My first teaching experience went pretty well, though I could tell near the end (before we played a ballet version of charades) that the girls were getting a little bored. They were very well behaved (likely because they're not sure what to make of us yet, heh), but I still want them to have fun, so we'll have to see what we can come up with to make things a little more exciting.
I also somehow ended up teaching the beginning/intermediate adult class when the teacher had to cancel last minute. I only had three students (all of whom I've taken class with), so it was relaxed and quite fun. They were good sports, and I have a suspicion that I might like teaching adults over munchkins. I said something about it to the AD later, and she kind of smiled and nodded and said, "Everyone is different." It's obviously very early in my teaching experience though, so time will tell.
