Downloaded this game for my son – Sorting game for preschool kid Review

I downloaded this game for my son to play. He started prek in August so I was looking for a game to show him how to separate out the differences of things. For example while playing this app he is able to decide where he thinks it goes and if it isn't correct it will not let it stay there. He seems to like it pretty well.
