Unfortunately, there isn't a magic classroom management strategy or plan that works for all students with all teachers. You'll find that each group of students you have will need a slightly different plan. While teaching, remind students of what proper behavior is. For example, if you're asking the students a question, say "Who can raise their hand and tell me....." This reminds the kids to raise their hand and answer. Also, if someone does call the answer out, be sure to remind them that it's not appropriate and call on someone who is raising their hand.

For elementary students, the stoplight method works well. Green means they're doing well, yellow means the student has a warning and needs to check their behavior, red means that they should get a time out or other consequences, including a phone call home. You could also try a "money system" of classroom management. You can do a search for this method.

Finally, I highly recommend that you read the book "The First Days of School" by Harry Wong. His book talks about setting up procedures and rules and a classroom management strategy. I also recommend the book "Teaching With Love and Logic." This book discusses ways to develop relationships with students and lead students to making the right choices. Finally, I have heard (but haven't yet read) that the book "Setting Limits in the Classroom" is a good read for classroom management strategies.

Good luck, and remember there is no "one plan fits all" when it comes to classroom mangement!
