Teaching Maths
How the Job has Changed
=======================
Teaching Maths in 1950: A forester sells a lorry load of timber for
£100. His cost of production is 4/5 of the price. What is his profit?
Teaching Maths in 1960: A forester sells a lorry load of timber for
£100. His cost of production is 4/5 of the price, or £80. What is his
profit?
Teaching Maths in 1970: A forester exchanges a set "T" of timber for a
set "M" of money. The cardinality of set "M" is 100. Each element is
worth one pound. Make 100 dots representing the elements of the set "M".
The set "C", the cost of production, contains 20 fewer points than set
"M." Represent the set "C" as a subset of set "M" and answer the
following question: What is the cardinality of the set "P" for profits?
Teaching Maths in 1980: A forester sells a lorry load of timber for
£100. Her cost of production is £80 and her profit is £20. Your
assignment: Underline the number 20.
Teaching Maths in 1990: By cutting down beautiful forest trees, the
forester makes £20. What do you think of this way of making a living?
Topic for class participation after answering the question: How did the
forest birds and squirrels feel as the logger cut down the trees? There
are no wrong answers.
Teaching Maths in 1996: By laying off 40% of its foresters, 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 Maths in 1997: A company out-sources all of its foresters. The
firm saves on benefits, and when demand for its product is down, the
forester work force can easily be cut back. The average forester
employed by the company earned £20,000, had three weeks holiday, a nice
retirement plan and medical insurance. The contracted forester charges
£20 an hour. Was outsourcing a good move?
Teaching Maths in 1998: A laid-off forester with four children at home
and a ridiculous alimony from his first failed marriage comes into the
timber-company corporate offices and goes postal, mowing down 16
executives and a couple of secretaries, and gets lucky when he gets a
politician on, the premises collecting his kickback. Was outsourcing the
foresters a good move for the company?
Teaching Maths in 1999: A laid-off forester serving time in Dartmoor for
blowing away several people is being trained as a C++ programmer in
order to work on Y2K projects. What is the probability that the
automatic cell doors will open on their own as of 00:01, 01/01/00?
