Teachers, Change Your Bait! is a text grounded in the realities of classroom life. It is a thorough yet digestible mix of brain research, learning theory, and psychological principles with specific strategies and activities that enhance teachers' ability to differentiate teaching and learning in their classrooms. Particularly noteworthy is how each chapter concludes with Tackle Box Ideas which summarize the guiding principles that open each chapter. Martha's relatable “teacher-down-the-hall” style drew me into a conversation about learning that both validated and challenged my educational beliefs and practices. This book, in its entirety or by individual chapters, would make an excellent professional development focus on differentiation. Bravo, Martha, for placing a truly valuable tool in the hands of educators!
