Such a sweet idea for teachers to do in their class! 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.
What a great idea for my "What are you looking at" wall!! Instagram picture of the week! Each week I will put up a picture of something great that happened in class, and write fun little comment on the bottom. I will leave space for students to comment or "like" as well!
