The evolution of math in America...

(Thanks goes to my cousin, Steve (once again) for providing this lesson in math via an e-mail...LOL!!!  Good stuff!)

------------------------------------------------

Last week I purchased a burger at a fast food restaurant 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 In1970s

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. )

Un hachero vende una carretada de maderapara $100. El costo de la
producciones es $80. Cuanto
dinero ha hecho?

Who cares, just steal the lumber from your rich neighbor's property. He
won't have a gun to stop you, and it's OK anyway cuz it's redistributing
the wealth.
