David: I know that kids are interested in games, but before choosing this game to teach, I didn't consider how it would fit with my son's level of cognitive development. At 6, almost 7, he's just in between preoperational and concrete operational, so this would mean he could start to logically deduce more things if I left them for him to figure out. For example, maybe I could ask a question like, "Okay, so when we add together these numbers, we get a number higher than 6, but we want a number less than or equal to 6... so what do you think we should do?"
