I'm teaching a lesson this week at a school to which I have already interviewed. The p called to inform me that I made the short list of candidates the school is interested in, so he wanted me to come in to teach a lesson. He gave me the topic- Asia- and said the students just started studying the region. So, my question is: where do I start? This is almost too open-ended for me, especially since I don't know really anything about the class.
