The BEarded Math Man is posting some videos and … oh, Sal Khan’s got nothin’ on him : )   “Binomial reproduction” is one approach to factoring, with the analogy to “who’s the father?”  to figure out “where did this come from?”   If I were an adolescent I’d be luvvin’ it.   (Now, it […]

I really do oft reflect happily about our Math courses being taught for understanding, and speculate that I’d find another job if they weren’t.

Need to get away from twitter which has a mess of stuff from another open education summit.  Sour grapes. I did the next two (now down to 16 lessons) ALEKS lessons … the figuring out angles and sides of a triangle with laws of cosines and sines.    Talk about exercises in precise attention to […]

Possibilities abound.   EngageNY is looking for “fellows” to help develop their curriculum.  Oh, my, it is full of the vilified “not your parents’ algorithms” terms like “Hide Zero Cards,” which a quick search informs me are manipulatives for reinforcing that, say, 13 is really 10 + 3 — you represent 13 with a ten card […]
