I purchased a burger at Burger King for $3.58. The counter girl took my
$5. I was digging for change when I pulled eight cents from my pocket
and gave it to her. She stood there, holding the nickel and three
pennies, looking at the screen on her register. I sensed her discomfort
and tried to tell her to just give me two quarters and a dollar bill,
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? Please continue to read.
The evolution in teaching math since the 1950s:
-------------------------------------------------------
1. 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?
-------------------------------------------------------
2. 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?
-------------------------------------------------------
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
participation after answering the question: How did the birds and
squirrels feel as the logger cut down their homes? (There are no wrong
answers)
