C.
Activity
Before we proceed to our discussion, let’s
have
first an activity.
I will flash some statements. All you need to do
is to identify the underlined statement whether it
is hypothesis or conclusion.
Write
P
If the underlined statement is
hypothesis
and
Q
if it is
conclusion.
I’ll give you 1 minute
on each statements to
complete and type your answer on the comment
section below.
Is that clear?
(The teacher will flash the statements.)
C.
Activity
Yes Ma’am.
(The students will answer the
following
statements.)
D.
Analysis
-
What did you do in the given activity?
What have
you noticed to the given
statement
?
Can you now identify what is the
hypothesis
and
conclusion?
D.
Analysis
We identify the
underlined statement
whether it is hypothesis
or
conclusion.
The statement we
answered is an example
of the hypothesis and the
conclusion.
Yes Ma’am.
E.
Abstraction
E.
Abstraction
From the given activity you’ve just
encountered
,
the hypothesis and the conclusion
or the “if
then” statements.
You are alr
eady familiar with the concept of
this in your daily lives.
Have you ever had a
parent say any of the
following... “If you clean your room, then you
can go out with your friends.” “If your module
is done, then you can play with your mobile
phone.” “If you d
o your chores all week, then
you can get your allowance.”
Those are an example of the hypothesis and the
conclusion or the “if
then”
statements.
These statements is composed of two (2)
clauses. From the given examples, what do you
think is the two
clauses?
Very well said.
The
if
6
clause is the hypothesis
and the
then
clause is the conclusion
.
We can denote a letter for each clause,
p
for
the if
clause or the hypothesis and
q
for then
clause or the conclusion.
The statement is in the form, “If
p
then
q
.”
or
“
p
implies
q.”
-
Example,
If you clean your room, then you
can go out with your friends.
What do you think is our hypothesis (p)?
How about the conclusion (q)?
Very good.
The measure of an acute angle
is between 0
and 90.
We can w
rite th
e statement in the if
then form.
If the angle is acute, then its measures is
between 0 and 90.
Try to answer this example
Two distinct planes intersect.
The intersection is a line
Since
you’ve already
identified
and determine
the relationship of the hypothesis and
conclusi
on.
Yes Ma’am.
I think the two clauses are the if
clause and the then
clause.
You clean your room.
You can go out with
your friends.
If two distinct planes intersect,
then their intersection is a line.
F.
Generalization
I know you’ve learned a lot from this
F.
Generalization
(Students will raise their
discussion, so anyone who can
summarize the
Lesson?
(Call two students
to generalize the topics.)
Very good.
Are they any question?
What is hypothesis means?
Very good.
How about the conclusion?
Very good.
You all did understand the lesson.
what are you feeling right now?
kindly use our in call messages on what you are
feeling right now
if you are happy kindly sent a “happy emoji , if
you are feeling loved sent a “heart emoji”
hands)
(None Ma’am)
It states the given facts that
are assumed to be
true.
What needs to be proven or
established.
(students will sent a different
emojis)
G.
Application
I will group you in to four (4) groups.
I will flash some statements. Each groups
should be identify the hypothesis and the
conclusion of each statements.
Each group should have one repr
esentatives.
The representative
will discuss the given
statements
belong.
IV.
Evaluation
In any sheet of paper, write the hypothesis
and conclusion of an “if
then” statements.
1.
If two planes intersect, then their
intersection is a line.
Hypothesis:
________________________________
___
Conclusion:
________________________________
___
G.
Application
(The students will listen
to the instruction.)
2.
If today is Monday, then tomorrow is
Tuesday.
Hypothesis:
___________________________
Conclusion:
_
__________________________
3.
If two angles are congruent, then they
are vertical.
Hypothesis:
___________________________
Conclusion:
___________________________
4.
If a number is a whole number, then it is
an integer.
Hypothesis:
_______________________________
Conclusion:
_______________________________
5.
If a number is an integer, then it is a
rational number.
Hypothesis:
______________________________
Conclusion:
______________________________
V.
Assignment
Identify the Hypothesis
and the Conclusion
in the following statements:
1.
If a polynomial has six sides, then it is a
hexagon.
2.
If a figure is a triangle, then it has three angles.
3.
If 3x = 24, then x = 8.
4.
If two angles are congruent, then they are
vertical.
5.
If two lines are skew, t
hen they do not intersect.
