Well... DUH!

I was reading an article about how math teachers aren't teaching kids well enough at the very young ages (and probably because the teachers themselves don't know math well enough), and followed a link to an older article about how to teach kids math better.

While the article waxes poetically about "teacher-centered" vs. "student-centered" learning, and other physco-babble, they do say the basic point is... "Hammer the basics". Otherwise known as practice, practice, practice.

That sound you are hearing is your throat trying to choke down your reflexive need to shout "DUH!"
