Becoming Butterflies

The team behind One Bean and Pumpkin Day, Pumpkin Night join up for a lesson on metamorphosis in Becoming Butterflies by Anne Rockwell, illus. by Megan Halsey. Cut-paper collage creates a three-dimensional effect in Miss Dana's classroom; the students' pictures record the chrysalis stage and the butterflies' emergence. Front endpapers label different caterpillars, while the back endpapers picture the butterflies they become, labeled with common and scientific names. (Mar.)
