Do you fifth grade teachers use any noise meter charts to display to students what the current classroom environment expectations are? Charts that have something like indoor voice, whisper voice, no voice? I like the idea because it reinforces the expectations visually and can be helpful for ell students. I know it is used with younger grades effectively. I do not want to baby my fifth graders but I also want very clear expectations for them. So do you use any such tools in your class?
