This came from a newsgroup I frequent. I rather enjoyed it and thought you might as well.
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 out 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 give me 2 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 1950's
1. Teaching math in 1950:
A logger sells a truck load of lumber for $100. His cost of production is
4/5 of the price. What is his profit?
2. Teaching math in 1960
A logger sells a truck load of lumber for $100. His cost of production is
4/5 of the price, or $80. What is his profit?
3. Teaching Math in 1970
A logger sells a truckload of lumber for $100. His cost of production is
$80. Did he make a profit?
4. 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.
5. 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
discussion after answering the question: How did the birds and squirrels
feel as the logger cut down their homes? Remember: THERE ARE NO WRONG
ANSWERS.
