My class has one iPad. Just one. But I have found ways to put this single iPad to use in such a way that everyone in my class benefits.
Having mastered one app -- the Show-Me app -- I have been able to create podcasts for my students, allowing them to access my help on their assignments while they are at home or when I am unavailable for face-to-face teaching or tutoring.
After I became comfortable with using this app, I began to brainstorm ways I could use it within my classroom.
