Teachers can apply for FREE group video calling to use it in the classroom. Many were moving to Google Hangouts because you can use 10 at a time, but now you can do it on skype if you're an educator. APPLY NOW, while you can.
I have some sample "Magic erase sheets" in my classroom and LOVE THEM. You can stick them to ANY wall. They make them gridded or plain and they stick everywhere. I've been using dry erase boards but the problem was they wouldn't stick. So, now, I can use these and stick them anywhere. I love them. I'd get a box of sheets and use them in the classroom. Very cool.
