This guide is designed to provide classroom teachers with an over-view of the key criteria for the Essentials model, complete with multiple sample techniques for each element and practical advice for their implementation. Educators who have begun the process of implementing standards-based learning in their classrooms will find that this is the essential flipbook for achieving rigor.
