I knew about Dr. Peter Liljedahl's work having read some of his papers and reviewed his presentations, and I have been incorporating them over the last 4 or 5 years.  I hesitated in buying this because I thought I knew a lot about Building Thinking Classrooms, and I am so glad I BOUGHT the book!<br><br>This book really flushes everything out in an extremely practical method. Each chapter he presents the issue from his research from REAL math classrooms, defines the problem, provides the approach that works, answers your FAQs, and summarizes the approach.<br><br>Change your classroom from students who mimic you to students who think for themselves!
