This is a great way to keep the volume level in the classroom under control! I use these in my classroom and in the hallways to help my students take responsibility in managing their voice level. It has been a wonderful visual tool! I use the “arrow” to indicate what voice level we are currently working at, and what level we need to actually be at. This has been such a successful tool, that often times before we begin an activity, the students will ask, “what voice level should we be at?” I have included 2 different sized signs and arrows and a portable voice level indicator card to carry with you when you leave the classroom!
