Apps for the Primary Grades

There are some good FREE apps for education to be used on an iPad.  These apps are stand-alone, meaning that the app is a game-like activity that the student can do independently.  Many apps that are free also have a paid version.  So some of these apps only allow certain parts free.
Do you have any additional free or paid apps that you think are good for Primary students?
