Since I know so many of my family members love the subject of mathematics, this post should brighten your day. By the way, I did NOT write this (the author is unknown).
Teaching Math in 1950: A logger sells a truckload of lumber for $100.00. His cost of production is four-fifths of the price. What is his profit?
Teaching Math in 1960: A logger sells a truckload of lumber for $100.00. His cost of production is 4/5 of the price or $80.00. What is his profit?
Teaching Math in 1970: A logger sells a truckload of lumber for $100. His cost of production is $80. Did he make a profit?
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.
Teaching Math in 1990: A selfish and inconsiderate logger cuts down a beautiful forest because he 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.)
Teaching Math in 2005: Un ranchero vende una carretera de madera para $100. El cuesto de la produccion era $80. Cuantos tortillas se puede comprar?
