Math In Disney World! By: Tabitha Edwards I Love Math! I love math so much because math is always all around you. ItвЂ™s even around you when you are at Disney World! The PlanвЂ¦ My Mom, Mike, my friend Ashley and I all planned to go to Disney World together and have so much fun! But before we went we had to plan out our tripвЂ¦ We would have 4 days to plan for. So we came up with a planвЂ¦ The DetailsвЂ¦ We decided that we were going to take: 1 day to get to Disney World 1 day to spend in Disney World and have a blast! 2 days to go shopping for stuff to remember the trip. So how do you think you could show a comparison between what we do with the day(s) to how many days there are total? Could Fractions Work? Do you think fractions would work for showing this relationship between the days? If you think yesвЂ¦ you would be right! Keep in mind that the numerator is the number (or day in this case) that we are using for something, and the denominator is the number (amount of days) that we have to work with, the total. пЃ¬ So letвЂ™s see how showing our days as fractions would look like. пЃ¬ Beginning of Fractions пЃ¬ 1 day out of a total of 4 days is going to be spent in getting to Disney World: 1 day getting to Disney World пѓ Numerator (what we use) 4 days total we have пѓ Denominator (what we have total) пЃ¬ 1 day out of a total of 4 days is going to be spent in Disney World: 1 day in Disney World пѓ Numerator 4 days total we have пѓ Denominator Beginning of Fractions Continued 2 days out of a total of 4 days is going to be spent shopping: 2 days of shopping пѓ Numerator 4 days total we have пѓ Denominator This is how I think about the days and how we are going to use them. In terms of fractions we are using 2 out of our 4 days we have available to shop. This is what a fraction means. SoвЂ¦ So now that we figured out what a fraction means and how we could use it. пЃ¬ Off to Disney World Mom, Mike, Ashley, and I go! пЃ¬ Math is Everywhere in Disney World! I first found that out when I saw CinderellaвЂ™s Castle. Then I began to wonderвЂ¦ How many towers it took to make the castle? I countedвЂ¦ Twelve Towers! I found 12 towers. But one out of the twelve towers is much taller than the rest. What portion is the tallest tower to the rest of the towers? Is there a way you can show or explain the comparison to me? Fractions! The fact that 1 out of a total of 12 towers is taller than the rest than that means 1 out of 12 towers is the tallest. If you thought that the best way to show this explanation is 1/12th then you were right! A Visit to Minnie Mouse After I visited the castle I went to visit Minnie Mouse! I asked Minnie how many whole white polka dots are on your dress? Minnie told me that in 1/4th of her dress there are 15 whole white polka dots. Confusion I didnвЂ™t quite understand what Minnie meant by that so I tried to think of the problem in another wayвЂ¦ Вј has 15 whole white polka dots. LetвЂ™s think about this. пЃ¬ 1 out of 4 sections of her dress has exactly 15 whole white polka dots. пЃ¬ So how could we solve the problem? пЃ¬ http://www.dressaday.com/081306_OrangePolkaDotDress4.jpg LetвЂ™s solve the problem! So after thinking about the problem, I began to figure out how many polka dots are on her dress altogether knowing that there are 15 dots in 1 out of 4 sections of her dress. How would you figure this problem out? вЂў There are 15 whole white polka dots in Вј of Minnie MouseвЂ™s dress. How many of these dots are there in all on her dress? You couldвЂ¦ *You know there are 15 dots in every Вј or a quarter section of her dress. And it takes 4 sections of her dress to make it whole- 4/4= 1 whole dress. Вј+Вј +Вј + Вј= 4/4 (1 whole dress) 15+15+ 15+ 15= 60 whole white polka dots 60 Whole White Polka Dots! HereвЂ™s How You Do it! Off to Sherwood Forest! After I said bye to Minnie I went to see Friar Tuck and Robin Hood to show them the new Mickey Mouse