These have been AWESOME in my room this year!
My younger kids have practiced putting the notes on the lines and spaces, and made a reminder visual to keep in their recorder folder. Soon, my junior high students will be using these to create chords, and another group will be using these for bass clef.
I can also use these in conjunction with my Rhythm Manipulatives
All of this can be found in my TpT store if you click the link on the title page for the products, or the TpT link on my sidebar. Sorry the pics aren't in use pics! I'm out of town for a funeral.
