I loved the voice level charts I've been seeing on pinterest. A large sign would be nice but in the interest of saving time I created one on my computer. I plan on printing it out, hanging it in a central location on the chalkboard and using a magnetic arrow to signify which voice the students should be using. You can download my chart by clicking HERE.
Below are some of the photos I've pinned. you can view more HERE and HERE. Enjoy!
