I started a new "Of the Week" this year: Musician of the Week to add to my yearly plans!
I do these about once every 2 or 3 weeks, though, as they can take up an entire class period.
The kids seem to really enjoy them! They're quick and to the point, with listening example links (links on some pictures) and a song to learn at the end.
Please let me know if you think anything can be improved!
