Thinking Skins Posted October 30, 2005 Share Posted October 30, 2005 This is an email I got. I found it funny, and its definately related to another thread on the board. Its very related to the real world because I remember about a month ago, I bought a bottle of OJ and some candy for about $2.50. When I paid with a $100 bill, the girl froze for a minute, then proceeded to give me back $120 change. Now would I have been wrong if I took the money? I didn't, but it just highlites this message even more. Evolution of the teaching of math Last week I purchased a burger and fries at McDonalds for $3.58. The counter girl took my $4.00 and I pulled 8 cents from my pocket and gave it to her. She stood there, holding the nickel and 3 pennies. While looking at the screen on her register, I sensed her discomfort and tried to tell her to just give me two quarters, but she hailed the manager for help. While he tried to explain the transaction to her, she stood there and cried. _____ Why do I tell you this? Because of the evolution in teaching math since the 1950s: Teaching Math In 1950 A logger sells a truckload of lumber for $100. His cost of production is 4/5 of the price. What is his profit? Teaching Math In 1960 A logger sells a truckload of lumber for $100. His cost of production is 4/5 of the price, or $80. What is his profit? Teaching Math In 1970 A logger sells a truckload of lumber for $100. His cost of production is $80. Did he make a profit? Teaching Math In 1980 A logger sells a truckload of lumber for $100. His cost of production is $80 and his profit is $20 Your assignment: Underline the number 20. Teaching Math In 1990 A logger cuts down a beautiful forest because he is selfish and inconsiderate and cares nothing for the habitat of animals or the preservation of our woodlands. He does this so he can make a profit of $20. What do you think of this way of making a living? Topic for class participation after answering the question: How did the birds and squirrels feel as the logger cut down their homes? (There are no wrong answers.) Teaching Math In 2005 Un ranchero vende una carretera de madera para $100. El cuesto de la produccion era $80. Cuantos tortillas se pu ede comprar?

DeanCollins Posted October 31, 2005 Share Posted October 31, 2005 this reminds me of my favorite buss. joke. Two brothers go into the produce buss. The buy the fruit for a $1 and sell the fruit for a $1. At the end of the first year, the younger brother says to the older "we're not making any money" the older brother " don't worry, next year we'll get a bigger truck" Link to comment Share on other sites More sharing options...
