    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?

    ANSWER: His profit was $375,000 because his logging business is just a front for his marijuana farm.

    More truth than poetry in that.

    My math-specialist-public-school-teacher-husband did not laugh. Simply nodded his head (as he worked on his teach-yourself-Spanish-or-you-won't-have-a-job-next-year lessons).

    "(as he worked on his teach-yourself-Spanish-or-you-won't-have-a-job-next-year lessons)."

    I guess it wouldn't be politically correct to make the kids in an ENGLISH SPEAKING country learn English now would it?

    What a crock of crap.

    I have a friend who has been volunteering as a teacher's assistant at Franklin High School. One of his pet peeves is that he believes that contemporary methods of teaching math do not give his students the arithmetic skills that they need in the real world. His two main gripes are:

    1) Students are being allowed to use calculators at an early age, so they do not gain much experience in having to perform computations longhand, showing all of the intermediate steps needed to arrive at the answer. This, in his opinion, leads to students making the assumption that the answer "must be right" if it came from a calculator or computer, as they have not obtained enough experience working with numbers to detect gross calculation errors.

    2) Due to the use of decimal-based calculators, students are not gaining sufficient confidence with and understanding of fractions. This causes problems in shop classes, where English units are used (i.e. students cannot read tape measures and rulers quickly and accurately).

    This is no joke.

    No, not at all. That's not what I'm saying. Learning 2nd or 3rd or however many languages is a good thing IF YOU WANT TO.

    What pisses me off is that they expect us to learn "their" (take your pick of which one) language to communicate with them in an ENGLISH SPEAKING country.

    The people who LEGALLY move here should learn our language if they expect to function in society. What language they speak at home or amongst friends, etc is totally up to them.

    If you moved to Japan, would you expect them to all learn English to communicate with you?

    Alfredo, Agreed.

    Students should not be allowed to use calculators at least till High School.

    You have to know and understand the basics first.

    Like it or not, the U.S. became a bilingual country for all practical purposes in the mid-1800s when it took over half of Mexico. All schoolchildren in this country absolutely should be required to learn both English and Spanish. Knowlege of both gets more essential every year and a second language is damned hard to learn as an adult. I've struggled with it for years. In the 21st century bilingual education is not a political issue (much less a matter of "political correctness," whatever that means). It's a necessary survival tool in an economically globalized multicultural world where the U.S. can no longer even pretend to be an island unto itself.

    Regarding calculators, I agree with the sentiments expressed above.
