Classroom management involves organizing the classroom space, grouping students, using time effectively, and interacting appropriately with students. Good classroom management includes being aware of proximity to students, considering the effect of physical behavior, moving around the classroom, and responding to what students say. Teachers should speak audibly, vary the tone and quality of their voice, and breathe correctly. Motivating students can involve role-plays, visitors, pen pals, group presentations, debates, and concerts. Managing constraints requires explaining the purpose of activities, getting student feedback, and showing connections between activities. The teacher's role also includes relationships with other colleagues.
