Go ahead and Google it — one of those “great songs of the sixties” that was really from 1971 🙂 I thought today was massively unproductive — put together 1.7 and 1.8 but I thought they were done last week and… 1.9 is exponents.  As with the multiplication… I felt the concept was too important […]

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. Summer courses… ugh.   Tech math so they’re allowed to use calculators for everything, including algebra problems like z/2 – 2/3 = -1/3z + 1/6 .   No, there’s no context […]

I know, I know, students are fond of the alligator always chomping the greater number.

Formulae are abstract.   Substitution into a formula can be a meaningless machination.  No longer, for the student who explained what we’d have to do to find the missing length knowing perimeter and side of a rectangle… double the width and subtract it from the perimeter.   Well…. I showed him the substitution process and […]

Endorphin-induced thoughts…

29 degrees and not much wind at all … and I got out a little early.   I could hear talk and laughter from one early-party group this “Unofficial Saint Patrick’s Day.” Imagining having funding. Imagining organizing (!yes, I think crazy thoughts on bike rides) the Urbana-Champaign node of OER innovations.  The technology and its […]
