The Halloweiner by Dav Pilkey
My students love The Halloweiner. We read it each October. I teach the song, then we sing it on each page turn.
I have my students improvise an accompaniment on the Orff xylophones as we sing.
We also add sound effects with percussion, such as:
any time anyone walks or runs- temple blocks
roll on bass drum when the monster rises out of the graveyard
guiros when Oscar rips the costume off
ocean drum when Oscar jumps into the pond and swims
