One of our favorite apps to use with PreK students is the PBS Parents Play and Learn app. I like the variety of interactive games that they can explore which review things like shapes, colors, size, numbers, and letters. Games have audio directions and get more complex as the game progresses. Our students epecially love the “Stickers” activity which lets them build scenes with a variety of sticker pictures. The app also includes hints and information for parents to go along with the games and can be switched to Spanish.
PBS Parents Play and Learn currently is free on the US iTunes store.
