This year, I decided that all my bulletin boards will be musical themed. For my welcome back board, I used "The King and I" for my theme. On different colored fans, student wrote their response to my question on the board.
"If you could be any where right now, where would you be?"
This caused a lot of laughter and story telling about what they have been doing this past summer. It was a great way to get to know my students within the first week of school.
