"Building Thinking Classrooms in Mathematics exudes enthusiasm for students, how they think, and how those thoughts coalesce into powerful thinking classrooms. It′s also deeply practical, describing how everything from the teacher′s questions to the arrangement of the furniture can add to your students′ learning."

"If your students are not the ones doing the thinking in your classroom, then this book is for you! Peter Liljedahl provides concrete advice on each of 14 research-based practices, along with answers to frequently asked questions and suggestions for getting started, which will help you build a classroom where student thinking is the norm."

"Peter Liljedahl’s Thinking Classroom framework transformed my mathematics classroom overnight. I was frustrated that despite my best teaching efforts, some of my students still couldn’t solve simple problems by their final exam. This framework gave me a starting point that I started implementing the very next day and next steps to continue incorporating as my practice evolved. Students began to talk to each other, think through complex problems, rely less on me and more on each other and best of all had better success in the courses I taught. The Thinking Classroom framework was exactly what my students and I needed!"

"Peter refers to his research as ′mucking about,′ and that is the key thing for me, that he goes into actual classrooms, and does math with students. We learn the most from being in actual classrooms, talking to students, and figuring out how they think about mathematics tasks. We need our students to be better thinkers, and to see mathematics for what it is: a beautiful way of thinking. We need them to see that they, too, can have powerful insights into interesting mathematics problems."

"An in-depth action plan backed with significant research and data, Liljedahl’s plan is one that can improve every classroom for the better, and he foresees and addresses any questions or concerns you may have regarding implementation. It is clear Liljedahl understands the students I teach in his list of student behaviors and this book outlines methods to increase the thinking and engagement of all my students. I was able to implement many of the methods the very next day."

"Research in education that turns right around and informs our practice is invaluable in today’s schools and classrooms. Peter uses evidence gathered in mathematics classrooms to directly inform how we make changes to our teaching and learning that enhances learning. This is the essence of evidence-based practice, practice based on evidence from the very classrooms we seek to influence."

"Building Thinking Classrooms prompts us to reflect on the potential of mathematics classrooms, teachers, and learners. Supported by numerous stories from classrooms, Peter methodically exposes the familiar structures of school mathematics that suppress the potential of learners, then carefully outlines a set of opportunities around which teachers of mathematics can organize a dynamic and responsive classroom."

"This book is timely and provides an accurate portrayal of what is occurring in mathematics classroom across the country. The book is a valuable reflexive tool that teachers can use as they analyze their own teaching practices."

"Peter’s work in Building Thinking Classrooms has been the single most impactful (driver for) change in secondary mathematics education that I have witnessed. I have never seen another idea/approach/model capture so many teachers immediately, and make it past the point from learning to actual implementation in almost every classroom or instance that I have witnessed."

"For teachers hoping to transform their teaching practice, Peter has written a definitive source. Peter’s conversational style makes this work both interesting to read and easy to follow. He describes a rich set of practices that will help mathematics teachers transform, in a positive way, everything about their classroom. Peter turns the daunting challenge into something manageable with advice that is both believable and practical."

Dr. Peter Liljedahl is a Professor of Mathematics Education in the Faculty of Education at Simon Fraser University and author of the best-selling book, Building Thinking Classrooms in Mathematics (Grades K-12): 14 Teaching Practices for Enhancing Learning. Peter is a former high school mathematics teacher who has kept his research interest and activities close to the classroom. With a passion for fostering deep mathematical thinking and problem-solving skills, Peter has dedicated his career to reshaping classroom environments. His work emphasizes thinking, collaborative learning, and problem solving, leading to more effective and meaningful mathematics education experiences for students of all ages. Through his research-based innovative teaching methods, Peter continues to inspire educators worldwide to create dynamic and thought-provoking learning spaces. He consults regularly with teachers, schools, school districts, and ministries and departments of education on issues of teaching and learning, problem solving, assessment, numeracy, and building thinking classrooms. Peter has authored or co-authored 13 books, 45 book chapters, and 45 research articles on a wide range of topics including creativity in mathematics, the role of beliefs in the teaching and learning mathematics, and building thinking classrooms. He is the recipient of the Cmolik Prize for the Enhancement of Public Education (2017), The Margaret Sinclair Memorial Award Recognizing Innovation and Excellence in Mathematics Education (2018), and the Læringsprisen for Changing the way we think about Education in Denmark (2022).
