The Evolution of Teaching Math
Last week when purchasing a Burger at Burger King for
$1.58. The counter girl took my $2 and I was digging for my change when
I pulled 8 cents from my pocket and gave it to her. She stood there,
holding the nickel and 3 pennies, while looking at the screen on her register. I
sensed her discomfort and tried to tell her to just give me two quarters,
but she hailed the manager for help. While he tried to explain the
transaction to her, she stood there and cried.
Why do I tell you this? Because of the evolution in
teaching math since the 1950s:
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 sells a truckload of lumber for $100. His cost
of production is $80. Did he make a profit?
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
A logger cuts down a beautiful forest because he is
selfish and inconsiderate and cares nothing for the habitat of animals or the
preservation of our woodlands. He does this so he can make a profit of
$20. What do you think of this way of making a living? Topic for class
participation after answering the question: How did the birds and
squirrels
feel as the logger cut down their homes? (There are no wrong answers.)
Teaching Math In 2005
