Great sub tub activity! These will be a hit with the students and will allow your non-musical substitute teachers to teach content without needing a music degree. She or he will love it!
Kids love Fortune Tellers, Cootie Catchers, or whatever else we've called these origami wonders over the years.
Have students color and cut out the music fortune tellers. They will fold them into the shape using the easy-to-follow directions on the worksheet. After that the fun begins.
I've used these successfully with grades 1-7.
