The future of math

Years of Math 1950 - 2010  

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. 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 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 ?

2. Teaching Math In 1960s
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 1970s
A logger sells a truckload of lumber for $100. His cost of production is $80. Did he
make a profit?

4. Teaching Math In 1980s
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 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 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 2009
Un hachero vende una carretada de maderapara $100. El costo de la producciones es
$80. Cuanto dinero ha hecho?
