving problems involving different
formulas;
7. solve practical problems dealing with the different formulas in polygons
in easy way and less hour; and
8. formulate their own formulas in getting the areas of polygons, surface
areas and volumes of space figures.
