I almost deleted this resource recently. I'm still proud of some of its individual lessons and discrete ideas, but I first posted this when I was a fourth-year teacher and still pretty obsessed with classroom management and my own authority. My teaching has changed a lot since then, mostly for the better. You can find the stuff I'm most proud at threeacts.mrmeyer.com. I'm leaving this up but please be a critical consumer. Some of the ideas on this shelf are long past their buy-by date.

This supplement comprises thousands of slides and 2.64 GB — a lot of a/v content, in other words, some of which I did not author and do not have explicit permission to republish. Sorry about that. Every respect has been paid to Fair Use. Every effort has been made at attribution.
Textbook assignments and certain diagrams, for example, reference Prentice Hall's Algebra 1 (California Edition). The opener miscellany, for another example, is lifted from both Snapple® caps and Vital Statistics, a reference text which is just as good as Snapple® but in a different way. If you are a copyright holder (or know one) and I missed your attribution, please let me know via dan at mrmeyer dot com and we will make that right.
The rest is yours to use under a Creative Commons attribution license. This supplement is provided as is. Your suggestions are welcome and appreciated but, due to time constraints, this is not a wiki. [Update: here is a wiki.]
