I've written about the interactive app charts that Kathy Schrock has created that organized different iOS, Android, and Google and Web 2.0 apps based on the Bloom's Taxonomy level. They are a great way to find Apps based on what you are trying to have the students do.
She just updated them with a new diagram for Bloom's Taxonomy. The new diagram is interlocking gears instead of a pyramid. It also emphasizes Creating as the biggest thing we should be having students do.
This is a great resource for all teachers looking for some great apps to use with students.
