The Evolution of Math in the United States:

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 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 1960s...

Teaching Math In 1960

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 1970

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 1980

A logger sells a truckload of lumber for $100. His cost of production is $80.
Did he make a profit?

Teaching Math In 1990

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 2000

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 2006-2007 [sigh, 2008-2009]

Un ranchero vende una camion de madera para $100. El cuesto de la produccion era $80. Cuantos tortillas se puede comprar?

What's to understand? It's simple. It's tragic:

We muddled through to 2010: Many schools couldn't afford to stay open because not enough taxes were collected. The taxes weren't collected because companies had to cut back and close down. Companies cut back because they couldn't make enough profit. Companies couldn't make the previous year's profit because of competition from overseas. Competition came from overseas because management went overseas to make money and shelter tax profit. And because land and factories were made cheaper on this side of the ocean, foreigners moved in over here. And our Cities and Government gave them shelters to do so!! - And, then they took their money back home to where they came from to pay their families to immigrate here. And they work harder and more hours and appretiate better and...

1 - First Important Lesson - Cleaning Lady.

-- During my second month of college, our professor gave us a pop quiz.

-- I was a conscientious student and had breezed through the questions until I read the last one: "What is the first name of the woman who cleans the school?"

-- Surely this was some kind of joke. I had seen the cleaning woman several times. She was tall, dark-haired and in her 50s, but how would I know her name?

-- I handed in my paper, leaving the last question blank.

-- Just before class ended, one student asked if the last question would count towards our quiz grade?

-- "Absolutely," said the professor. "In your careers you will meet many people. All are significant. They deserve your attention and care, even if all you do is smile and say "hello."

-- I've never forgotten that lesson. I also learned that her name was Dorothy.

-- One night, at 11:30 P.M., an older African-American woman was standing on the side of an Alabama highway trying to endure a lashing rainstorm. Her car had broken down and she desperately needed a ride. Soaking wet, she decided to flag down the next car. A young white man stopped to help her, generally unheard of in those conflict-filled 1960s. The man took her to safety, helped her get assistance, and put her into a taxicab.

-- She seemed to be in a big hurry, but wrote down his address and thanked him. Seven days went by and a knock came on the man's door. To his surprise, a giant console color-TV was delivered to his home. A special note was attached..

-- In the days when an ice cream sundae cost much less, a 10-year-old boy entered a hotel coffee shop and sat at a table. A waitress put a glass of water in front of him.

-- "How much is an ice cream sundae?" he asked.

-- "Fifty cents," replied the waitress.

-- The little boy pulled his hand out of his pocket and studied the coins in it.

-- "Well, how much is a plain dish of ice cream?" he inquired.

-- By now more people were waiting for a table and the waitress was growing impatient.

-- "Thirty-five cents," she brusquely replied.

-- The little boy again counted his coins. "I'll have the plain ice cream," he said.

-- The waitress brought the ice cream, put the bill on the table and walked away.

-- The boy finished the ice cream, paid the cashier and left.

-- When the waitress came back, she began to cry as she wiped down the table. There, placed neatly beside the empty dish, were two nickels and five pennies.. You see, he couldn't have the sundae, because he had to have enough left to leave her a tip.

4 - Fourth Important Lesson. - The obstacle in Our Path.

-- In ancient times, a King had a boulder placed on a roadway. Then he hid himself and watched to see if anyone would remove the huge rock.

-- Some of the king's wealthiest merchants and courtiers came by and simply walked around it. Many loudly blamed the King for not keeping the roads clear, but none did anything about getting the stone out of the way.

-- AND IN CLOSING

I'd better mention this to you. - Now and then I'd get a call from someone who had an idea for an invention. They'd call up on the phone the IASL and leave a message. I would return their call, call them back, and the conversation always implied that I was wasting their time talking. They merely wanted to know what they should do with an idea that needed to be [quickly] taken to market.

They wanted doors to open to them. "Who do I call?" "Who do I go to?"

They implied that they didn't have time.

I got the impression that telling them anything other than what they wanted to hear, bored them. Telling them "that you just can't call someone and then tell that person your idea" - "doesn't work" - "if you expected to make money from your idea?"

It wasn't what they wanted to hear. ??

Telling them to read the website of the IASL, also wasn't what they "had time to do" or "it's far too much to do." They'd say that they had read some part of it and they'd rather call someone 'directly.'

"Who do you suggest I call?" -

-- Yeah, they didn't read it! They only said that they read it. They had a closed mind.

I would tell them to call a Patent Attorney. He or she would help them. And they'd mention that they have been to a patent attorney and it would cost them too much to get a patent. "Who can I sell my idea to? - I'll get a patent, later."

I'd tell them that "Ideas are a dime a dozen." "That you have to research your ideas, first." "I don't know how?" they'd say. "Can someone to do it for me? ..but I don't have much money to pay them," they'd quickly add.

I'd go back to telling them to come to our meetings and read our website and there the conversation would end.
