Since I plan to be teaching in Middle School, I would have to make sure the art is appropriate. I have been using the app for about three weeks and have noticed about one or two paintings from renaissance and baroque era that may be too risqué for that age group. If that was the case we would have to skip bell work that day or find other arrangements. What I like about the app though is that you can go back to the days before, so this could be helpful in planning and managing bellwork schedule.
