Teaching Math

Friends, The Time Have Changed
I received the following a few days ago from a friend. I thought it was a funny exaggeration of a real problem that we see more of every day. It reminded me of the story of someone who asked for a half dozen of chicken McNuggets at McDonald’s. The order taker told them that we don’t sell half dozens, but you can buy 6 or 9.

Last week I purchased a burger at Burger King for $2.58. The counter girl took my $3.00 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 In 1970s

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 2010

Un hachero vende una carretada de madera para $100. El costo de la producciones es $80. Cuanto dinero ha hecho?

Joke of the Day

Remember this one… an oldie.

An redneck walks into a hardware store and asks for a chain saw that will cut 6 trees in one hour. The salesman recommends the top of the line model. The redneck is suitably impressed, and buys it.

The next day he brings it back and says, "This chainsaw is defective. It would only cut down 1 tree and it took ALL DAY!"

The salesman takes the chain saw, starts it up to see what's wrong, and the redneck says, "What's that noise?"

Kids keep underestimating the importance of math. It is just sad.
