I didn’t write this, but I thought it was funny…

**Teaching Math in1950:**

A logger sells a truckload of lumber for $100. His cost of production is

4/5 of the price. What is his profit?

**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?

**Teaching Math in 1970:**

A logger exchanges a set L of lumber for a set M of money. The cardinality

of set M is 100. Each element is worth one dollar. Make 100 dots

representing the elements of the set M. The set C, the cost of production,

contains 20 fewer points than the set M Represent the set C as a subset of

set M and answer the following question: What is the cardinality of the set

P of profits?

**Teaching Math in 1980:**

A logger sells a truckload of lumber of $100. His cost of production is

$80 and his profit is $20. Your assignment: underline the number 20.

**Teaching Math in 1990:**

By cutting down beautiful forest trees, the logger makes $20. What do you

think of this way of making a living? What’s wrong about it? Topic for

class participation after answering the question: How did the forest birds

and squirrels feel as the logger cut down the trees? (There are no wrong

answers).

**Teaching Math in 2000:**

A logger sells a truckload of lumber for $100. His cost of production is

$120. How does Arthur Anderson determine that his profit margin is $60.

And, how many documents were shredded to achieve this number?

**Teaching Math in 2010:**

El Loggero se habla with the truckero y se ponen de acuerdo con otro driver

de la conpentencia y etc….
