Appropriate (and fun!) for all levels of ASL student, this class activity focuses on expressing meaning through facial expressions and body movement. In this activity, the entire class participates: Helping the "performing" students to visualize stories, shifting away from English grammar and linear thinking. For students in the "audience", they can begin to visually understand that they do not, in fact, need to rely on English grammar at all to convey and comprehend meaning.
One of my class favorites: This activity gets students out of their seats, forces them to challenge the language paradigm in which they normally think, gives everyone a chance to participate and encourages class cohesion!
