This ought to make you laugh...maybe...

The Evolution in Teaching Math Since the 1950's:

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.)
