I LOVE this!! She has the #firstday hashtag up for, obviously, the first of the school year. She's going to take a picture of each student and put their it on the board. Then she'll change the hashtag and pictures throughout they year. SO cute!!
Middle school bulletin board idea: "Believe in your #selfie" Have each student take a selfie and put it up with a #adjective that describes them. "Do something today for which your future self will thank you." The kids love seeing their faces in the hallway and it builds a grade-level community too.
