Drop a Note for a Friend!
The anti-bullying program at our school teaches that "silent witnesses", the ones who are aware of bullying incidents but don't report them, are just as harmful - and accountable - as the bullies.
The box is in an out-of-the-way spot by my desk, so students can let me know what is happening to them or to others by dropping a note into the box without others seeing them do it. This serves two purposes: 1) The reporting student feels safer, and 2) being aware allows me to keep an eye on specific situations and do a little friendly questioning. Will I get some unsubstantiated claims? It's possible, so being aware is even more important. I like knowing that my students can communicate with me on this important issue.
