One of the great advantages of TeacherPlan is that it puts all of your lesson ideas straight into your iCal calendar. So you don’t need to worry about not being able to get a copy of your lesson plan because the printer not working (again). Being able to check your lesson plan on your phone means less waste paper and that has to be great for the environment. I have taken a look at an Android app called Revunote which may even let you bypass the need to check your calendar, by having you remember everything. Revunote is a brand new way to help you remember things, worth checking out.
