Evolution of Math Instruction
Last week I purchased a burger and fries at McDonalds for $3.58.
The counter girl took my $4.00 and 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.& nbsp;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 truck load 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.)

Un ranchero vende una carretera de madera para $100.
El cuesto de la produccion era $80. Cuantos tortillas
se puede comprar?

I think that post and your signature are quite hilarious. I grew up in the public school system, and thankfully got in some good years in Florida before moving to the school I attended in Dothan. It wasn't exactly the best when it came to curriculum and staff (not to say that all Alabama schools are that way, just some of them).
@Drnaline,
Well that's what happens when you hire foreigners.

Just where did that come from?
@Drnaline,
He must be native american. No ships were needed, they walked. If he's not native to this land then he might want to explain his bias, not being a foriegner and all?
@Drnaline,
Lol! that is really funny!
