Choral music that requires members to play instruments (i.e. percussion)

I am a college student, working on a Choral Methods assignment. I need to address an underdeveloped area of practice. In my opinion the 2nd National Standard for Arts Education is not adequately met in practice: "Performing on instruments, alone and with others, a varied repertoire of music." I would appreciate receiving input from choir directors out there. I specifically am looking for Middle School or High School choir music that calls for members to play percussion instruments, or bells, boomwhackers, or whatever, as well as sing. I welcome advice from those of you who have performed such music. Thank you!
