GRADE 8 | MATHEMATICS
UNIT 1
Factoring
Mathematics relies on logic and creativity, and it is studied both for its theoretical and
practical applications. For some people, not just the
professionals, the pursuit to understand the essence of
mathematics lies in the study of patterns and relationships.
For grade 8 students, the pursuit to study mathematics starts
with the understanding of the concepts of polynomials.
For some, it is not outright clear when or where the application of the study polynomials
can be readily applied. However, even the simplest tasks or scenarios can be modeled
using polynomials.
Have you ever wondered how architects maximize and design a
certain floor plan of a house or a building? …or how an engineer
computes for the right mixture of cement and gravel to be used for
the foundations of skyscrapers and other infrastructures? …or simply
how a carpenter builds a cabinet or drawer using limited supplies?
In this unit, you will learn about the different factoring techniques that
will be useful in simplifying polynomials as well as their applications in the real world.
