From my buddy Shannon...
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 frommy 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 2006
Un ranchero vende una carretera de madera para $100. El cuesto de la produccion era $80. Cuantos tortillas se puede comprar?

Rescue 911
On Jan 31, 2006 I flew to Tenakee (ten-a'-key) Alaska to pick up a man who had injured his leg. I had about an hour to kill while there so I cruised the village and had lunch at Rosies. Tenakee is a very cool little Alaskan village.
This is the Heli dock at Tenakee..
This is Snyder Merchantile (Since 1899) on what I guess you could call "main street" of Tenakee. Actually, it's the only street in Tenakee, and it's not quite a street either.
This is what the inside of Snider Merchantile looks like today. It's still resembles much what it must have looked like when it was built in 1899.
Main Street (Downtown Tenakee)
The light is always on at Rosies, Blue Moon Cafe.
This is the inside of the Blue Moon Cafe. No, the room is no larger looking the other way. It's just a really small, messy little joint without running water or toilets. That's right, the out house is in the back... of the resturant. Not the back yard, the back of the resturant.
