2. I. Intended Learning Outcomes
Through varied learning activities, the grade 8 students with at least80 % ofaccuracy shall
able to:
1. Restate the formula of the mean of ungrouped data
2. Share data from one another to gather the data values
3. Solve the mean ofthe ungrouped data that they will gather
4. Interpret carefully the computed mean
II. Learning Content
A. SubjectMatter
Arithmetic Mean of Ungrouped Data
B. Skill Focus
Gathering, Solving and Interpreting
C. Reference
Spiral Math 8 by Jose Maria L. Escaner and et. al., pages 207 – 209 Advanced
Algebra, Trigonometry and Statistics IV by Soledad Jose –Dilao and et. al., pages 258-
259, Math Learners’ Module 8
D. Materials
Visual aids, meter sticks, weighing scale, chalkboard,Projector and strips ofpaper
III. Learning Experiences
A. Activity
The students will group themselves into five members. Within 3 minutes, they will
ask one another their daily allowance Budget. Then, after they gather the data, they will
write them down on a piece ofpaper.
B. Analysis
 What did you discover in the activity with regards ofyour classmates’
allowance?
 What have you observed to the data you gathered?
 How will you find the average budgetallowance ofyour group?
C. Abstraction
From the gathered data, students shall compute the mean with the given formula.
Mean =
𝑠𝑢𝑚 𝑜𝑓 𝑡ℎ𝑒 𝑑𝑎𝑡𝑎 𝑣𝑎𝑙𝑢𝑒𝑠
𝑇𝑜𝑡𝑎𝑙 𝑛𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑑𝑎𝑡𝑎 𝑣𝑎𝑙𝑢𝑒𝑠
Mean is one ofthe measures ofCentral Tendency which is defined as summing
up the data values and dividing by the number ofdata values.

3. D. Application
Boys
Students will group themselves according to their gender and they will getthe
measurementof their heightusing the meter stick. Then, they will solve the mean of the
group.
Set B
Students will group themselves according to their gender and they will getthe
measurementof their weightusing weighing scale. Then, they will solve the mean of the
group.

salary? Illustrate your answer through ladder diagram.
4. Is finishing your studies enough for you to have a good living and to make your life more
convenientand more comfortable? If no, what are the values you should have for you to
achieve your goals in life?

A week before the discussion of this lesson, I
asked my students what subject areas they found
most challenging and what areas they were easier to
comprehend. Majority of them said that Math and
Science were the two subjects they found difficult
while TLE, Aral Pan and ESP were the areas they
found lighter. Thus, I incorporated my Math Lesson to
these subject areas.
In my first activity, I incorporated TLE specifically,
the Table Setting and Computer Hardware, I knew
these two concepts were quite familiar with my
students as they always encounter these things in
their daily life.
To make the activity more challenging , I put up the
Science Lesson specially the Laboratory Apparatus
for I knew, some of my students were heard these
things for the first time.
To catch my students' interest and enthusiasm to
learn, I related the concept of my topic to a
relationship or love life. I added some hugot lines for I
noticed that in every time I crack a joke , my class
feels alive and less lethargic. Hence, the values
integration applied in my Math lesson.
In addition , I integrated my lesson to Araling
Panlipunan which involved a community and a family.
Through this, I made my lesson lighter and easier to
comprehend.
My students were also engaged with one another as
they asked their classmates' birthdays . I heard lately
that some students were fighting each other over
small things so, to make them closer and more
comfortable to one another, I put up this activity for
this purpose.
I ended my lesson by giving them assignment to ask
and to interview the community member about the
nature of their work , salary per month and number of
hours of work. I let them do this activity not only for
the integration of Math lesson, but also to make them
realize the importance of education in their life. I want
them to reflect that finishing their studies make them
more comfortable and more convenient in living.
