Teaching Math: A Historic Overview Teaching Math in 1950: A logger sells a truckload of lumber for $100. His cost 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 exchanges set “L” of lumber for a set “M” of money. The cardinality of set “M” is 100. Each element is worth one dollar. The set “C,” the cost of production contains 20 fewer points than set “P.” What is the cardinality of the set “P” of profits?

Teaching Math in 1990: By cutting down beautiful forest trees, the logger makes $20.

What do you think about the way he makes a living? Topic for class participation after answering the question: How did the forest birds and squirrels feel as the loggers cut down the trees? There are no wrong answers.

Teaching Math in 1996: By laying off 402 of its loggers, a company improves its stock price from $80 to $100. How much capital gain per share does the CEO make by exercising his stock options at $80. Assume capital gains are no longer taxed, because this encourages investment.

Teaching Math in 1997: A company outsources all of its loggers. They save on benefits and when demand for their product is down the logging work force can easily be cut back. The average logger employed by the company earned $50,000, had 3 weeks’ vacation, received a nice retirement plan and medical insurance. The contracted logger charges $50 an hour. Was outsourcing a good move?

Teaching Math in 1998: A logging company exports its wood-finishing jobs to its Indonesian subsidiary and lays off the corresponding half of its US workers (the high paid half). It clear-cuts 95% of the forest, leaving the rest for the spotted owl, and lays off all its remaining US workers.

It tells the workers that the spotted owl is responsible for the absence of fellable trees and lobbies Congress for an exemption from the Endangered Species Act. Congress instead exempts the company from all federal regulation. What was the return on investment of the lobbying? Teaching Math in 2000: A logger sells a truckload of lumber for $100. His cost of production is $120. How does the logger determine that his profit margin is $60?
