Have you had a chance to try Padlet.com? It is a free digital bulletin board that allows collaborative student work to be created simultaneously, accessed remotely with password protection and allows for upload of text, photos, Internet links and even video. With minmal instruction, classrooms at Heartland have already jumped onboard and have created and shared social studies pen pal class projects and even designed their own classroom newletter.
If you would like a one-to-one tutorial on Padlet, drop me an email.
I'd love to walk you through it!
