I used your Back to the Board activity in my Japanese elementary schools. They were learning classroom vocabulary (pencil, eraser, blackboard, etc..) and "Whats this?" The students had a lot of fun with it. They used a lot of gestures rather than English though which gave me the idea of making word webs for the target language. Hopefully it will help build up their vocabulary. Thanks again for the idea.
That's Great! Thanks for posting your experience.
