Minimize Noise
When students are active in a classroom, there will be some noise. There is no need for the noise to become oppressive or distracting.
From the beginning of the year, work with students on working with peers quietly. Teach them to whisper or talk softly.
Use a signal to remind them to reduce the conversation level.
Some students are especially distracted by noise. Finding a section of the room somewhat removed from the noise may be helpful for them.
Remember to involve students in conversation about balancing their needs for conversation and concentration, and let them help you find other ways to retain both.
