It is very important to develop a rapport with your students, take the time to do this at the beginning of the year and maintain this through the year. Get to know your students. It may feel like it takes too much time from your teaching however you will gain time in the end as you will have less disruptive behaviours to manage in the long run. Ensure your students know you care about them but that you are firm when you need to be.
Make time in the day to listen to your students talk about things that interest them. Ask them about their interests, engage in conversation with them that does not relate to the curriculum. This will build connection and show your students that you care.
Be flexible. Recognise when the lesson you are teaching is not working. If you recognise this then change what you are doing. You can stop a lesson, reorganise and come back to it at another time. Disruptive behaviour can often be caused by students being confused or bored.
Develop a flexible teaching style, and recognise when the majority of students aren’t interested in the lesson, can you modify it to gain attention again. Sensing students' mood and motivation can help control disruptive behaviour.
Encourage a team atmosphere, encourage students getting help from each other as well as you.
