I am always on the lookout for books about islands. Exploring the concept and imagery of islands, within a dance class, is a great way to talk about self-space and general space. It also goes hand in hand with the concepts of stationary/axial movement and traveling/locomotor movement.
An Island Grows, by Lola M. Schaefer with illustrations by Cathie Felstead, is a picture book telling the story of how volcanic islands form. The book begins "beneath the sea," and ends with an island inhabited by people.
You might not make a dance about the story, per se, but the book can be a nice introduction to a lesson for students in K-2 classes.
