picked this up on another BB :
Evolution of Math in California
Last week when purchasing 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 she could 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 in California 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?
Remember, there are no wrong answers.
