I think I will find a way to do this Unwritten Love Letter lesson with my 6th graders next year. That means I can start collecting old, used envelopes for them. Neato. :)
Whiteboard paint. Maybe I will paint my entire classroom with this stuff, from floor to ceiling, wall to wall. Not really, but it might be useful to cover old chalkboards or to turn a cabinet door into a message board surface. Neato.
