I initially designed these because I had a student who would experience anxiety when going into a new or not frequented classroom. Every morning I would give the student "mail" to deliver to the teacher in a room he would be visiting on a regular basis. It really helped him feel more welcome in the building. They can can be used with students, staff, or family to provide a little lift to their day. Great for sticking in a work place mailbox, family members lunch box, or just about anywhere. Great to use if your school has a Bucket Fillers program.
