This is a fun activity to improve morale at work during the month of October! Includes Boo sign to hang outside your door and directions for everyone. Print out enough Boo signs for everyone in your school. I usually start 2 Boo treats going to get through everyone at our school, we have about 50 staff members. I usually buy the plastic pumpkins from Wal-Mart and fill it with tissue paper and throw in some treats and fun little Halloween items. I place the directions and Boo signs in both pumpkins and secretly place them on the desk of co-workers. The hardest part is keeping the secret that you started it!
