MathFileFolderGames is an excellent company that specializes in making fun iOS games for Math. The majority of these games are blue-tooth enabled that allows students to play against a friend or classmate on separate devices. Also, these games have an email button that makes it easy to share scores w/ parents or teachers. Finally, these games cover a wide range of subjects (i.e. Fractions, Order of Operations, Tangrams, etc), and make it easy to create a 21st Century Classroom w/ centers and mobile learning.
