Student teaching

My host teacher is going to be gone this Thursday, and its also the day my teacher for my class is coming in to observe me! I'm a bit nervous, because I have to teach the entirety of 6th hour by myself, but i like the class, and they seem to respect me. I also came up with the lesson because we just got done reading a book, so we're moving on to a project to end the unit! I'm looking forward to it, but i'm also scared half to death.
