This is a template for a noise check system that I use in my classroom. When you purchase, you will print out each page and laminate them. I used colored ribbon and hot glued each circle on the ribbon underneath the 'Noise Check' sign. I then use a clothespin and pin the circle that shows the appropriate volume my classroom should be at. If the pin is on "shh.. Silent" and my students are talking, I say "noise check" and they repeat where the pin is at.
It has worked very well so far in my 5th grade class! I can make these in different colors as well!
