THANK you! I was gonna do that, and you did it for me. us.

How to use Common Core to zip up...

Yes! And in the winter*, I can only count to 10.

and the current version of the "New Math" cultists still think that AS is fiction...

Sad.

It's late...please explain how history is being taught out of sequence? I still have content standards to teach and the Common Core is just but one tool in the kit of strategies to read and think like a historian.
For the first time ever...I've been freed from the inch deep-mile wide approach to world history. I just finished a month long unit to start the year on the Age of Reason (Enlightenment) to establish the grounds for democratic thinking and change around the world. For the first time ever, I've had the time at my discretion to utilize important primary source documents versus the shittiest textbook on earth, for the students to read and write about. I finally have kids understanding Locke's concept of life, liberty and property. I even had one kid after we read the Declaration of Independence try to convince me that John Locke wrote it and not Jefferson.
I have kids that can now understand the differences in Hobbes view of the Social Contract with Rousseau's collectivist view of the Social Contract. For me being a history teacher...I can now teach history.

As for the math teachers down the hall...well they are tearing the hair from their heads trying to figure this shit out.

Good job as parents, too! :-)

I disagree with the math question and agree with the kid's response. You can't always take only 2 from 5 and add it. Suppose you have one circuit pulling 5mA and another pulling 8mA. Your power budget only allows 10mA. You cannot simply subtract current you wish you weren't pulling.

Based on all of the politicization of Common Core, I suspect this wrongheaded question has almost nothing whatsoever to do with Common Core.

...18, 19, 20, infinity:-)

Maybe I will look again - and start in the middle this time. I am not attracted to someone spending a lot of time telling me about the process rather than the data.

You want the supporting data? Here they are.

As far as Dr. Pesta's talk is concerned, you missed the most frightening parts when he starts talking with proof about the mind bending stuff with CC sex education

Our 14 year old also said use base 13. There's still hope for the next generation.

Yes...that's the goal. :(

When I was a kid, back in the stone age, I got every bit as inane comments from teachers of English and Social Studies. Example (grade 11) Q: Explain socialism. My answer was something like "It's where the government owns everything and everyone works for the government." Not too bad for a 16 year old. Teacher's answer: "It's where the top and bottom of the income ladder is cut off." I didn't know how to respond at that age, with my limited knowledge. All I knew at the time was that it didn't seem right. I could go on and on with examples from my sons and grandchildren's experiences. Giving my grandson some books, he asked me after reading them, "How can they get away teaching that stuff?" My response -- "Because we let them."

Given the logic employed in the "answer" there are an infinite number of answers. I doubt that the "teacher" is aware of that or much else for that matter.

The assault against reason is subtle. Since when is achieving 10 by adding 8 and 5 not wrong? I could understand regrouping the values in (8+5) so that one of them is 10 is possible, i.e., (8 + 5) = (10 + 3). But that's not what the question was asking. The quesion that was asked wasn't meant to be understood, in my opinion -- this is the attack on reason by the attempt at making the world not understandable.

History is getting taught out of sequence to skew context. And the reasons things happen the way they did, as a consequence of what PRECEDED said events. Don't even get me started on the lack of classic literature being taught! Creative writing is going to be lost. Argumentative is what replaces it. Sigh....

Only if that person lives in a rubber room...

The only thing I like about Common Core is that some are starting to call it "Obamacore", it's got a special ring to it. I'm still trying to figure out the concept behind the "Number Line" thing somehow demonstrating that 427 - 316 = 111. There is little difference between Obamacore and "Michellecare". “The federal regulations restrict snack foods at school to only those with at least 50% whole grain, low sugar, fat, and sodium, as well as less than 200 calories." Damn, get out of our lives. Where does it say that the federal government tells us what and how to teach and what we can and can't eat. I would never have made it through school had it not been for the Snickers bar, and I was never obese, not even fat, just skinny as a rail (at least until now over age 70).

I looked at the first part of the video, but found it lacking in facts and full of opinion. I do not like CC but this would not be my approach to dismantling it.

It's really terrible. That would've destroyed me as a child.

I agree with Bobhummel. One looks to mathematics as a paradigm of the whole process because math is imminently 'answerable'.

I (a non-mathematician) feel that the problem is technically incorrect. If you ask in a word problem, "How do you make eight and five come out to ten with some left over." that is OK. But if you write: 8+5 then you imply that this is a sum...and the answer is NOT 10. Anything that implies that it is 10 is factually incorrect.

Jan, counts on fingers and toes

Helidrvr, that is a great presentation by Dr. Pesto in that youtube link. Thanks
Cheers

I discussed this particular problem with a teacher I know who is in favor of common core. I asked why this kind of thing is taught. Her answer?...They are actually teaching the kids (with this particular problem) to break problems into 10s "because that's easier to handle". See, something like times tables is too advanced now. While I appreciate her honesty...this leaves me chilled.

My life is built on math skills. I'm a professional engineer and also do work in the finance industry. I think common core is a disaster. I actually see it as assult on our children. They must be doing this on purpose. Nobody is so stupid to pass this off as an honest program...

IF they could complete it using this backhanded smoke-n-mirrors approach. My thought is they would have to go to the "authority figure" to tell them what the answer is - right, wrong, or indifferent.

Showing it's not a lesson in math - its a lesson in acquiescence and obedience.

The way I was trained, in the 80s and then in college in the 90s, is to set up an alegebraic equation to solve for 10. I would have solved for (a) by "moving over" 8 and 5 by subtracting them from 10.
a=10-8-5
a=-3
