The 29 cases in this book are written by classroom teachers who hope that by sharing their experiences in teaching some of the most difficult topics in mathematics, others will learn. Each case presents a problematic situation intended to evoke thoughtful analysis and reflection about teaching and learning.

The case discussion model is presented as an approach to teacher development that can become self-sustaining within the culture of the school and the classroom.

Finally, the cases are presented as an opportunity for teachers to build their own mathematical knowledge as it relates to real classroom situations.

A companion facilitator’s guide is available.
