It's one of those days in Ms. Mya's classroom, when things just aren't clicking: Jamilla is jumping. Ruth is running. And Reese is roaring like a great big lion for no reason at all. But Ms. Mya knows what to do. She gathers up the children, and together they begin a conversation about expectations. "An expectation is something we can rely on, something we know is going to happen," says Ms. Mya. When adults guide children in a positive, proactive way by supplying them with clear expectations of what to do, when to do it, and how to behave, children learn to focus, direct their attention, manage their emotions, and regulate their behavior. A charming story coupled with equally as charming illustrations, When You Just Have to Roar! helps children and the adults who care for them make every day its best. The book contains a page of information to help parents, caregivers, and educators reinforce these important concepts and support children's development of emotional control and self-regulation. Rachel Robertson is the director of education and development at Bright Horizons. She has more than twenty years of experience in the education field and is the author of numerous early childhood resources. This is her first children's book. Priscilla Prentice studied illustration at the Rhode Island School of Design. Upon graduation she worked as an animator and eventually settled as an environmental artist for video games. When You Just Have to Roar! is her picture book debut.
