The New, New Math..........

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. 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 1960s:...........


1. Teaching Math In 1960s (when I was in school).......

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 1970s...........

A logger sells a truckload of lumber for $100. His cost of production
is 80% of the price, or $80. What is his profit?

3. Teaching Math In 1980s.............

A logger sells a truckload of lumber for $100. His cost of production
is $80. Did he make a profit ? Yes or No?


4. Teaching Math In 1990s..........

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 2000s.............

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, and if you feel like crying, it's ok).

6. Teaching Math In 2010...........

Un hachero vende una carretada de madera para $100. El costo de la
producciones es $80. Cuanto dinero ha hecho?

ANSWER: His profit was $375,000 because his logging business is just a
front for his "other business"...............
