Fifty-Seven Years of Math 1957-2014 in America: the evolution in teaching math —

1. Teaching Math In 1950’s:

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’s:

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’s:

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’s:

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’s:

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, it’s ok.)

6. Teaching Math In 2000’s:

If you have special needs or just feel you need assistance because of race, color, religion, sex, sexual orientation, age, childhood memories, criminal background, then don’t answer and the correct answer will be provided for you. There are no wrong answers.

7. Teaching Math In 2014:

Un hachero vende una carrtada de maderapara 100 pesos. El costo de la producciones es 80 pesos. Cuanto dinero ha hecho?
