The history of math

1960’s Arithmetic test:
“A logger cuts and sells a truck load of lumber for $100. His cost of production is four-fiths of that amount.
What is his profit?”
70’s New Math test:
“A logger exchanges a set (L) of lumber for a set (M) of money. The cardinality of set M is 100. The set C of production costs contains 20 fewer points.
What is the cardinality of set P of profits?”
80’s education reform version:
“A logger cuts and sells a truckload of lumber for $100. His cost is $80, and his profit is $20.
Find and circle the number 20.”
90’s version:
“An unenlightened logger cuts down a beautiful stand of 100 old growth trees in order to make a $20 profit.
Write an essay explaining how you feel about this as a way of making money.
Topic for discussion: How did the forest birds and squirrels feel?”
