The Evolution of Math

Well, I don't normally do this, but it is too TRUE to pass up (from a teacher's perspective). I was surfing some blogs, and found this interesting post. I will not tell you the source, as the title of this blog is offensive. But this post is excellent. Read on....

Subject: Evolution 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 centsfrom 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 thehabitat 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 thequestion: 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 por $100.El cuesto de la produccion es $80. Cuantas tortillas se puede comprar?

I’d say mucho tortillas but it depends where you go.

Another blurb I read back in the seventies that stuck with me out of a Fat Freddie and Free Wheelin’ Franklin comic. It was in a side panel to a Fat Freddie’s Cat adventure.

Man reading paper at lunch counter: Sez here that 75% of all Americans lack basic math skills.Man on next stool: No kidding? Is that a lot?
