Great site with tons of iPad apps for the classroom (and ways you can use it even if you only have ONE iPad). I use my iPad with my classes a lot. Tons of great apps (I use it with my Kindergarten kids) Literacy Journals, Schools Ideas, Ipad Classroom, Ipad Ideas, Classroom Technology, I Pads, Classroom Ipad, Classroom Ideas, Ipad App
Maybe it's time to bring an iPad to the classroom. One iPad for the class ideas. This is one of the better list of ideas I have seen.
