The role of a math coach is demanding and often undefined. Many math coaches feel unprepared to meet the enormous challenge of helping schools improve math instruction. In this edited collection, veteran math coaches share their expertise, providing glimpses into the unique trials, false starts, and successes they have faced in their positions. The authors ask and answer such questions as: What makes an effective math coach? What are helpful strategies for supporting both eager and reluctant teachers? What pitfalls do math coaches encounter and what can they do about them? Written by coaches for coaches, this book is also an invaluable resource for teacher leaders, school administrators, and mathematics supervisors.
