1) Use the web to find and read several mathematics teaching statements. Find one that you like and one that you don't like, bring printouts of them to class and be ready to explain what you (dis)liked about them. Although you will probably end up reading about some good or interesting teaching practices or styles, try to focus on what makes the statement itself good (i.e. apart from the practices it describes).
2) Each bring two questions for the experienced graduate instructors.
