Disclaimer

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.
