Years  of Math 1959 - 2010

Last  week I purchased a burger at Burger King for $1.58. The  counter girl took my $ 2 and I was digging for my change when  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:
 
1.  Teaching Math In 1950s
A  logger sells a truckload of lumber for $100. His cost of  production is 4/5 of the price. What is his profit  ?
 
2.  Teaching Math In 1960s
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?
 
3.  Teaching Math In 1970s
A  logger sells a truckload of lumber for $100. His cost of  production is $80. Did he make a  profit?
 
4.  Teaching Math In 1980s
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.
 
5.  Teaching Math In 1990s
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, and if you  feel like crying, it's ok. )
 
6.  Teaching Math In 2009
Un  hachero vende una carretada de maderapara $100. El costo de la  producciones es $80. Cuanto dinero ha  hecho?

 Year  2010:
Who  cares, just steal the lumber from your rich neighbor's  Property, he won't have a gun to stop you, and they  says its OK anyway cuz its redistributing the  wealth
