Wow. amazing to see only 10% loss for a 0-2 min video.
Why Do People Stop Watching Videos, And What Can You Do About It?

Excellent resource: from +Wistia walks through the nose, body, and tail of videos and shows how to retain your audience. I'm paying close attention to this for Whiteboard Fridays!

Pretty much what people will be doing when CC goes out. Writing letters to explain why they don't understand CC, and explaining why they can't explain it. CC is an #epicfail and there's nothing you can do but site letters to parents explaning why the system is falling their kids. The only thing to do now is assign blame for who isn't fighting it.
Common Core Epic Fail!

Also see appended edited comment below.

One father, who has an advanced engineering degree, couldn't figure out the approach used to calculate a math problem presented on his son's elementary homework assignment: “Jack used the number line below to solve 427 – 316. Find his error. Then write a letter to Jack telling him what he did right, and what he should do to fix his mistake.”

“Dear Jack, Don’t feel bad. I have a Bachelor of Science Degree in Electronics Engineering, which included extensive study in differential equations and other higher math applications. Even I cannot explain the Common Core mathematics approach, nor get the answer correct. In the real world, simplification is valued over complication. Therefore, 427 - 316 = 111. The answer is solved in under 5 seconds — 111. The process used is ridiculous and would result in termination if used. Sincerely, Frustrated Parent.”

Edited: I posted this as a silly joke I've seen floating around Facebook, but it's turned out to be an annoying political kind of serious debate issue, it seems. So I'll qualify this with a serious comment as well. Btw, it may just be an urban legend -- and it might not have anything to do with actual 'Common Core' curriculum problems.

First, I think teaching difference (or sum) of numbers as distance is useful, and in general anytime you can visualize something abstract in a concrete geometric way, you can get a better intuitive understanding of what the math is actual doing. This particular one isn't to scale. Btw, the error is obvious to me instantly: he forgot to count off the 1 ten and skipped it, and just subtracted the hundreds and the six ones, and so was off by 10 in the end, so he got 121 instead of the correct 111.  

I've taught negative numbers to 2nd graders by introducing them to vectors. One girl showed me a proof of how 3-5 was impossible: she put three of her pencils on her desk, and said, "I can take away one; I can take away 2; and I can take away all 3; but I can't take away 5 pencils when I start with 3 pencils. It's downright impossible." (Boy I wish I had a video of this to post to youtube -- she was awesome. )

So I responded that was a wonderful proof; but that the reason you don't hear older kids say "take away" and say "minus" instead, is that subtraction isn't really taking away -- rather, it's moving left on the number line. So I showed them that if you add, you can put arrows head to tail of the two numbers you are adding, and at the end is the sum. And subtracting, you are adding a "minus number" that points the other way. So I had her, and all of them try it again, on the number line on their desks. They complained, "but the number line stops at zero!" And I said, "in kindergarten, then don't even have a zero -- their number lines start with 1. Well, this is the real answer -- we extend the number line left, just as we do to the right, and now we have answers to all these kinds of problems."

And so that same girl did a new proof: "Ok, I draw an arrow to the right 3 spaces; and then at the pointy end of that arrow I draw an arrow pointing left 5 spaces for 'minus 5' and then at the end it's 'negative 2'. That's the answer." And I said, "you got it!" 

Hence, if the illustration is clear and understandable, I think the geometric version gives an intuitive sense of what you're doing. 'Upgrading' that little girl's (and her classmates') algorithm for subtracting was crucial to her intuitive understanding. That's what this pic is also trying to do, but it's just a bit confusing, that's all. The point of the visualization is to give you an understanding how the mat works: you don't want to solve problems that way. In general, I think that if you can demonstrate a visual proof of an arithmetic or algebraic equation, you can get kids to 'grok' what's going on much better. Btw, I also introduced them to multiplication as adding in two directions, making a rectangle, and then counting up the squares in the rectangle. Worked great. But again, that's a visual tool to sharpen intuitions; you wouldn't ever rely on solving problems that way, either.

Sadly I admit to being a victim of Common Core. I had a hard time with mathematics growing up. I was in college before I was able to get a grasp on many functions. I remember reading CC test questions as a kid and feeling so confused.

4 Days In Cincinnati On Exposure by Justin Leibow

"To be clear, Cincinnati gets a bad rap. And namely from the people that grew up there and left. They simply cannot believe that the place has had a miraculous resurgence in the last 10 years. No joke, hard work and a fair amount of gentrification has rehabilitated entire neighborhoods that were once abandoned. 

I experienced world class accommodation, delicious food as fine as anything I am familiar with in LA, Chicago or New York, wonderful architecture along with smart, kind and wonderful people... Read More -

What Is Dyscalculia?

There have always been plenty of students who struggle with mathematics, however in recent years research and studies have shown that this may be due to a neurocognitive disorder called dyscalculia. Dyscalculia is a neurological disorder that prohibits the brain from understanding basic numerical and arithmetic concepts.

You'd think it would be faster to have 3 machines doing the different wires... But that's pretty cool to see in motion.

I agree. Just think how fast it would be if it was only doing circles.
