Do you know what to do with

180 students in Grade 3? Apparently I offered to teach in a elementary school tommorrow where they will shove me and 180 in a lecture hall for about an hour. Any idea's would really help :)

As for treating people to lunch... its what I love to do here. A forienger from Holland came to check out the school just for kicks. So she saw me teach some classes as well as the school and what it's about. Then I invited her to lunch, on me. You know ever since I've been in China people have been inviting me to lunch and taking the bill well today I showed them, I did the same! and it cost me about 5 rmb or 60 cents Canadian for lunch too. A heavy hit, but I think I can stomach it.
