I had a class of 10 yesterday and several kids were itching to join in so we said, "sure, bring them." I wasn't sure how it would work, if the kids would keep up, or if the adults would feel I watered anything down. But it worked out beautifully. The class was basically the same as a regular adult class and the kids had no trouble keeping up and understanding everything. As in any class I teach, when they got going you could hear a pin drop. I challenge you to look at the mosaic of their work and see if you can pick out which tiles were done by the kids. I know I sure couldn't tell!
