I just purchased an app to replace our All About Spelling magnet backed tiles. Sound Literacy is the AAS board for the iPad. It is very, very pricey for an app, but it’s worth it for me. I love the portability, the lack of tiles to knock off and lose, the ease of putting phonogram tiles back, etc. I just thought I’d share in case others are interested.
