DETAILED LESSON PLAN IN MATH 4
I. OBJECTIVES
At the end of the lesson, the pupils are expected to achieve at least a 75% proficiency level in
the following behavior:
Cognitive: Visualize the perimeter of any given plane figure in different situations;
Psychomotor: Measure the perimeter of any given closed figure using appropriate tools; and
Affective: Show accuracy in counting.

III.LEARNING EXPERIENCES
A. Routine Activities
1.Greetings
"Good morning, Class!"
"Good morning, Teacher Kyla!"
"How are you today?"
"We are okay teacher!"
"That is good to hear!"
2. Checking of Attendance
"Before our lesson begin, let me know who did not
attend on our class for today."
"Group 1, did everyone attend in your group?"
"Very good! Group 2, is everyone attend in the
group?"
"Yes, teacher!"
"Yes teacher, we are complete"
"Very good also, group 2. Group 3, did all of you
also attend?"
"Yes teacher, we are also complete"
"Wow, you'll are very good. Now I want you to
watch the video that I will play so that we can be
lively and have an energy for our discussion for
today, is that ok class?"
"Yes, teacher!"
B. Preparatory Activities
1.Drill
"Okay class, we have an energy now for our
discussion. So now, what do you think is a unit of
measurement and measuring tool that is appropriate
for the following.
1.distance between buildings
2. sides of a handkerchief
3. length of a safety pin
(The students will participate)
4. length of a ballpen
5. edge of a table
6. sides of the blackboard
2. Motivation
Show a plain handkerchief.
What is the shape of these handkerchiefs?
It’s square, Teacher!
Do you carry your handkerchief every day?
Sometimes teacher I carry my
handkerchief, but sometimes I forgot it in
our home!
What are the uses of a handkerchief?
The use of the handkerchief is to wipe the
dirt’s or sweats of our face Teacher!
What other shapes do you know aside from square?
I know rectangle, circle, triangle or kite
teacher!
C. Lesson Proper
1. Presentation
Study the figures.
2. Discussion
How many sticks do you think are put around each
closed figure? You can count the sticks around each
figure to find the perimeter. In the figure A, how
many sticks are in there?
In figure A Teacher, there are 12 sticks.
So, I think the perimeter is 12 units.
Wow, very good! How about in Figure B, how many
sticks are in there?
In figure B Teacher, there are 12 sticks.
So, I also think the perimeter is 12 units.
Wow, you’re also very good! How about in the
Figure C, how many sticks do you think are in there? In figure C, there are 6 sticks Teacher. So,
the perimeter is 6 units because there are
6 sticks.
You’re correct. How about in the Figure D, how
many sticks are in there?
In figure D Teacher, it has 4 sticks. So, the
perimeter is 4 units.
Wow, very good. How about in the Figure E, the last
shape that we have?
If you notice the measures of all sides of a polygon
are added to find its perimeter. Therefore, perimeter
is the distance around a polygon.
Find the perimeter of the following figures by
counting the squares.
In figure E Teacher there are 13 sticks. So,
the perimeter is 13 units.
3. Assessment
Find the perimeter of the figure in each grid.
4. Application
After our discussion, we can now have a little
activity that can know if you learn something today,
Yes, Teacher.
understand class?
Do what is being asked using a paper grid.
1. Draw a square with a perimeter of 12 units.
2. Draw a rectangle with a length of 6 units and
width of 4 units.
3. Draw a trapezoid with a height of 7 units and
bases of 3 units and 5 units.
4. Draw a parallelogram with length of 5 units and
width of 4 units.
5. Draw a rhombus with a side of 16 units.
5. Generalization
The perimeter of a shape is the measurement of the
total length of the outline of the shape. Do you
Yes, Teacher!
understand, class?
IV.EVALUATION
And now that we finish our discussion, let’s have
some activity that I know you can enjoy. If each
square is 1 cm by 1 cm (shown below), find the
perimeter for the shapes shown below.
