One the topic of interactive whiteboards, if you have a SMARTboard or Mimio or whatever kind you might have, do you stick with ONLY ink or notebook files? Or, do you also use powerpoint files?
If you DON'T have a SMART or Mimio, do you use Powerpoints as interactive lessons? I love to make SMART/Mimio lessons, but have been thinking more about PPT as ANYONE can use them.
Is there a preference?
