11. preparatory
activities:
What’s your target
2. score in a 20-item
test? What passing
grade is it?
(75%, 80%, 90% or
100%)

12. developmental
activities:
1. Pablo listens very well to the
teacher during the discussion of the lesson.
When they were given a five item test, his
grade was 80%. How many correct answers
did Pablo get?

13. Answer the
following
questions:
1. Who listens very well to the
teacher?
2. How many items was their
test?

14. Answer the
following
questions:
4. If you were Pablo will you
also be listening intently to the
teacher? Why?
5. Do you think you can get a
higher grade than Pablo? Why do you
think so?

15. Discussion:
1. What are the given data?
( Lead the pupils to write the
given data inside the Techan’s
triangle)
2. What is the equation for the
problem?

16. translating word
expression Into
Mathematical
expression or
equation
What is 90% of a 50-item test?
or
90% of a 50-item is what?

17. what - can be replaced by any
letter; it is the missing
number
is - can be replaced by equal
sign
of – means multiplication as in
¼ of 20 means ¼ X 20

18. What is 90% of 50?
so N = 90% X 50
N = 0.9 X 50
N = 45
90% of a 50-item is what?
so 90% X 50 = N
0.9 X 50 = N
45 = N

19. practice
exercise:
Solve for the percentage.
a. 36% of 95 is N.
b. 48% of 290 is what number?
c. N is 20% of 8?
d. What is 20% of 8?
e. 60% of 80 is what?

20. generalization:
How do you find the percentage
when the rate and base are given?
P
B R
Techan’s
Triangle

21. generalization:
Multiply the base and the rate
to get the percentage of a number.
P
B R
Techan’s
Triangle

22. application:
a. There are 40 pupils in a
class. Seventy-five percent of
them are present? How many are absent?
b. Rhoda’s allowance for the day is
P250. She spends 80% of it and saves the
rest. How much does she spend? How much
does she save?

23. evaluation:
