It never hurts to get a little "data" and motivation going in the music room. I would never have thought of this unless the students weren't already doing something similiar with their First in Math scores.
As each student earns a belt, I color a box black next to their name.
Of course there aren't many black blanks yet, but I literally just put this up. I'm hoping in another month or so we'll have everyone (well, 5th grade is pretty busy with their program stuff) at least on their purple belt, with many "blacked out".
