1 BSI Workshop: Reading/English/Math PERCENTAGES IN OTHER DISCIPLINES "Come, Watson, come! The game is afoot. Not a word! Into your clothes and come!"

2 BSI Workshop: Mathematics PROBLEM SOLVING INVOLVING PERCENTAGES

3 BSI Workshop: Mathematics WHO ARE THE 99%, 37%, 12%, 0.2%?

4 THE STUDY OF PERCENT STARTS WITH FRACTIONS. BSI Workshop: Mathematics

5 Divide region A into two identical sections.

6 BSI Workshop: Mathematics Did you make the following division?

7 BSI Workshop: Mathematics Divide region B into three identical sections.

8 BSI Workshop: Mathematics Did you make the following division?

9 BSI Workshop: Mathematics Divide region C into four identical sections.

10 BSI Workshop: Mathematics That wasn’t so bad.

11 BSI Workshop: Mathematics Divide region D into seven identical sections.

12 BSI Workshop: Mathematics Was your brain on overdrive?

13 BSI Workshop: Mathematics PEOPLE ARE DIFFERENT, BUT SHARE COMMON FEARS.

14 BSI Workshop: Mathematics FOR ME, IT IS SCARY NURSES.

15 FOR MANY STUDENTS, IT IS MATH and more often than not, we just see the RESULTS. BSI Workshop: Mathematics

16 SYRINGES COME IN DIFFERENT SIZES. LET’S ADDRESS BOTH FEARS.

17 BSI Workshop: Mathematics THE BASIC IDEA BEHIND FINDING A FRACTIONAL PART OF A QUANTITY IS : Find ¾ of 80. 1) FIRST FIND ¼ OF THE QUANTITY. 2) THEN MULTIPLY BY 3.

18 BSI Workshop: Mathematics Find 5/4 of 80. THE CONCEPT REMAINS UNCHANGED EVEN IF THE FRACTION IS IMPROPER :

19 BSI Workshop: Mathematics WHAT IS 92% OF 50? HOW MUCH SALINE SOLUTION IS IN THE SYRINGE? AS DETERMINED BY THE TECHNO-SAVY STUDENT. Percent x Whole = Portion; so 0.92 x 50 = Portion (saline solution) and 0.92 x 50 = 46 ml of saline solution. A SYRINGE CONTAINS 50 ML OF MEDICATION OF WHICH 92% IS SALINE.

20 BSI Workshop: Mathematics MATHEMATICAL SYRINGES IN MATH, ALL SYRINGES ARE PROPORTIONAL.

21 HOW MUCH SALINE SOLUTION IS IN THE SYRINGE? AS DETERMINED BY MATHEMATICAL UNIFORMITY. BSI Workshop: Mathematics The two are proportional. If the unknown, N, represents the amount of saline solution, then 46 ml of saline solution A SYRINGE CONTAINS 50 ML OF MEDICATION OF WHICH 92% IS SALINE. WHAT IS 92% OF 50?

22 SADLY, CHARLIE BROWN UNDERSTANDS PROPORTIONS. BSI Workshop: Mathematics

23 WHAT IS 92% OF 50? ALL THINGS ARE NOT CREATED EQUAL.

24 BSI Workshop: Mathematics HOW MUCH SALINE SOLUTION IS IN THE SYRINGE? AS DETERMINED BY THE LOGICAL VISUALISTS. The left side is divided in 100 sections; so divide the right side into 100 sections or 0.50 each, consider 92 sections, totaling 0.50 x 92 equals 46 ml of saline solution. A SYRINGE CONTAINS 50 ML OF MEDICATION OF WHICH 92% IS SALINE. WHAT IS 92% OF 50?

25 BSI Workshop: Mathematics WHAT PERCENT OF THE SYRINGE IS THE SALINE SOLUTION? AS DETERMINED BY THE TECHNO-SAVY STUDENT. Percent x Whole = Portion; so Percent = Portion ÷ Whole Percent = 48 ÷ 60 = 0.80 = 80%. 48 IS WHAT % OF 60? A SYRINGE CONTAINS 60 ML OF MEDICATION OF WHICH 48 ML IS SALINE.

26 48 IS WHAT % OF 60? WHAT % OF THE SYRINGE IS SALINE SOLUTION? BSI Workshop: Mathematics AS DETERMINED BY MATHEMATICAL UNIFORMITY. If N represents the percentage of saline solution, then 80% saline solution A SYRINGE CONTAINS 60 ML OF MEDICATION OF WHICH 48 ML IS SALINE.

27 BSI Workshop: Mathematics AS DETERMINED BY THE LOGICAL VISUALISTS. The right side is divided in 60 sections; so divide the left side into 60 sections of 5/3 each, consider 48 sections, totaling 48 x 5/3 or 80% saline solution. 48 IS WHAT % OF 60? A SYRINGE CONTAINS 60 ML OF MEDICATION OF WHICH 48 ML IS SALINE. WHAT % OF THE SYRINGE IS SALINE SOLUTION?

28 BSI Workshop: Mathematics AS DETERMINED BY THE TECHNO-SAVY STUDENT. Percent x Whole = Portion; so 0.96 x Whole = 60, and Whole Amount = 60 ÷ 0.96 = 62.5 ml of medication. A SYRINGE CONTAINS 60 ML OF SALINE SOLUTION WHICH REPRESENTS 96% OF THE MEDICATION. HOW MUCH TOTAL MEDICATION WAS CONTAINED IN THE SYRINGE? 96% OF WHAT QUANTITY IS 60?

