Teaching Math through the ages
Because of the evolution in teaching math since the 1950s:
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 our poor little 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 this tree murderer making a living? Topic for class participation after answering the question: How did the birds and squirrels feel as the logger cut down their poor little homes? ( There are no wrong answers.)
6. Teaching Math In 2005
A climate criminal cut a beautiful branch from a tree and sold it for a 100 dollars to another climate criminal. His tree permit was 90 dollars, his carbon tax was 30 dollars, his gas was was 150 dollars, his taxes on the fuel was 80 dollars, his Unemployment Insurance tax was 20 dollars, his OHIP was 30 dollars, his road tax was 40 dollars, his truck license was 50 dollars, his Canadian Pension plan was 50 dollars and finally, his GST and PST on the entire lot was 70 dollars.
How much profit did this climate criminal make?
