Survived the first day. Considering what I observed with the sub last week, the kids were remarkably well behaved. So much so that I'm almost waiting for the other shoe to drop. No sense in that, though. Assume they're good kids, assume they want to do the right thing, and you'll be proven right. That's the theory, anyway.
Lots to say -- I certainly rambled on for two pages in my paper teaching journal -- but for now it's after 11pm and I need to go to bed. I'll outline the math lesson in the morning.
