Traffic light system for giving warnings for misbehaviour in the classroom, in a calm, non-confrontational way. Green cards for children who are working hard (especially if this out of the norm!); orange for a first warning and reminder of the golden rules; and red for a final warning before sanctions arise. Children receiving warnings can earn a green cards by getting back on task. Can be linked to class reward system, e.g. team points etc for those with green cards at end of lesson.
