"Common Core" Math
After reading this article, I'm pretty sure it's pure nuts to teach math this way.
As the article mentions, sounds like a great way to make kids hate math. Not a good thing when math is involved so much in technology that we have to deal with more each day, and shows no sign of letting up.
I could immediately see that C was the answer. I am an engineer (pretty much have done math for a living) and that is how I do math in my head. There are lots of little tricks like that, breaking numbers up ones that are easy to work with. I taught these types of concepts to my daughter and she loves math & has never gotten less than an A through high school geometry. So no, I don't see it as stupid or turning kids off to math.

What little research I've done on Common Core, I don't care for specifically in some of the history and social studies, but that's a different story....
I attended Private Catholic Preparatory school. I am a Math wizard!
I know my denominations, my invertabrates, and common demonsterators.
Nun walks into class and asks you "What is 2 plus 2?
Kid answers 6.
Nun says "no! Try again, what is 2 plus 2?
Kid answers 9
Nuns say, No! One last chance, what is 2 plus 2?
Kid says 7.
Nun takes out her hidden ruler,, and beats the kid till his eyes bleed, then says correct answer is 4..
I will ask you again tomorrow...
That system seems to work well,, except ,, I ended up scared to death of women,,, and have a fear of hickory.
Ash and Walnut is fine,, but I wont go near Hickory..
I guess its in my Core make up
MooseGooser...Oh for the "good ole days"
Good post. Lots of teachers in my family and most ( probably all ) would agree with you 100%.

I'm of an age where flash cards were used in one room schools. Somehow, all 3 boys in my 6th grade class at Jacobus School, Butler Township became graduate engineers, one with a PHD in Geological Engineering. This was in the days of slide rules. I use a self taught form of going to the number nearest to 10 to teach people how to multiply & divide larger numbers in their head.

What I saw in the example is unnecessarily complicated - probably why computers are not in the least user friendly, IMO.
I don't remember getting straight A's in Math - but did spend a little time throwing numbers around in the building of the jets most travel on. What I found was KISS really works :).
Actually they were teaching some of that stuff already before common core. My daughter didn't really get it at first but she understood it when her old man explained it it her. Last year Liz took algebra in eighth grade. I was surprised how many in her class took it. I started looking into it and found out there is a big push for it. Now they are finding out that overall math scores are not going up because many taking it early are not getting out of it what they would otherwise after another year of prep. So I agree that it can be a problem throwing in too much complexity too early. I follow what my daughter gets in school In detail. I was a little surprised how early they start throwing algebraic concepts at kids now.
