Classroom B-day idea... or just a great community builder mid-year. This is seriously one of the sweetest ideas I have ever seen. If there is no smartboard in your room maybe you could do it with large bulletin board paper. Then they could keep the kind words.
Classroom: My whiteboard organization! I used black electric tape to grid my white board. I printed signs for Monday-Friday, weekly agenda, bellwork, today and objective on my computer, glued it to black paper and laminated them! Then taped them up! This helps to keep me and my students organized! :)
