Years of Math 1950 - 2014 Last week I purchased a burger at Burger King for $2.58. The counter girl took my $ 3 and I was digging for my change when I pulled 8 cents from my pocket and gave it to her. She stood there, holding the nickel and 3 pennies, while looking at the screen on her register. I sensed her discomfort and tried to tell her to just give me two quarters , but she hailed the manager for help. While he tried to explain the transaction to her, she stood there and cried. 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 In 1970s 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, its ok. ) 6. Teaching Math In 2000 Un hachero vende una carretada de maderapara $100. El costo de la producciones es $80. Cuanto dinero ha hecho? 7. Teaching Math In 2014 Who cares, just steal the lumber from your rich neighbors property. He wont have a gun to stop you, and anyway its a redistribution of wealth.
