My teacher uses a Noise Meter similar to this one. The Noise Meter is a cool way to remind students the correct noise level that they should be using! You just use the paper clip and move it to the appropriate noise level the students should be using.
My classroom noise-o-meter. I have an arrow that sticks on the board to indicate the allowable level of noise, depending on the activity. Feel free to use or share…send me a message if you would like an editable MS Publisher file.
