Their has to be a goal in mind. Teaching using technology has to have planning or or or you might just be wasting time in a cool way.
I like the idea of accountability and the use of questions after workstations or practice. Once again, what is the objective/plan?
Maybe Learning Games for Kids or Thinkfinity. Some of the lessons were too low level so would have to do some research on apps. etc. to see what will benefit my students.
I really like the idea of using the ipads for Partner Journals or for that matter Group Journals. Use the ipads to pose a question or prompt or just a conversation and then have students add to the "activity". For ESL students this is again a great way to (learn see touch) a new language.
