absolute value

IT's classroom observation time. (Duly noting that oh, my, the wireless signal is a lot stronger on the other side of the room.) Under the influence of Making Math Real, I'm appreciating that even at college level he's giving more than one time to see it and hear it and practice it... and this is something painfully obvious that mastering it visually *and* algebraically makes its little nuances a whole mess easier. So "doing the left one first" is counterintuitive algebraically but *not* meaning-of-absolute-value wise.
Four weeks 'til Spring Break. There Will Be Podcasts. (Before if I can do it.) First for pos and neg adding. THen for absolute value. WHich those notes are online, happily :) (and not on Angel so any slob can get to them, thank you.)
Note to aspiring learners everywhere (hey, maybe I could email the GT/LD list and tell 'em)... there's stuff online so a person could learn. Some of it is hard to find but lots of it doesn't even have a password.
