I have already done a detailed post on advanced Dropbox tips for teachers, but I also wanted to do a more general post about cloud storage, give you some options, link you to some important apps, and explain why cloud storage is so important for students and teachers.
One thing a lot of teachers probably wish they had in the classroom is a fully-featured scanner. If you have iPads in the classroom, having a scanner would let you create digital copies of all those primary documents, old worksheets, and other resources you've amassed throughout the years. You could easily share copies of this stuff via a classroom website or resource folder without having to waste the time or paper running to the copy room. Students could just load up the scanned material on their iPads.
Well, if you have an iPad, then you have a scanner.
