The first app that I found very useful for education was Teacher's Assistant Pro. This app lets a teacher put down student's behavior on a daily basis. Tracking a student's behavior, negative or positive, will be beneficial for teacher's in the long run. Sundry Notes looks like an all around useful app for teacher's. A teacher can use this app and this app only because it is an all purpose application for the iPad. I really like that it allows for recordings. Some times its easier for teachers to record their thoughts or lectures compared to typing them on the iPad. The virtual graph paper that this application comes with can allow teacher's to do things that they would normally do on paper except normal iPad software does not have it.
