Ok, so my 10 year old daughter comes home last night and asks me to help her with her "base 10 blocks" for proofing long division. Huh? so, anyhow, I look it up on line and after being utterly confused, I find a few youtube videos about it, and now I get it. What I don't get, is why these little hieroglyphic looking pictures are used to "proof" something that is super simple. My daughter has no trouble with the long division at all, it's only the "simplified" drawings that are confusing to her. Did any of you use this to learn division?

Be careful. Tooge will try to take your back and engage in a rear naked choke now.

According to this guy Common Core math is not up to international standards. Wonder what else is missing?

Dr. James Milgram (Stanford University emeritus professor who served on the official Common Core validation committee) reported:

I can tell you that my main objection to Core Standards, and the reason I didn’t sign off on them was that they did not match up to international expectations. They were at least 2 years behind the practices in the high achieving countries by 7th grade,and, as a number of people have observed, only require partial understanding of what would be the content of a normal, solid, coursein Algebra I or Geometry. Moreover, they cover very little of the content of Algebra II, and none of any higher level course… They will not help our children match up to the students in the top foreign countries when it comes to being hired to top level jobs

I never trust top down nationalization on education. It's a cookie-cutter approach. But there's a lot of other good information in that link on other things coming with Common Core. Look at the English, less literature but more reading of govt documents? Wtf? This doesn't make thinkers.

One of the first tricks we were taught in grade school was how to multiply 9s. Then I remember "is over of" to figure out percentages. Simplifying stuff came with fractions.

They've always taught tricks without making it the core curriculum. Wish I knew how much of our failure at math was because of how we were taught or because we're flighty teenagers as a country.

I think people can figure out some of those tricks they resort to in everyday use for math. I know I figured them on my own.

Start-Up Teaches Math to Americans, Indian-Style

Start-Up Teaches Math to Americans, Indian-Style

Indian Math OnlineScreen shot of Indian Math Online.

The New York Times recently reported on a study that found, once again, that the United States is failing to develop the math skills of its students, particularly girls, especially compared to other countries where math education is more highly valued.

Indian Math Online is a start-up that aims to take on that disparity by teaching math to American kids using techniques from Indian schools.

Bob Compton, an Indianapolis-based venture capitalist and entrepreneur who co-founded Indian Math Online, hatched the idea when he was producing “Two Million Minutes”, a documentary comparing high school education in India, China and the United States....

By testing specific subject areas, Indian Math Online picks up weaknesses that a typical school test would miss, Mr. Compton said....

Mr. Compton said that children of Indian and Chinese parents use the site consistently, but American children often lose interest after a couple months. He compares math to athletics — youths must practice a bit every day to master it. “For some reason, American kids seem to be willing to put in the work with athletics, but not put it in with the one subject that’s going to matter more to their lives than any other activity.” [ Interesting, as are the comments by foreigners at the bottom.]
