Teaching Math 

So sad and yet so true.  Thanks Mike for the laugh. 

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 In1970s

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. )

Who cares, just steal the lumber from your rich neighbor’s property. He
won’t have a gun to stop you, and the President says it’s OK anyway cuz it’s
redistributing the wealth.

In Liberty,
