For those who wonder why kids today at fast food places can't count back change then you might want to read the following history of math problems in the public schools.
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?
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?
Math in 1970
A logger sells a truckload of lumber for $100. His cost of production is $80. Does he make a profit?
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
Math in 1990
By cutting down beautiful forest trees, the logger makes $20. What do you think of this way of making a living? Topic for class participation after answering the question: How did the forest birds and squirrles feel as the logger cut down the trees? (There are no wrong answers)
Math in 2005

When our son was in the fifth grade, the school switched to "Chicago Math." It appears to have been designed to amuse college level mathematicians and confuse everyone else. Until his experience with "Chicago Math," our son was pretty good in math. After one year of it, he no longer understood the relationship between decimals, fractions, and percentages. They'd gotten him so thoroughly confused that it took several school terms to get him back on track, and he still has no confidence in his ability to do math to this day. He'll be entering high school this fall, and he still calls math the "Evil Class."
Yes,
thankfully, our president's "no child left behind" education program will put things right again!
Oh, wait...........
Heh heh heh!
Yea, it is sad.

My 9-year-old was studying long division this year, and the math textbook was so confusing, even I couldn't understand it.
They had the poor kids doing things with circles and little blocks of squares.
When I showed him how I was taught to do long division, he said, "How come it's so much easier your way, Mommy?"
Good question, kid. Good question.
Regards,
PS: Back a couple of years ago, he got the following:
Find the sum: 7+8=_____
How did you arrive at this answer?
(When my son asked me what that meant, I told him I honestly didn't know. Turns out they want the kids to say, "doubles plus one." Silly me, and I thought that just knowing that 7+8=15 was all you needed to know.)
Chicago Math:
On Election Day, the democrat candidate is trailing the republican by 100,000 votes, with 50,000 ballots still to be counted. From this, we can surmise that:
a. The republican will win by at least 50,000 votes.
b. The republican will win by fewer than 50,000 votes.
c. The republican will win, but the final margin is not
determinable as yet.
d. The democrat will win.
If you chose A or B or C you are a naive fool.
The correct answer, of course, is D.
I teach mathematics to inner-city postsecondary school students. Almost none of them understand simple fractions. Almost none of them understand how to place the decimal point when converting from decimals to percentages.
Those who do not know these things do not seem capable of learning them.
One of them, when asked to calculate a 15% tip on a $15.00 restaurant bill, came up with $137.50.

It looks like another generation of American school kids is about to get screwed out of an education.
Just when you think it can't get any worse...
I teach mathematics
doesn't look like it ...
