The evolution of teaching Math

Postby Paul » Wed Jul 01, 2009 9:29 am

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?

So what's the answer? :)
There were hard lines out there if you wanted them, and easy ones if you didn't. (Right Max )

Twenty what, pink elephants?
Just because you're talking about money doesn't mean everyone will know the answer without a label.

See me after class.
