The harder I work, the luckier I get. â€•Samuel Goldwyn
I havenâ€™t lost my mind. Half of it just wandered off, and the other half went looking for it.
Math instruction through the ages
June 26, 2013Teaching math in 1963:
A logger sells a truckload of lumber for $100. HisÂ cost of production is 4/5 of the selling price. What is hisÂ profit?
Teaching math in 1973:
A logger sells a truckload of lumber for $100. His costÂ of production is 4/5 of the selling price, or $80. What is hisÂ profit?
Teaching math in 1983:
A logger sells a truckload of lumber for $100. HisÂ cost of production is $80. Did he make a profit?
Teaching math in 1993:
A logger sells a truckload of lumber for $100. HisÂ cost of production is $80 and his profit is $20. YourÂ assignment: Underline the number 20.
Teaching math in 2003:
A logger cuts down a beautiful forest because he isÂ selfish and greedy and cares nothing for theÂ habitat of animals or the preservation of the environment. He does this so he can make a profit ofÂ $20. What do you think of this way of making a living? And how do you think the birds and squirrels felt as theÂ logger cut down their homes? (There are no wrongÂ answers, and if you feel like crying, itâ€™s okay.)
