I am substitute teaching 4 more shifts, this week and next. I still have a hard time remembering which class is which. I can't imagine that I will ever be a real teacher, since I have trouble remembering 4 student's names, let alone 25 or 30.
Today I have a class that I taught last week for the first time. The one boy in the class is kind of a smart-ass, until he discovered that I speak Japanese. I have to be careful not to let him know that if he speaks at native speed/vernacular, I probably won't understand him.
