At least our kids should do better when up against German kids in math tests.

As long as our kids can answer the questions while hooked up to their little Wiis.

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 1950:
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 1960:
A logger exchanges a set L of lumber for a set M of money. The cardinality
of set M is 100, and each element is worth $1. Make 100 dots representing
the elements of set M. The set C of the cost of production contains 20 fewer
points than set M, and answer the following question: What is the
cardinality of the set P of profits?

TEACHING MATH IN 1970:
A logger sells a truckload of lumber for $100. Her cost of production is $80 and her profit is $20. Your assignment: Underline the number 20.

TEACHING MATH IN 1980:
By cutting down beautiful forest trees, the logger 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 MATH IN 1990:
A company outsources all of its remaining loggers. The firm saves on benefits, and when demand for its product is down, the loggers are let go. The average logger previously employed by the company earned $50,000 per year, and had 3 weeks paid vacation, a nice retirement plan and medical insurance.The contracted logger charges $50 an hour. Was outsourcing a good move for the company?

TEACHING MATH IN 1999:
A laid-off logger serving time in Folsom for blowing away several people is being trained as a COBOL 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, 01/01/2000?
