The MS teachers ask for the class to donate to the teacher's favourite charity in place of a gift. Obviously, no giving is madatory, but I really like the idea. Since we have 3 different advisories (Homerooms) we will be donating to 3 different charities. 
I guess they got tired of mugs. 
Oh-in elementary school- the moms would get together and collect say $5-$10 per kid and get spa gift certs for the teacher.
