Wedgies in precal and the legend of congruence in geometry.
Got some sleep last night, and working through my "how to read your test scores" lesson with the kids. Lots of resistance. They also told on me to the principal, who sat through my 2nd period rendition and totally backed me up! Lots of parent emails coming in, but I'm dealing.
The kids, at least in a couple of classes, are starting to get it, too. They're asking really good questions, and you can see in their faces when they start getting over the shock of "Mr. Jon thinks 85% is good" and start realizing "I know how to get 100%". Hopefully that will start permeating through the ranks soon.
Actually, hopefully they'll stop thinking about those f*cking percentages altogether... One can dream.
