Focus in High School Mathematics: Technology to Support Reasoning and Sense Making is the latest addition to NCTM’s landmark Focus in High School Mathematics series. The authors' primary interest is the potential of technology to leverage or enhance opportunities for students to engage in mathematical sense making and reasoning. Technology is an integral part of society and used extensively in most mathematics-related fields. As a result, the book focuses on technology and shows its importance in supporting reasoning and sense making.

"The thoughtful use of both action and conveyance technologies in concert can promote sense making and reasoning as a collective endeavor, engaging the classroom in community mathematical practice that builds mathematical understanding for all." — from Focus in High School Mathematics: Technology to Support Reasoning and Sense Making edited by Thomas P. Dick and Karen F. Hollebrands.

The latest addition to the landmark NCTM Focus in High School Mathematics series is now available. The book focuses on technology and, in keeping with the series’s emphasis on reasoning and sense making, it shows the importance of technology to support both reasoning and sense making. The power of recent technological tools—including computer algebra systems, dynamic geometry software, and data representation tools—has greatly enhanced reasoning and sense making in mathematics, making a volume on technology vital in the series. Technology is an integral part of society and used extensively in most mathematics-related fields. The authors’ primary interest in this book is the potential of technology to leverage or enhance opportunities for students to engage in mathematical sense making and reasoning.

The authors examine key elements of technology for mathematics teaching and the use of technology as a tool for developing understanding. Throughout the book, numerous examples demonstrate how technology can greatly enhance classroom mathematics lessons and increase students’ application of reasoning and sense making. As the authors point out, the appropriate use of technology can help students learn mathematics at a deeper level. Although technology should never be used as a replacement for basic understandings and intuitions, it can and should be used to enhance and encourage those understandings and intuitions.
