III. Strategy/Procedure
Teacher’s Activity Learner’s Activity
A. Preliminary Activities
a. Greetings
Good morning class, Mabuhay! Good morning, sir!
b. Prayer
Now, let’s start this day with a prayer. Can (Student will lead the prayer)
I request everybody to please stand up,
(student), will you please lead the prayer?
Amen.
c. Classroom Management
Before you take your seats, I want you to
pick up the pieces of paper under or near
your chairs, if none, arrange your chair
properly and organize yourselves.
d. Checking of attendance
For your attendance, Ms. Secretary, can I
have the report of today’s attendance?
Class Secretary: Sir, there is/are no
absentee/s for today.
Okay very good!
B. Review of the Past Lesson
Do you still remember our lesson from
our last meeting? Yes, Sir.
What was our last lesson all about, anyone?
Our last lesson was all about
Multicellular and Unicellular.
What is the difference between Multicellular
and Unicellular?
The Multicellular organisms are life
forms made up of multiple cells that
work together, each with specialized
functions. While the Unicellular is
Unicellular organisms are life forms
consisting of a single cell. These tiny
powerhouses can perform all
Very good, class! It seems like you necessary functions of life within just
understood our previous lesson. Do you have one cell
any further questions or need clarification?
None, Sir.
If none, let us move on to our new topic.
C. Motivation
Yes, sir.
Now class, are you ready to learn a new
lesson today?
Okay, very good! Now, I have here a fun
activity for you. Activity: Where’s the Cell?
I have here some Pictures and all you must do
is to arrange it in its correct order
I will give you. I will only give you 3 minutes
to do the activity. Is that clear class?
You may now proceed doing the activity. Yes, sir!
Now, based on your activity, do you have any
clue what will be our topic? Is there anyone
who would like to guess it?
I think our lesson will be all about the
That’s right, very good! Cell Division.
D. Presentation / Discussion / PowerPoint
For today our discussion is all about Cell
Division. And we have three
objectives.
Student, kindly read the objectives. Objectives:
Understand the stages and
process of Mitosis and Meiosis
Compare and contrast Mitosis
and Meiosis
Recognize the importance of
cell division in growth,
Thank you, Student. development, and
reproduction.
Yes sir!
So, class are you ready to learn new
things today?
Cell division is a fundamental process
Alright! by which cells reproduce and create
new cells.
Now class, when you hear the word Cell
division what comes in your mind first?
Okay very good. It is a fundamental cell
process of an organism.
And when we talk about Cell division, we (if none of the student answer the
have the Mitosis and Meiosis. And when talk teacher will proceed with the
about this, anyone from the class who have discussion)
any ideas?
So, class when we talk about Mitosis and
Meiosis aside from it is the fundamental
process of any living organism both processes
are also crucial for life, each ensuring that
cells grow, develop, and contribute to genetic
variation.
(Look at one another.)
Look at your sit mates.
What can you say about him/her?
Is she/he looks like you?
No.
No. Because we are different in many ways. (Students may answer if they have

happened?
Open wound became closed for some time. (Students may answer if they have

from open to close one. If no one answer, teacher will
proceed)
The reason why we are different from one
another and the open wound healed is because
of cell divides and reproduce. And these ways
are called Mitosis and Meiosis.
(Students may answer if they have
Now, let’s look for the meaning of Mitosis. idea.
So, what is Mitosis? Any Idea? If no one answer, teacher will
proceed)
So, Mitosis is a process of cell division that
results in two genetically identical daughter
cell developing from a single parent cell.
>It means that Mitosis produced two cells,
and each cell has the same number of
chromosomes. The cell duplicates.
Under normal conditions once an animal cell
becomes specialized it can no longer form an
entire organism, however plant cells are
totipotent (which can divide or reproduce
cells) and any cell can form an entire plant.
Remember your Activity earlier class? Yes sir.
Your activity class is all about the phase or
processes that occurs during mitosis.
So how many processes are there on Mitosis (The students raised their hands to
based on your activity earlier? answer)
Sir the Mitosis itself has 6 Phase.
Very Good (Student) so your mitosis itself
has 6 Phase and now let’s now talk about
each one of them.
Interphase: The cell prepares by replicating
its DNA. Yes, sir.
Prophase: Chromosomes condense, and the
nuclear envelope breaks down.
Class what is Chromosomes and what is it
made of? (The students raised their hands to
answer)
Chromosomes are made of DNA and protein
and carry genetic information that is passed
from one generation to the next.
Metaphase: Chromosomes align at the cell's
equator.
Anaphase: Sister chromatids are pulled apart
to opposite poles.
Telophase: Nuclear membranes reform
around each set of chromosomes.
Cytokinesis: The cell splits into two new
cells.
Now class, do you have any questions?
(The students raised their hands for
questions.)
E. Application
Okay, if there are none, let’s now proceed to
the simple activity I prepared for you. This is Yes, sir
to see if you learned something today!
The class will be divided into two groups.
This will be group 1 and group 2.
I will let you choose what phase is you think
the most important one and you will recreate
that using your bodies. And explain why’d
you choose that phase.
Here is what you are going to do.
Direction: Work together with your group
members to correctly place your body to
mimic the shape of the phase that you have
chosen. And the other group should be able to (The 2 groups of students proceed to
identify what phase have you chosen. I will the activity
give you 3 mins to discuss and to practice
your mimicry.
Do you understand the directions, class?
Criteria:
Accuracy of the Shape- 50%
Understanding of Functions - 30%
Teamwork and Participation - 10%
Presentation skills - 10%
Total: 100%
Great job, everyone! All groups did an
excellent job.
F. Generalization It’s all about Cell Division sir.
Okay! Again, what was our lesson all about?
Anyone? Mitosis is a process of cell division
that results in two genetically identical
Very good! daughter cell developing from a single
Again, what is Mitosis class? parent cell.
(The students raised their hands to
answer)
Sir The Mitosis Has 6 Phase
And how many phase are there in your
Mitosis?
(The students raised their hands to
answer)
Sir we have
And what are those processes we have? • Interphase
• Prophase
• Metaphase
Okay, Great job, everyone! So that is our • Anaphase
topic for today. • Telophase
• Cytokinesis
IV. Evaluation
ESSAY
1. Describe the stages of mitosis and explain the key events that occur in each stage.
How do these events ensure accurate division of genetic material?
2. Discuss the role of mitosis in growth and development. Provide examples of how
mitosis contributes to the maintenance and repair of multicellular organisms.
V. Assignment
Using any material e.g., Clay, Sticks, Papers. Make a 3D model of any phase in Mitosis.
