Adams and Pierce (gifted education and mathematical sciences, Ball State U.), who work with teachers to establish more effectively differentiated classrooms and provide professional development and consultation in math, science, identification, and program evaluation, provide math teachers who work with students in grades six through 12 lessons for differentiating instruction that were designed by teachers and are easy to implement and modify, encourage student engagement, and are appropriate for multiple grade levels. Lessons use exit cards, choice boards, cubing, graphic organizers, learning contracts, and tiers, and include instructions, examples, tips on how and when to use them, reproducible handouts, how they fit with their CIRCLE MAP model, and comments from the teacher who developed them on how to use strategies and how students responded, as well as comments from other teachers who used them.