ears I had earned from Mickey. ThatвЂ™s a lot of ears! When my mom took the picture she said that there are 8 sets (or pairs) of ears including my own personal pair and my new Mickey ears. вЂў Then she asked me how many brown ears are there out of the 8 ears she counted? How Many Brown Ears Did You Find? When I looked at the picture I saw that Friar Tuck, Robin Hood, and I (my personal pair that I already had) all had brown ears. The only ears that werenвЂ™t brown were my black Mickey Mouse ears. What to do? SoвЂ¦ what can you do to show these relationships between our ears? How would you show how many brown ears there are all together out of the total 8 ears that there originally are? How would you show how many black ears out of the total 8 ears there are? You couldвЂ¦ Could we use fractions to show the relationship? Yes! How would we use fractions? You couldвЂ¦ Friar Tuck+ Robin Hood+ Me= Brown Ears 2/8 + 2/8 + 2/8= 6/8= Вѕ (we all have 2 ears each, add them together and there are 6 out of 8 brown ears all together). And Вѕ is the same as 6/8 it is just shown in a different way. It is an equivalent fraction! Brown Ears пЃ¬ SeeвЂ¦ Me, Robin Hood, and Friar Tuck all have 2 brown ears each which adds up to a total of 6 brown ears out of 8 brown ears 6/8th. But you can reduce it to Вѕ . How can you do this? Well there are 4 pairs of ears, and 3 out of the 4 pairs are brown. So Вѕ are brown. Brown ears vs. Black ears So since there are a total of 6/8th or 3 out of 4 pairs of brown ears in our pictureвЂ¦ how many black ears are there? Black Ears вЂў We couldвЂ¦ 2 out of the 8 ears are black, so 2/8th are black ears or we could also say that 1 pair out of the 4 total pairs of ears are black ears or Вј . ThatвЂ™s how many black ears there are! Souvenir time! After saying bye to Friar Tuck and Robin Hood, we all went to a Disney shop to buy a souvenir. Mom gave me $28 and told me that I could spend Вѕ of it but the other Вј had to be put away into my savings jar. вЂў So I thought to myself, what is Вѕ of $28? What do you think it is? How would you figure it out? You couldвЂ¦ So I have $28 and I can spend only Вѕ of it. So if I separate the $28 into separate and equal groups of 4 dollars it will be easier for me to figure out how much of the 28 dollars I can spend. I end up with 7 equal groups of 4 dollars. Now if I take 3 of the 4 dollars out of every equal group of 4 I will know how much I can spend. After counting up together how many dollars I took out of the 7 groups of 4 dollars I come up with 21 dollars. So I can spend $21 on a souvenir, that is Вѕ of my original $28. Here is a visual way of doing the problem. Donald or Tigger? So now that I know how much I can spend I went to go and pick out a souvenir. When I got there I had to choose between a plush Donald Duck or a plush Tigger. Donald costs $15.75 and Tigger costs $18.20. http://www.embroiderymaster.com/W ebsite_Images/Baby/TiggerPlush3.jpg A DilemmaвЂ¦ So here is the dilemma, based on how much Donald and Tigger cost and how much money I have I want to keep as much change as possible. вЂў Which purchase will leave me with more change? What will the change difference be between what Donald costs and what Tigger costs? You couldвЂ¦ $21 is how much I can spend. Donald costs $15.75. Tigger costs $18.20. Which is better and what is the difference? $21.00 $21.00 $05.25 -$15.75 -$18.20 -$02.80 $05.25 $02.80 $02.45 Change with Change with The Difference Donald Tigger And the winner isвЂ¦ So since I am able to have $5.25 as change with buying Donald Duck. Drum roll pleaseвЂ¦ I choose Donald Duck. But donвЂ™t worry Tigger, I will buy you next time. All Good Things Must Come to an End. Well we visited CinderellaвЂ™s Castle. We talked fashion with a sweet Minnie Mouse. We counted ears with Friar Tuck and Robin Hood. And we compared prices with Donald and Tigger. Boy I had a great time, did you? I hope you did.
