I am always on the lookout for when students are doing what is expected. In order to help encourage this, I mail positive notes home to the parents.
To make this easier on myself, I place this sign out, along with blank envelopes and pens, at back to school night and during meet the teacher. Parents write their name and address on the envelope, and then I don't have to take extra time to look up the address.
I have included signs for kindergarten through 5th grade.
