III.
PROCEDURE
A.
Preparatory Activities
1. Motivation
(Pick-up Lines)
a) Divide the class
into groups of 5.
b) Each group will be
provided a picture of an electric appliance.
c) Each group must
think of a pick-up line related to the appliance to be shared to the class.
(Example: TV ka ba?
Kasi ikaw ang nagpapaligaya sa akin.)
·
After
the activity, raise the following questions:
a) Do you have these
appliances at home?
b) What makes these
appliances work?
c) How much
electricity do you think your family consumes in a month?
B.
Developmental Activities
1. ACTIVITY
·
Let
learners watch a video clip on electric meter reading.
·
Have
them note on the following guide questions:
a. What is
kilowatt?
b. How is dial electric
meter different from digital electric meter?
c. How do we read a
dial electric meter?
·
Discuss
their answers after the watching the video clip.
·
Let
them practice reading analog electric meter.
2.
ANALYSIS
·
Show
a sample electric bill.
·
Let
learners focus on the Present and Previous Reading and Electric Consumption.
·
Let
them analyze and discuss among themselves the following question:
How do we solve electric consumption?
·
Have
them accomplish the following table.
|
Present
Reading |
Previous
Reading |
Electric
Consumption (kwh) |

|
1) 3456 |
3424 |
|
|
2) 1125 |
1120 |
|
|
3) 2355 |
2200 |
|
|
4) 7845 |
7799 |

3.
ABSTRACTION and COMPARISON
·
Based
on their answers, let them create the formula in solving electric consumption.
Electric
Consumption = Present Reading – Previous Reading
·
Each
group will present their discovery and answers to the class.
4. APPLICATION
·
Solve
the following problems:
a) Dalisay
Family’s present reading is 4567 while their previous reading is 4434. What is
the electric consumption of Dalisay Family for that month?
b. Mrs. Sotto kept
a record of her family’s electric consumption. In March, the electric meter
reads 3456. In April, the electric meter reads 3588. What is their electric
consumption during this period?
Value
Focus:
·
Let
learners reflect on the following questions:
a) Why is electricity
important?
b) Why do we need to
save electricity?
c) How can we save
electricity?
5.
Generalization
Ask:
How do we
read/interpret electric meter?
How do we solve electric
consumption?
What is the unit
of measurement for electric consumption?
IV.
EVALUATION
A. Read the
following electric meters:
1.
2.
3.
B. Solve the
following problems:
4. What is the
electric consumption of a family with Present Reading of 1569 and Previous
Reading of 1421?
5. Lopez Family’s electric
meter reads 7456 in November. In December, the electric meter reads 7623. What
is their electric consumption during this period?
V.
ASSIGNMENT
·
Have
learners do the following:
If you
are a scientist, what would you invent in order to generate electricity? Draw
your ideas in a short bond paper to be shared in class next meeting.
