    Years of Math 1950 - 2010

    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:

    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 In1970s

    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 2009

    Un hachero vende una carretada de maderapara $100. El costo de la producciones es $80. Cuanto dinero ha hecho?

    7. Teaching Math In 2013

    Who cares, just steal the lumber from your rich neighbor's property. He won't have a gun to stop you, and the Gubmint says it's OK anyway cuz it's redistributing the wealth.

    Came here for Oak's satire (even thought you're right), was not disappointed.

    My wife is a high school English teacher. It's not just math that's a problem. Getting kids to read more than 140 characters and write legible words is a challenge in and of itself.

    When I was in school, I never understood new math. Now, I know why. I was expected to be able to add, subtract, multiply and divide.

    Had a guy in his 40's come into work (Home Depot) the other day and ask me how to calculate the area of a square.

    I'm not kidding.

    A while back I purchased something (don’t remember what) but I gave the cashier the exact change even before he rung it up, he stood there for a few seconds then asked “How did you do that”.

    If that ain't the truth, Oak. To Msgt, it's amazing to me that people can't do simple arithmetic in their heads. I guess the old school teaching methods worked, huh? This coming from a confirmed grumpy old man.

    It's a shame that kids aren't taught the basic math skills needed to get through life...like how to count back change. It's so simple but you have to show someone how to do it before they know.

    They should teach a Basic Life Skills class in High School and make it mandatory. There's all sorts of things people need to know, but unless they're told or shown, they don't.

    A few years back my wife and I stopped at a Denney’s in Arizona. When we went to pay the check came to $9.50 and I gave the casher a ten dollar bill (before anyone screams I left the $2.00 tip on the table). The casher looked at the ten and at the check and got out her calculator to determine how much change to give back (this was before cash registers that told how much change to give).
    A month or so later we returned to the same Denney’s and had the same casher. This time I made it really hard on the poor girl. The check was $9.80 and I gave her a twenty! Out came the calculator once more! This girl was a graduate of the local High School.
    Yet another time I was in a store and I saw the cash register display, it had a picture of each coin and bill that were needed to make up my change and by each picture was the number of coins or bills needed to make change. I guess the owner gave up hope of ever finding a casher that could make change!

    I'm calling BS on this one.

    Or maybe parents could actually take part in the process of raising their own kids and make sure they're learning this stuff by going through it with them themselves.

    Might I ask why? I could not and would not make this up.

    Yeah, that would be great, assuming the kid had parents that cared enough to do it. Unfortunately, not all kids do.
