Percent math 6

1. 1. t LESSON PLAN IN MATH 6
2. 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. 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. 4. preparatory activities:1. Mental Computation Drill on changing percent to ratio, decimal to percent, fraction to percent, and vice versa
5. 5. percent to ratio:6% =
6. 6. decimal to percent:1.2 =
7. 7. Fraction to percent:3/4 =
8. 8. Percent to decimal:25% =
9. 9. ratio to percent:1:2 =
10. 10. Completethe table:DECIMAL FRACTION RATIO PERCENT 2.5 2/5 1:5 65%
11. 11. preparatoryactivities: What’s your target2. score in a 20-item test? What passing grade is it? (75%, 80%, 90% or 100%)
12. 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. 13. Answer the following questions: 1. Who listens very well to the teacher? 2. How many items was their test?
14. 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. 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. 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. 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. 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. 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. 20. generalization: How do you find the percentage when the rate and base are given? P B R Techan’s Triangle
21. 21. generalization: Multiply the base and the rate to get the percentage of a number. P B R Techan’s Triangle
22. 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. 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. 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. 25. ANSWERS: 1. 1 6. 180 2. 1 7. 207 3. 6 8. 600 4. 9 9. 100,000 5. 18 10. 10
26. 26. assignment: Complete the table. BASE RATE PERCENTAGE 30 10% 50 60% 60 30% 180 150% 200 75%
