Why We’re Here:
- We’ll apply and derive translations from figures in the plane.
- We’ll discuss tessellations, which regular polygons tessellate, which don’t.
- We’ll get our hands dirty with triangles & quadrilaterals, devising a method for tessellating both of those.
Why We’re Here:
- We’ll understand the difference between rigid and non-rigid transformations.
- We’ll discuss the three kinds of rigid transformations and practice identifying them.
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.
Keynote for lectures. Keymath for online textbook access, supremely useful for anywhere-planning and for projecting classwork pages on the board. KeepVid to extract YouTube videos. VLC Player to play them. Vixy for QuickTime conversion. MathType, LaTeXiT, and LaTeX Equation Editor for formatting math notation. PowerSchool for grades. Google Docs for to-do lists. Google Calendar to track and remind me of meetings. YouMail to manage voicemail. WordPress and coComments for blogging (though I’m hardly committed to any comment tracking system).
