or: How Long Can We Keep This Up?
We’re about to double up on equity around here. What happens now is at least twice as important as my Neanderthalic School-2.0 contrarianism or anti-anti-NCLB missives.
I’m convinced I have no right to be coy about my practices. Both because I talk a big game around here and because I feel very beholden to the taxpaying public, transparency is a moral imperative.
So this is everything. Every lesson, every handout, and every activity. Please use them. Use anything. This is Creative Commons wholesale. Get in and grab as much as you can get out the door. Handtrucks are available to your left.
Please criticize. If I receive even one substantive critique per week (perhaps a different or better approach to the material) I’ll count this additional timesuck worthwhile.
Please use Keynote. Depressing though it is, I’m posting the PowerPoint conversion. The market share speaks for itself pretty clearly on the matter.
All textbook problems have been sourced from Key Curriculum Press’ Discovering Algebra, First Edition, and Discovering Geometry, Third Edition, respectively. Comparable assignments specific to your own textbooks are left as exercises for the teacher.
It’s all on the table now.
Bad Habits. Apparently a winter break’s worth of late bedtimes and late waking isn’t that easy to shake. I set five alarms over the last two days and didn’t wake to any of them. I’ve never been late to a class, not even in the last two days, but 30 minutes to grab breakfast, make worksheets, and set up shop is far too rushed for my liking. I don’t know how some of y’all veterans manage it.
Veering Off Content. My algebra class and I played review basketball yesterday in order to shake off the I-Totally-Forgot-This. The rules are pretty much what you’d expect: answer a math question correctly, shoot a plastic ball into a trash can for points, maybe prizes. Just a little circus with their bread.
