Fifty Years of Math 1957 - 2007
Last week I purchased 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. Why do I tell you this?
Because of the evolution in teaching math since the 1950s:
1. Teaching Math In 1950s
A logger sells a truckload of lumber for $100. His cost of production
is 4/5 of the price. What is his profit ?

5. Teaching Math In 1990s
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 o f
$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, and if you feel like crying, it's ok. )
