This is an intensely practical work for the many teachers who want to differentiate the lessons in their 6 through 12 classrooms. Feeling the usual pressures of limited time and testing, they are often frustrated in their attempts to accommodate abilities and learning styles. Juggling the varied needs of their several groups of students becomes so unwieldy that they often give it up. Adams and Pierce use their experiences as teachers of gifted students, and later, teachers of teachers, to craft strategies and templates that are clear and usable. Many teachers they have coached contributed lesson samples and techniques, showing the techniques in practice.
