Teaching math
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 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 Match in 2000:
A logger sells a truckload of lumber for $100.
His cost of production is $120, paid to a partnership owned
by his
son-in-law.
His accounting department tells him his profit is $60. This
is verified
by his auditing firm, Arthur Andersen, blessed by his
lawyers, Vinson,
Elkins, and touted by assorted Wall Street investment
bankers.
Question: How can Jesse Jackson share the spotlight on this
deal?
