2. Teaching Math In 1960

3. Teaching Math In 1970

4. Teaching Math In 1980
A logger sells a truckload of lumber for $100. His cost of

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.)
6. Teaching Math In 2009
A logger sells a truckload of lumber for $100. His cost of production is $80 and his profit is $20. He had to pay taxes totalling $300. His payment on the lumber truck is $600 and he’s had an injunction filed against him by the Society for the Protection of the Upper Wetland Great Horny Jumping Sparrow which is costing him $2000 a day in lost revenue. What government entitlement can the logger get to save the day?
