Jitters!

Tomorrow is my first day of school and I am so excited and nervous.  I know that everything will be great but I can't help but feel the first day jitters.  I have a two-week assignment teaching middle school math and my day will go from about 7:15AM to 2:30PM.  There are seven class periods but I might get a prep period.  It's a little scary not knowing much about the job until a half-hour before class but I chose the two-week assignment so that I could have a little more consistency (not to mention guaranteed work for two weeks!)  Anyway, here goes!