29 BSI Workshop: Mathematics AS DETERMINED BY MATHEMATICAL UNIFORMITY. If N represents the amount of total medication in the syringe, then 62.5 ml of solution. A SYRINGE CONTAINS 60 ML OF SALINE SOLUTION WHICH REPRESENTS 96% OF THE MEDICATION. HOW MUCH TOTAL MEDICATION WAS CONTAINED IN THE SYRINGE?

30 BSI Workshop: Mathematics AS DETERMINED BY THE LOGICAL VISUALISTS. The left side is divided in 96 sections; so divide the right side into 96 sections of 60/96 = 5/8 each. Now consider 100 such sections 100 x 5/8 or 62.5 ml of medication A SYRINGE CONTAINS 60 ML OF SALINE SOLUTION WHICH REPRESENTS 96% OF THE MEDICATION. 96% OF WHAT QUANTITY IS 60?

31 TECHNO-SAVY STUDENTS ARE SUCCESSFUL IF THEY HAVE NUMBER SENSE. BSI Workshop: Mathematics

32 NUMBER SENSE IS ALSO A COMMON TRAIT OF SUCCESSFUL STUDENTS WHO VALUE MATHEMATICAL UNIFORMITY.

33 LOGICAL VISUALISTS HAVE NUMBER SENSE BUT LIVE IN A WORLD FOCUSED ON AUDITORY SEQUENTIAL LEARNERS. BSI Workshop: Mathematics

34 PERCENTAGES ARE A MATTER OF SCALING AND NOT COMPARING. BSI Workshop: Mathematics A QUANTITY IS 100% OF ITSELF. STILL, WE HAVE TO RECOGNIZE DIFFERENT LEARNING STYLES.

35 ADDRESSING BASIC SKILLS AND DEMANDING ANALYSIS AND CRITICAL THINKING WHILE PROVIDING SUPPORT IS NEEDED. BSI Workshop: Mathematics there is no shortcut for “hard work.” Entrepreneurs are resourceful, but …

36 MATHEMATICAL TIME CHECK ANY REQUESTS? BSI Workshop: Mathematics

39 BSI Workshop: Mathematics Fifteen floral displays were to be created of which 12% of the flowers were red roses. Additional displays were requested. The designer wants to reduce the percentage of roses to only 7% by adding other types of flowers and redistribute the roses. How many additional flowers much be added to reduce the percentage of roses? #2 BASIC PROBLEM SOLVING W/MATHEMATICAL REASONING PERCENT PROBLEMS IN RETAIL FLORISTRY

40 BSI Workshop: Mathematics How much of a 6% solution of an alcohol and water mixture must be added to 20 ml of a 10% alcohol mixture to reduce the percentage of alcohol to 7%? #3 BASIC PROBLEM SOLVING W/MATHEMATICAL REASONING PERCENT PROBLEMS IN CHEMISTRY

41 BSI Workshop: Mathematics PROBLEM SOLVING W/MATHEMATICAL REASONING IN ART IT’S BEEN CALLED “THE GOLDEN RATIO” OR “DIVINE PROPORTION ”

What was the percent increase in height? (First find the height of the new water level by assuming that the stone is completely under water.) #7 BASIC PROBLEM SOLVING W/MATHEMATICAL REASONING PERCENT PROBLEMS IN SCIENCE, ENGINEERING, AND MATH

53 BSI Workshop: Mathematics #15 BASIC PROBLEM SOLVING W/MATHEMATICAL REASONING PERCENT PROBLEMS IN NUTRITIONAL SCIENCE Add up the percentages on the right side of the can. If the total is NOT 100%, explain why ?

54 BSI Workshop: Mathematics #16 I walked up a mountain to ask my guru, “What’s the meaning of life?” I had to trek 4 days in snow and rain, dealing with shivering nights and poor terrain. When I got to the top, he was there with the answer. To get the answer, please solve this problem. BASIC PROBLEM SOLVING W/MATHEMATICAL REASONING PERCENT PROBLEMS IN PHILOSOPHY I started up the mountain at an elevation of 65 feet and reach my teacher sitting at 10, 432 feet above sea level. If on my last day before reaching the top, I climbed 1244 feet, approximately what percent of the elevation was done on the last day?

55 MATHEMATICAL REASONING CONTINUES BUT, BYE FOR NOW, Presented by Karl Ting, Department of Mathematics March 15, 2013

56 Basil Rathbone and Nigel Bruce Peter Cushing and Nigel Stock Jeremy Brett and Edward Hardwicke Christopher Lee and Patrick MacNee Christopher Plummer and James Mason Nicol Williamson and Robert Duvall Michael Caine and Ben Kingsley Benedict Cumberbatch and Martin Freeman Robert Downey Jr. and Jude Law Jonny Lee Miller and Lucy Liu "Come, Watson, come! The game is afoot. Not a word! Into your clothes and come!“ Who are we?

57 We first see the famous phrase in the Canon in "The Adventure of the Abbey Grange" when Holmes tells Watson: "Come, Watson, come! The game is afoot. Not a word! Into your clothes and come!" The word "game" has two meanings. One is "quarry" or "spoils," and it would be the main meaning in Shakespeare's and Holmes' words. However, the other meaning of "game" is, "a diversion, pastime, or amusement; or a form of mental or physical competitive play, governed by specific rules and testing the skill, endurance, or luck of the participants."
