- 1. t LESSON PLAN IN MATH 6
- 2. Objectives: 1. Find the percentage when the rate andrate and base are given - Write the data for rate and base using Techan’s triangle - Strive for one’s best
- 3. content: Skill: - Find the percentage when the rate and base are given Reference: - BEC PELC II 3.2.1 and 3.1Value: - Striving for one’s best/ perseverance
- 4. preparatory activities:1. Mental Computation Drill on changing percent to ratio, decimal to percent, fraction to percent, and vice versa
- 5. percent to ratio:6% =
- 6. decimal to percent:1.2 =
- 7. Fraction to percent:3/4 =
- 8. Percent to decimal:25% =
- 9. ratio to percent:1:2 =
- 10. Completethe table:DECIMAL FRACTION RATIO PERCENT 2.5 2/5 1:5 65%
- 11. preparatoryactivities: What’s your target2. 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 theteacher during the discussion of the lesson.When they were given a five item test, hisgrade was 80%. How many correct answersdid 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 youalso be listening intently to theteacher? Why? 5. Do you think you can get ahigher 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 wordexpression 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 ofthem are present? How many are absent? b. Rhoda’s allowance for the day isP250. She spends 80% of it and saves therest. How much does she spend? How muchdoes she save?
- 23. evaluation: Answer the following: 1. What is 25% of 4? 2. N is 50% of 2 3. 200% of 3 is what number? 4. 75% of12 is ___ 5. 60% of 30 is N
- 24. evaluation: Answer the following: 6. 30% of 600 is what number? 7. 230% of 90 is N 8. 150% of P400 is ____ 9. ___ is 10% of P1,000,000 10. What is 1% of P1,000?
- 25. ANSWERS: 1. 1 6. 180 2. 1 7. 207 3. 6 8. 600 4. 9 9. 100,000 5. 18 10. 10
- 26. assignment: Complete the table. BASE RATE PERCENTAGE 30 10% 50 60% 60 30% 180 150% 200 75%
- 27. Thanks and God bless you all! See you next time and don’tforget to study your lessons. Do your homework, too.
