I know that I'll never be able to use all that I learned in school. There is something to say for knowing things simply for the sake of knowing things - you know, like when you're watching Jeopardy or trying to do a crossword puzzle. I've noticed that teaching methods have changed over the years. Friend Benny Brown pointed this out to me...
1. Teaching Math In 1958:
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 1968
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 1978
A logger sells a truckload of lumber for $100.
His cost of production is $80.
Did he make a profit?
4. Teaching Math In 1988
A logger sells a truckload of lumber for $100.
His cost of production is $80 & his profit is $20.
Your assignment: Underline the number 20.
5. Teaching Math In 1998
A logger cuts down a beautiful forest because he
is selfish & inconsiderate & cares nothing for the
habitat of animals or the preservation of our wood-
lands. 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 & squirrels feel as the
logger cut down their homes? (There are no wrong
answers, & if you feel like crying, it's okay).
6. Teaching Math In 2008
Un hachero vende una carretada de maderapara $100.
El costo de la producciones es $80.
Cuanto dinero ha hecho?
Thanks, Benny
