My kid thinks it's a game, so that is wonderful. I love that each set of cards progresses as skills are learned and that the whole system is grows with them for both math and reading! I am trying to collect them all because my 1 year old will be able to use them in a year or so especially since he is always watching his big brother "play" with it. Pretty awesome that a four year old can sit and learn these skills on his own terms and then see if he is correct or not without anyone knowing. I think that really builds his confidence.
