Welcome to Gaia! ::

A mom and dad were worried about their son not wanting to learn math at the school he was in, so they decided to send him to a Catholic school. After the first day of school, their son comes racing into the house, goes straight into his room and slams the door shut. Mom and dad are a little worried about this and go to his room to see if he is okay. They find him sitting at his desk doing his homework. The boy keeps doing that for the rest of the year. At the end of the year the son brings home his report card and gives it to his mom and dad. Looking at it they see under math an A+.

Mom and dad are very happy and ask the son, "What changed your mind about learning math?"

The son looked at mom and dad and said, "Well, on the first day when I walked into the classroom, I saw a guy nailed to the plus sign at the back of the room behind the teacher's desk and I knew they meant business."

Teacher: If I give you two rabbits and two rabbits and another two rabbits, how many rabbits have you got?
Student: Seven!

Teacher: No, listen carefully again. If I give you two rabbits and two rabbits and another two rabbits, how many rabbits have you got?
Student: Seven!

Teacher: Let's try this another way. If I give you two apples and two apples and another two apples, how many apples have you got?
Student: Six.

Teacher: Good. Now if I give you two rabbits and two rabbits and another two rabbits, how many rabbits have you got?
Student: Seven!

Teacher: How on earth do you work out that three lots of two rabbits is seven?
Student: I've already got one rabbit at home now!

The Evolution of a Math Problem

1950:
A lumberjack sells a truckload of lumber for $100. His cost of production is 4/5 of this price. What is his profit?

1960 (traditional math):
A lumberjack sells a truckload of lumber for $100. His cost of production is 4/5 of this price, or in other words $80. What is his profit?

1970 (new math):
A lumberjack exchanges a set L of lumber for a set M of money. The cardinality of set M is 100, and each element is worth $1. Make 100 dots representing the elements of set M. The set C is a subset of set M, of cardinality 80. What is the cardinality of the set P of profits, if P is the difference set MC?

1980 (equal opportunity math):
A lumberjack sells a truckload of wood for $100. His or her cost of production is $80, and his or her profit is $20. Your assignment: Underline the number 20.

1990 (outcome based education):
By cutting down beautiful forest trees, a lumberperson makes $20. What do you think of his way of making a living? In your group, discuss how the forest birds and squirrels feel, and write an essay about it.

1995 (entrepreneurial math):
By laying off 402 of its lumberjacks, a company improves its stock price from $80 to $100. How much capital gain per share does the CEO make by exercising his stock options at $80? Assume capital gains are no longer taxed, because this encourages investment.

1998 (motivational math):
A logging company exports its wood-finishing jobs to its Indonesian subsidiary and lays off the corresponding half of its US workers (the higher-paid half). It clear-cuts 95% of the forest, leaving the rest for the spotted owl, and lays off all its remaining US workers. It tells the workers that the spotted owl is responsible for the absence of fellable trees and lobbies Congress for exemption from the Endangered Species Act. Congress instead exempts the company from all federal regulation. What is the return on investment of the lobbying?
