Introduction
As the Commission supports DepEd’s implementation of Senior High School (SHS), it upholds the vision
and mission of the K to 12 program, stated in Section 2 of Republic Act 10533, or the Enhanced Basic
Education Act of 2013, that “every graduate of basic education be an empowered individual, through a
program rooted on...the competence to engage in work and be productive, the ability to coexist in fruitful
harmony with local and global communities, the capability to engage in creative and critical thinking,
and the capacity and willingness to transform others and oneself.”
To accomplish this, the Commission partnered with the Philippine Normal University (PNU), the
National Center for Teacher Education, to develop Teaching Guides for Courses of SHS. Together with
PNU, this Teaching Guide was studied and reviewed by education and pedagogy experts, and was
enhanced with appropriate methodologies and strategies.
Furthermore, the Commission believes that teachers are the most important partners in attaining this
goal. Incorporated in this Teaching Guide is a framework that will guide them in creating lessons and
assessment tools, support them in facilitating activities and questions, and assist them towards deeper
content areas and competencies. Thus, the introduction of the SHS for SHS Framework.
The SHS for SHS Framework
The SHS for SHS Framework, which stands for “Saysay-Husay-Sarili for Senior High School,” is at the
core of this book. The lessons, which combine high-quality content with flexible elements to
accommodate diversity of teachers and environments, promote these three fundamental concepts:
SAYSAY: MEANING
HUSAY: MASTERY
SARILI: OWNERSHIP
Why is this important?
How will I deeply understand this?
What can I do with this?
Through this Teaching Guide,
teachers will be able to
facilitate an understanding of
the value of the lessons, for
each learner to fully engage in
the content on both the
cognitive and affective levels.
Given that developing mastery
goes beyond memorization,
teachers should also aim for deep
understanding of the subject
matter where they lead learners
to analyze and synthesize
knowledge.
When teachers empower
learners to take ownership of
their learning, they develop
independence and selfdirection, learning about both
the subject matter and
themselves.
i
The Parts of the Teaching Guide
This Teaching Guide is mapped and aligned to the DepEd SHS Curriculum, designed to be highly usable
for teachers. It contains classroom activities and pedagogical notes, and integrated with innovative
pedagogies. All of these elements are presented in the following parts:
1. INTRODUCTION
•
Highlight key concepts and identify the essential questions
•
Show the big picture
•
Connect and/or review prerequisite knowledge
•
Clearly communicate learning competencies and objectives
•
Motivate through applications and connections to real-life
2. MOTIVATION
•
Give local examples and applications
•
Engage in a game or movement activity
•
Provide a hands-on/laboratory activity
•
Connect to a real-life problem
3. INSTRUCTION/DELIVERY
•
Give a demonstration/lecture/simulation/hands-on activity
•
Show step-by-step solutions to sample problems
•
Give applications of the theory
•
Connect to a real-life problem if applicable
4. PRACTICE
•
Provide easy-medium-hard questions
•
Give time for hands-on unguided classroom work and discovery
•
Use formative assessment to give feedback
5. ENRICHMENT
•
Provide additional examples and applications
•
Introduce extensions or generalisations of concepts
•
Engage in reflection questions
•
Encourage analysis through higher order thinking prompts
•
Allow pair/small group discussions
•
Summarize and synthesize the learnings
6. EVALUATION
•
Supply a diverse question bank for written work and exercises
•
Provide alternative formats for student work: written homework, journal, portfolio, group/
individual projects, student-directed research project

On DepEd Functional Skills and CHED’s College Readiness Standards
As Higher Education Institutions (HEIs) welcome the graduates of the Senior High School program, it is
of paramount importance to align Functional Skills set by DepEd with the College Readiness Standards
stated by CHED.
The DepEd articulated a set of 21st century skills that should be embedded in the SHS curriculum across
various subjects and tracks. These skills are desired outcomes that K to 12 graduates should possess in
order to proceed to either higher education, employment, entrepreneurship, or middle-level skills
development.
On the other hand, the Commission declared the College Readiness Standards that consist of the
combination of knowledge, skills, and reflective thinking necessary to participate and succeed - without
remediation - in entry-level undergraduate courses in college.
The alignment of both standards, shown below, is also presented in this Teaching Guide - prepares
Senior High School graduates to the revised college curriculum which will initially be implemented by
AY 2018-2019.

The General Mathematics
Teaching Guide
Implementing a new curriculum is always subject to a new set of challenges.
References are not always available, and training may be too short to cover all the
required topics. Under these circumstances, providing teachers with quality resource
materials aligned with the curricular competencies may be the best strategy for
delivering the expected learning outcomes. Such is the rationale for creating a series of
teaching guides for several Grade 11 and 12 subjects. The intention is to provide
teachers a complete resource that addresses all expected learning competencies, as
stated in the Department of Education’s offi︎cial curriculum guide.
This resource is a teaching guide for General Mathematics. The structure is quite
unique, re︎flective of the wide scope of General Mathematics: functions, business
mathematics, and logic. Each lesson begins with an introductory or motivational
activity. The main part of the lesson presents important ideas and provides several
solved examples. Explanations to basic properties, the rationale for mathematical
procedures, and the derivation of important formulas are also provided. The goal is to
enable teachers to move learners away from regurgitating information and towards an
authentic understanding of, and appreciation for, the subject matter.
The chapters on functions are an extension of the functions learned in Junior High
School, where the focus was primarily on linear, quadratic, and polynomial functions.
In Grade 11, learners will be exposed to other types of functions such as piecewise,
rational, exponential, and logarithmic functions. Related topics such as solving
equations and inequalities, as well as identifying the domain, range, intercepts, and
asymptotes are also included.
iv
The chapters on business mathematics in Grade 11 may be learners' ︎first opportunity
to be exposed to topics related to ︎financial literacy. Here, they learn about simple and
compound interest, annuities, loans, stocks, and bonds. These lessons can hopefully
prepare learners to analyze business-related problems and make sound ︎financial
decisions.
The ︎final chapter on logic exposes learners to symbolic forms of propositions (or
statements) and arguments. Through the use of symbolic logic, learners should be able
to recognize equivalent propositions, identify fallacies, and judge the validity of
arguments. The culminating lesson is an application of the rules of symbolic logic, as
learners are taught to write their own justifications to mathematical and real-life
statements.
This Teaching Guide is intended to be a practical resource for teachers. It includes
activities, explanations, and assessment tools. While the beginning teacher may use
this Teaching Guide as a “script,” more experienced teachers can use this resource as a
starting point for writing their own lesson plans. In any case, it is hoped that this
resource, together with the Teaching Guide for other subjects, can support teachers in
achieving the vision of the K to 12 Program.
