There were a few that I would recommend from the list that appeared today:
1. SimpleSort - normally $.99 but FREE TODAY! This app allows students to work on their sorting and categorizing skills. Students have to drop and drag items into the appropriate bucket.
2. iMashup - normally $4.99 but FREE TODAY! Create mashups and remixed from songs in your library with this music app. Although it might not work with our students, as they can't download music on their iPads, it might be a great one for music teachers and music lovers alike:)!
That would probably be it from today's free ones!
