Sisters and Brothers: Sibling Relationships in the Animal World“>Sisters and Brothers: Sibling Relationships in the Animal World, written by Robin Page, and illustrated by Steve Jenkins, is a delightful book for ages 4 – 8, that explores the similarities and differences between animal siblings. Science Net Links (American Association for the Advancement of Science) put together a terrific lesson plan based on the story with the intention of helping students understand the numbers of animals in the world and how they depend on each other. It begins with the teacher first defining the term sibling and then exploring current sibling relationships among students in the classroom before reading the book. Its a great lesson plan for teachers who are looking for ways to help students better understand sibling relationships in general.
