I love substitution songs, do you? These are songs where the subject is sung with a motion, then the next time the song is sung, the lyric is substituted with only the action. These kinds of songs were a favorite with my Orff Master's Level course teacher, Jos Wuytack. In fact Judy Sills adapted a book of his songs called "55X Funtastic - 55 Songs with Motion for Children". Not all the songs have substitution games, but most do and they are so much fun!
I recently found this substitution song, my students love it! This one is about that wonderful critter, the crocodile!
