One of my teachers handed this out last semester and I thought that it was pretty funny:
Math for 2005
Last week I purchased a burger at Burger King for $3.58. The counter girl took my $4.00 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 a 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 1955:
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 1965:
A logger sells a truckload of lumber for $100. His cost of production is 4/5 of the price, of $80. What is his profit?
Teaching Math in 1975:
A logger sells a truckload of lumber for $100. His cost of production is $80. Did he make a profit?
Teaching Math in 1985:
A logger sells a truckload of lumber for $100. His cost of production is $80 and his profit is $20. Your assignment: Underling the number 20.
Teaching Math in 1995:
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 maderero vende un camion de madera de construccion para $100. El coste de produccion es $80. Cuantas tortillas puede el comprar?
