The document discusses four rules of effective classroom management:
1) Get them in - Teachers should greet students, assign seating, and immediately engage students in a warmup activity when class begins.
2) Get them out - Teachers should conclude lessons with consolidation of learning, give advance warning to stop work, and establish an orderly dismissal process for transitioning students out of the classroom.
3) Get on with it - Teachers must keep students actively engaged in learning activities throughout the lesson.
4) Get on with them - Teachers should build positive relationships with students.
