Teachers can relate to this. And everyone else, should too!
Years of Math 1950 – 2010
Last week I purchased a burger at Burger King for $1.58. The counter
girl took my $ 2 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 In1970s
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, it’s ok. )
6. Teaching Math In 2009
Un hachero vende una carretada de maderapara $100. El costo de la
producciones es $80. Cuanto dinero ha hecho?
7. Teaching Math In 2013
Who cares, just steal the lumber from your rich neighbor’s property.
He won’t have a gun to stop you, and the President says it’s OK anyway
cuz it’s redistributing the wealth of those evil rich Republicans!
