2. A. Activity
Okay class, can you tell me what’s on
the picture?
Correct! Have you seen an airplane in
real life?
Have you ever ridden an airplane?
Raise your hands if you have.
Now, to those who haven’t do you
want to ride one in the future?
Class, I will give you a text and you
have to read it silently. The title of the
text is “The First Plane”. I will give you
5 minutes to read.
The First Plane
The first plane was designed by Wilbur
and Orville Wright. The day they tried
to fly it; it was unable to fly high. They
knew that the design was imperfect.
The brothers were unhappy, but they
also knew that flying was impossible.
They replaced their old design with a
new one, and it proved to be a big
success.
Okay, everyone 5 minutes is done.
Did you understand the text?
Really? If that’s so let me ask a few
questions to you all.
First, who designed the first plane?
Very Good!
Next, what happened to the first plane
they designed?
Correct!
What did they do to make the plane
work?
That’s right!
Very good class! You understood the
text very well.
Now, let’s proceed to the main topic of
today’s lesson.
B. Analysis
Today, our topic is “Identifying
unfamiliar words through structural
analysis using prefixes.”
First, let us define prefixes.
Can someone read the definition of
prefixes?
Yes, Ryan?
Airplane.
Yes, teacher!
Yes!
Yes Ma’am.
Ma’am! Wilbur and Orville Wright.
Ma’am! It failed; it wasn’t able to fly.
The fixed it and improve the design!
Ma’am!
3. Very Good!
According to the definition a prefix is a
syllable or a word that is added before
a root word or base word. Class,
remember that when a prefix is added
to a root word the meaning of it will
change. Now, we are going to discuss
the 4 basic prefixes; un-, im-, dis-, and
re-.
Let’s start with prefix “un-.” The
meaning of this prefix is “not”. Let’s
take 2 examples in order for us to
understand. Here’s an example,
unbelievable and unhappy.
What is the root word of
unbelievable?
Correct!
Class, what happened when we put
the word “un- “in the root words?
Exactly! Let’s proceed to unhappy.
What is the Root word?
Let’s use unhappy in a sentence.
King lion becomes unhappy. What
happened to king lion?
If we are going to take out the prefix
to the root word, what would be the
message of the sentence?
Yes! So meaning to say when a prefix
is added to a root word the meaning
will be change. Here’s a couple of
words with prefix “un-“ , unfair,
uncover, unlock, unequal, unkind,
unpack, unhappy. Who can give a
root word that prefix “un-‘’ can be
attach?
Very good? What else?
Very good! Let’s move to prefix “im-“.
The meaning of this prefix is ‘’not’’.
Here’s an examples, imperfect and
impossible. In order to understand it,
let’s use them in a sentence. Let’s
take impossible first. What is the root
word?
Exactly! To defeat king lion is
impossible. Meaning to say?
Yes! Second example is imperfect.
What is the root word?
Exactly! Let’s use this in a sentence
Carl gets imperfect score in
A prefix is a word added to the beginning of a
root word.
Believable!
The meaning changed; it becomes the
opposite of the root word.
Happy!
He becomes lonely.
King lion becomes happy.
Un+safe=unsafe.
Un+just=unjust
Yes, Ma’am.
Possible.
To defeat king lion is not possible.
Perfect.
4. mathematics. What happened to
Carl?
Very good! If we take out prefix “im”
would be the message?
Yes! Here are some words containing
prefix “im-“, impractical, immortal,
improper, impossible, imperfect,
immature, impartial, impatient,
immortal.
Who can give a root word that prefix
“im-“can be attach?
Very good! What else?
Awesome! Let’s proceed to the next
prefix which is “dis-“ and it’s meaning
is the same to prefix ‘’un-‘’ and ‘’im-‘’.
Yes. Let’s take 2 examples and let’s
use it in a sentence. Here’s the 2
examples, dislikes and disagreed.
First, let’s take dislikes. What is the
root word?
Very good! Mark dislikes the dress of
his sister. This means that?
Exactly! Second example, Bryan
disagreed Mark’s plan. We used the
word disagreed, what is the root
word?
Very good! So, what is the message
of the sentence?
Yes! Here are some examples of
words containing prefix ‘’dis‘’, distrust,
disloyal, disgrace, disconnected.
Who can give a root word that prefix
“dis-‘’ can be attach?
Very good! What else?
Awesome! Now, let’s proceed to the
last prefix. The meaning of this prefix
is different from the 3 prefixes that we
discussed a while ago. This prefix
means ‘’again’’ and this prefix is no
other than “re”.
Here are the examples, rejoins and
rebuilds. To understand it better let’s
use them in a sentence. Let’s take
first rejoins. What is the root word?
Very good! Bryan rejoins with the
basketball dunk competition. The
sentence emphasize that Bryan?
Correct! Second example, Bobby the
builder rebuilds his house. We used
the word rebuilds, what is the root
word?
His score was not perfect.
Carl gets perfect score.
Ma’am ! Immortal.
Imbalance.
Likes
Mark did not like the dress of his sister.
Agreed.
Bryan opposed Mark’s plan.
Discharge .
Disobey.
Joins.
Joins the dunk compitation again.
Builds.
5. So, what is the sentence all about?
Exactly! Here are some examples of
words containing prefix ‘’re-“,remarry,
rebuild, reappear, reconsider, rejoin,
return, rewrite, rearrange, regroup,
retake.
Who can give a root word that prefix
“re” can be attach?
Very good! What else?
Very good class!
C. Abstraction
What is prefix again?
Very good! What are the prefixes that
we discussed?
Very good! What will happen to a root
word in the presence of prefix?
Exactly!
We need to study prefixes, because it
helps us to understand unfamiliar
words, like the text that we read a
while ago. Also, prefixes help us to
establish a good communication,
because we can understand
unfamiliar words through structural
analysis using basic prefixes.
D. Application
Below are the most common prefixes
un-, in-, dis-, and im-, are often used
to mean “opposite of” or “not”. Use
these prefixes to complete the
thought of the second sentence by
supplying the correct word with the
correct prefix. The italicized
expressions are clues.
1. The princess couldn’t decide who to
marry. She’s still _______________.
2. The prince was not attentive to the
princess. The prince was ________.
3. The curse was quite not possible to
solve. It seemed _______________.
4. The queen did not seem to agree with
her daughter’s plan. She wanted to
_______ but could not stop her.
5. The prince was not able to satisfy the
second witch. The second witch was
________.
Bobby repairs his house again.
Reopen.
Retold.
Is a word part added to the beginning of a
root word.
‘’un-‘’, ‘’im-‘’, ‘’dis-’’ and ‘’re-’’.
The meaning will be change.
6. IV. Evaluation
Pick up the prefix in the box and put it to the appropriate root word in every question.
re- im- un- dis-
1. Everyone is annoyed because Zeus kept on _telling his story again.
