I wasn't on my A-game the first couple days of school, but now that I'm actually teaching math (instead of just introducing myself and talking about behavior, procedures, etc.) it's going much more smoothly.
I walk all the way over to the office once a day, and I have to make sure I have plenty of time to make the round-trip because I certainly can't run to class when the one-minute bell rings!
One ibuprofin a day seems to keep soreness at bay, although some kids have told me they've seen me wince once in awhile when I try to do something. Oh well, it's not like I can keep it a secret! The cane, which I sometimes use, is a dead giveaway!
