Using paper helicopters to teach English

I was on my own today to teach a lesson so that the students could begin to hear English in a conversational manner rather than repetition of phrases. For the most part the day went well (hey, teachers, there are always a few who try to go "too far"). Anyway, we used paper helicopters, groups, and, finally, exploration. You can only get done so much in 40 minutes, but you can see that we found a great place in the school to lauch our helicopters. The students had great fun!!
