This booklet provides instruction, for the director of junior high and senior high school plays, in the effective arrangement of characters on stage. Suggested exercises include the construction of still-picture tableaux on stage (using scenes from fairy tales and Chekhov's "The Bear") and the implementation of "blocking" techniques, using notation and chess pieces to visualize the purposeful movement of live actors. Guidelines are specified for evaluation and feedback by instructors and audiences. (KS)
