I didn’t write this, but I thought it was funny…
Teaching Math in1950:
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 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 a set L of lumber for a set M of money. The cardinality
of set M is 100. Each element is worth one dollar. Make 100 dots
representing the elements of the set M. The set C, the cost of production,
contains 20 fewer points than the 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 of profits?
Teaching Math in 1980:
A logger sells a truckload of lumber of $100. His cost of production is
$80 and his profit is $20. Your assignment: underline the number 20.
Teaching Math in 1990:
By cutting down beautiful forest trees, the logger makes $20. What do you
think of this way of making a living? What’s wrong about it? 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 2000:
A logger sells a truckload of lumber for $100. His cost of production is
$120. How does Arthur Anderson determine that his profit margin is $60.
And, how many documents were shredded to achieve this number?
Teaching Math in 2010:
El Loggero se habla with the truckero y se ponen de acuerdo con otro driver
de la conpentencia y etc….
