Yeah make sure every kid gets to talk. I make sure that happens by making a review PPT for the beginning and end of class. I don't have big classes so it's easy enough to put in 10 quick questions at the beginning and 10 at the end, each with a student's name on it so they HAVE to answer, the parents know/think that i know their kid's name, and so I don't accidentally forget someone. I tailor the questions so the different levels too so that I know the kid will be able to answer properly.
