Fifty Years of Math

1958 – 2008


Last week I purchased a burger at Burger King 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 1950’s:

1. Teaching Math In 1950’s

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 1960’s

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 In 1970’s

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

4. Teaching Math In 1980’s

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 1990’s

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. )

6. Teaching Math In 2008

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

My wife says I was "born old." Well, maybe. After a rough-in-places life, I've reached the point I think I can expound from time to time. So I will. Born in St. Louis, raised in Decatur Ga. Married disasterously, divorced, married to #2 - successfully now for 30 years. Converted to Orthodox Christianity - member of the Russian Orthodox Church Outside of Russia. May post something about that later. Children - 3 - not bio, but they are mine and I love 'em. Grandkids - 10 or 11 or 12 or something. Only 1 girl among 'em. Need more girls, but the kids are "through" reproducing. Hobbies - woodworking, woodturning. Like to listen to classical music. Politically EXTREMELY conservative in the true sense of the word. I seem to say "Harumph" a lot more than I used to...
