Wow, as one who started out with a double major in math and physics and consequently found advanced degrees quite easy due to the heavy math fosted upon me by that first major, I’m sooooooo glad that these education doofuses (spelled correctly?) were not around to ruin me before I learned from intelligent teachers.
Find these folks, tie them up, burn them, and launch their ashes into the sun.
Now!

I am not a math genius...I wish I were. I use Excel a lot and that plus logic gets me by. But this makes NO sense to me. How did they come up with the last step - the $10 + $10 ?? Why did they have to add up to $38 to figure out the change of 12.40?
Seems to me it’s much easier to do it the regular way - .40 to make it to 8.00 and 12.00 to get from 8.00 to 20.00
I’m reminded of the story about Gauss when his teacher thought he would keep the class busy with the problem of adding up all the numbers between 1 and 100. I’ll bet the morons that came up with Common Core would look at Gauss’s work and fail him for not demonstrating the use of the techniques which they claim are how we really do math in our heads.
These morons’ obsession with eliminating rote memorization is also completely laughable in that they insist their inefficient algorithms be memorized. I would solve their simple math problem in my head quite differently and though I will arrive at the right answer, I will be marked wrong. What then is the purpose of Common Core if not to get everyone to think exactly the same. Just a little beyond that is to get people to accept that the correct way to think must be determined by our superior educators.
Common Core is setting education back, but isn’t that what the elitists want? Dumb, compliant and accepting dolts for citizens? And are not colleges obliging them?
Nevermind...I guess I see it ....but not saying I like it. Seems like the long way around.
doofii???
