That sounds awesome! I am glad that you pointed out you let the kids look things up when they do not know. I let my kids look things up in their notes and dictionaries if necessary, but as the game progresses, I give them less time to do so once I feel that they should know the answer. Do you use gestures during mind soccer? I have not tried it yet, but I think that when I go back on track I am going to start asking silent questions with gestures and have the kids tell me what the vocabulary that matches is, or possibly the other way around, I say the concept and they have to respond with the appropriate gesture. I am predicting that this will be a nice addition for the quiet kids that don't like to yell out answers.
