A Detailed Lesson Plan in General Mathematics
Topic: Evaluating Functions
Content Standard: The learners master the key concepts of functions specifically on
evaluating functions
Learning Competencies:
 1. Recall the process of substitution;
 2. Identify the various types of functions;
 3. Evaluate functions.
LEARNING ENDSTATES:
What skills & competencies, values & attitudes (7 self-mastery skills) are being developed? To what
degree should students be assessed?
The learner:
Understands key concepts of tests of hypothesis as applied to real-life
problems.
Applies concepts on hypothesis testing on population mean.
Upholds accuracy, validity, and reliability in the application of key concepts
of tests of hypothesis.
Proves and defends chosen statistical models and corresponding
solutions to statistical problems.
Y: Predicts possible outcomes or consequences of problems or situations
based from results on statistical tests.
-making through the study of tests of
hypothesis.
earning to BE: Innovative Statistician

Who are present today?
It’s good to know that many of you are present
this time.
Ok! Have you experienced the feeling of being lost?
Being lost sometimes is bad and sometimes is good. Is good
Students comments their
name in the comment box.
(Some students will raise
their hands)
that being lost is to find yourself.
(The student/s will answer)
Just like evaluating functions, you need to find the unknown
values?
(Student’s answer may vary)
We will find then and proves something after learning the
Evaluating Functions.
You may now sit and listen carefully.
Before we proceed to our new lesson, let us have some mind
game.
Yes, sir!
This classroom strategy enables the learners to become more
engaged in the learning in order to enforce positivity. They will be
more motivation and it fosters controlled competitiveness among
individual learners and as a group.
Puzzle? Place the integers
between -4 and 4 in the
missing spaces so each function
evaluates properly)
So, let us now go to our topic.
ACTIVATE (Creating Focus and Purpose)
This time, you are going to view a power point presentation.
Watch and listen intently because I am going to ask questions after
the presentation.
(This teaching strategy enables the learners to digest information
based on their own understanding through ICT-based learning) Evaluation of a Function.
What did you noticed to the short presentation?
That’s right!
ACQUIRE
(Student’s answer may vary)
(Students will listen)
(The teacher discusses further Evaluating Function)
Let’s start with the terms and symbols which will be used in the lesson.
Variables – x,y,z or any letter
Numbers – 1,2,3,4,……..
Evaluate – find the value of the variables
Types of Functions Read and analyze some of the common types of
functions that you might encounter as you go on with this module.
(Students will listen)
(Students will listen)
(Teaching strategies that develop higher order
thinking skills)
Learning the different types of function is essential in this
lesson. Because you will encounter those types as we
proceed with evaluating functions.
When we say evaluating function, is the process of
determining the value of the function at the number
assigned to a given variable. Just like in evaluating algebraic
expressions, you just need to: a.) replace each letter in the
expression with the assigned value and b.) perform the
correct order of operations in the expression.
APPLY, PRACTICE, FORMATIVE ASSESSMENT
Apply the application of the Continuity of a Function

Directions: Read carefully each item. Use separate sheet for your
answers. Select only the letter of the correct answer for each test item.
SUMMATIVE ASSESSMENT, CLOSURE AND REFLECTION
(Teaching strategies using differentiated, developmentally
appropriate learning experience to address learner's gender,
needs, strengths, interests and experiences.)
(Students will perform the
activities based on their
interests).
Summative Test(printed also in separate sheet)
The learners will answer the
Summative Assessment
The learners will present their
outputs.
‘
Now, let us have an activity. You are going to present your answer
on time.
Activity:
Evaluating Simple Functions Bingo
Before you proceed to the activity, may I present the following
rules: (Clear Expectations of Result: Classroom Management
Strategies)
1.
Participating students will be recognized with points using
a rubric.
2.
Avoid unnecessary noisiness while doing the activity.
Noisy learners will have deductions in terms of the scores.
3.
The activity will be done only for 15 minutes.
4.
All learners must participate in the activity.
This time, you are now ready to do the task.
Here are some enrichment activities for you to work on to master and
strengthen the basic concepts you have learned from this lesson.
Additional activities for application or remediation
Additional activity.
Let’s Compute!
The learners will answer this
activity as a quiz and to be
submitted before going home.
That would be all for now.
Goodbye class!
Remarks
Goodbye and thank you sir.
