Classroom management in different age groups

Set effective limits.
Review and post your classroom expectations so that they are clearly visible. Expectations should be clear, simple, and stated positively as what you “can do.” For example, instead of saying, “No side talk,” say “Please raise your hand to add to the conversation.”
Keep to the schedule you set.
Following your own expectations is key to modeling timeliness and productivity. The more organized you are, the more opportunity there is to focus on teaching and learning. This will help your students respect schedules and work within designated time frames. Remember that while, as a general rule, consistency is important, it may sometimes be appropriate to address a student’s needs even if it interferes with the schedule or routine.
Be aware of the causes of behavior.
Be mindful of Precipitating Factors—preexisting circumstances that cause distress behavior—and early warning signs to help you focus on prevention. If a student seems consistently irritable or inattentive in the morning, could hunger be causing the behavior? Could you make sure the student gets breakfast in the cafeteria before class or keep granola bars in your desk? Keep in mind, classroom management is not just about avoiding student disruptions but about creating an environment that enables students to focus on learning.
Engage with students.
When a student is inattentive, rowdy, or challenging, it distracts others. As you’re teaching, try making friendly eye contact with the student. Encourage them to focus on what is being taught by asking questions and using names. Remember that sometimes disruption is just misguided energy that simply needs to be invited into the conversation.
When students know what to expect from you, and what you expect from them, they’re more likely to be productive learners. Put these effective classroom management tips to use to manage disruptive behavior with confidence
