I'm always looking for apps, in all subject areas (Math, Geography...), that have differentiated ways of successfully helping students learn from grade 5 to grade 9; especially needed are apps that will allow students to manipulate the patterns used/needed in writing, reading, math...Really good ones are hard to come by. I've had my iPad since the April 2010 release date. I can't recall a day since then that I haven't used it. I'm an ipad accessory geek (sadly, I've tried many different keyboards, cases, styluses, lap buddies). My favorite Note taking/PDF editor/Book Reader (marker-upper) is UPAD although there are several other great apps out there (GoodReader and Noteshelf for their own unique skills). I'm still looking for a way to save PDFs from Safari to any of my pdf apps. If anyone has a suggestion.
