Math Through the Ages--
Teaching Math in 1950: 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 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 for $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 greedy logger makes $20. What do
you think of this way of making a living? Topic for
class participation and role play 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 Andersen determine that his profit margin
is $60 ?
