Our district is having us post our target goals for each class. For a music teacher, that is at least 7 classes a day, K-6th grade. I found this blue teacher chart to work well.

This includes the heading, as well as small grade numbers to post on the side.

I use sentence strips taped together and laminated to put into each slot. I just use a vis a vis or dry erase marker and change it each day.
