1952 (Teaching Basic Math): A logger sells a truckload of lumber for $100. His cost of production is 4/5 of this price. What is his profit? 1962 (Teaching Traditional Math): A logger sells a truckload of lumber for $100. His cost of production is 4/5 of this price, or in other words, $80. What is his profit? 1972 (Teaching New Math): A logger exchanges a set L of lumber for a set M of money. The cardinality of set M is 100 and each element is worth a dollar. Make a square array of 100 dots to represent the elements of set M. The set C of the cost of production contains 20 fewer elements than set M. Represent the set C as a subset of set K and answer the following question: What is the cardinality of set P of profits? 1982 (Teaching Math for Esteem Learning): A logger sells a truckload of lumber for $100. His cost of production is $80 and his profit is $20. Your assignment is to underline the number 20. 1992 (Teaching Outcomes-based De-streamed Integrated Math): By cutting down beautiful forest trees, an environmentally ignorant logger makes a profit of $20. What do you think of this way of making a living? In your group, use role-play to determine how the forest birds and squirrels feel. There are no wrong answers. 2000 (Teaching Reality Math): A company out-sources all of its loggers. The firm saves on benefits, and when demand for its product is down, the logging work force can easily be cut back. The average logger employed by the company earned $50,000, had three weeks vacation, a nice retirement plan and medical insurance. The contracted logger charges $50 an hour. Was outsourcing a good move? 2002 (Teaching Enhanced Reality
Math): By laying off 40% of its loggers, a company improves its
stock price from $80 to $100. How
much capital gain per share does the CEO make by exercising his stock
options at $80? Assume capital gains are no longer taxed, because this
encourages investment. |
