Candy corn - it's inexpensive and, well, somewhat durable. Perfect to use for a music activity!
I printed out this, Corny Melodies Staff, for each student (I guess you could also laminate it or put it in a page protector - might be a bit germy).
It works for any grade!
First: So and Mi melodies (or La too if you're there)
Second: So, Mi, La melodies
Third: Do-Re-Mi Melodies
Fourth and Fifth: Do Pentatonic Melodies or spelling 3-5 letter words on the music staff
The kids can eat their candy when finished! Yum!
