This performance guide is designed for teachers to use with students before and after a performance of "Lyle, Lyle, Crocodile," a musical based on the books by Bernard Waber, with book by Michael Slade, music by David Evans, and lyrics by Mindi Dickstein. The guide, called a "Cuesheet," contains four activity sheets for use in class, addressing: (1) What Happens in the Story (with a brief summary for students of the story); (2) Getting Ready To See "Lyle, Lyle, Crocodile" (with several activities that each introduces and aspect of musical theatre, including Understanding the Story, From Story to Stage, What's a Musical? Actors Pretend, Props Help Tell the Story, and with background on geography, languages, including some lines from the play); and (3) Going To See "Lyle, Lyle, Crocodile" (discussing the audience's important role in a live theatre performance, and describing visiting the Kennedy Center). Resources for further exploration are listed. (SR)
