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:

Teaching Math In 1950

A logger sells a truckload of lumber for $100. His cost of

production is 4/5 of the price.

What is his profit?

Teaching Math In 1960

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?

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 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.)

Teaching Math In 2005

Un hachero vende una carretada de madera para $100. El costo de la

producci?n es $80...

This may be old, but it seems to be more true each day as we go.
