New Teaching Math through the decades

Last week a I purchased something for $1.58. I handed the cashier $2.00
and started digging for some change. I pulled out 8 cents and gave it
to her. She stood there with $2 and 8 cents. She looked bewildered,
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 burst into tears. The incident got
me thinking about how our kids were learning math in school (or not).

Teaching Math In 1950: A logger sells a truckload of lumber for $100.
His cost of production is 4/5ths of the price. What is his profit?

Teaching Math In 1970: A logger exchanges a set "L" of lumber for a set
of "M" of money. The cardinality of set "M" is 100. Each element is
worth one dollar. Make 100 dots representing the elements of the set
"M." The set "C," the cost of product ion, contains 20 fewer points
than set "M."
Represent the set "C" as a subset of set "M." Answer this question:
What is the cardinality of the set "P" of profits?

Teaching 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 squirrels feel as the logger cut down the trees.
(There are no wrong answers)

Teaching Math In 2000: A logger sells a truckload of lumber for $100.
His cost of production is $120. How does Arthur Anderson determine that
his profit margin is $60?

Teaching Math in 2020: El hachero vende un camion carga por $100. La
cuesta de production es ...

Teaching math in 2018: 2+2=4 (all answers already given, in order for all children to get the same grade so as to not hurt anyone's feelings or separate them into groups by level of intelligence)

 

Teaching math in 2100: insert microchip into external cranium port and activate.

Shit ... that ain't nothin'  My nephew is doing something inside the DC beltway and the FBI a while back actually spend a rather pleasant 30 minutes on the phone with Uncle Henry.  Some sort of security check.  Forget 2100.  How about the year 2025 and if man is still alive he will just think that magic thought and activate that big chip INSIDE his head.  Thought wear.  The sum of all man kinds knowledge instantly available.  Yikes!  HB of CJ (old coot)

I got that beat. A few years ago in a business meeting I was asked the price of each unit and I said "seventeen hundred". There was silence in the air. I looked up and the other folks in the meeting, including two gals with doctoral degrees, we're just looking at me. Finally one asked me "what number is that?". I just looked back at them and slowly said "one thousand and seven hundred dollars". They then responded with "why didn't you just say that?".

Some kids don't like math.

 

I hated it.

 

Then again, I had some crappy math teachers.

 

Me too! And it was in the 70's and exactly like that example.

 

GUYS,

  EXACTLY WHY I CHUCKED IT AFTER THE 9TH GRADE IN '67............

 

   FUCK 'EM!

Around here its:

"You want fries wit dat?"

 

I was at Wendy's just the other day and my meal came to $5.49. I handed the cashier a ten dollar bill and then pulled out two quarters and I thought her head was going to explode. I decided to rescue her and said my change is 5 dollars and a penny. She let out a huge sigh of relief and said, I am not a math person. Really? This is what, 2nd grade-level math?
