How have "monsters" been viewed in society, what purpose do they serve, and why are they necessary? In this language-arts-based curriculum unit for grades 9-12, students explore the ways "monsters" are depicted in literature, music, and drama. According to the unit, students will: define what a monster is; read the classic "Beowulf"; then read John Gardner's "Grendel"; and execute a concluding project which requires them to create, name, describe, and visually depict a "monster." The lesson presents an overview; suggests grade level; cites subjects and subtopics; lists equipment and materials needed; and gives teacher resources and extensive National Standards for Arts Education as well as other national standards and Virginia State Standards. It provides instructional objectives and strategies, followed by a detailed, step-by-step instructional plan for the classroom. It also suggests assessment and extension activities. (NKA)
