Invigorate instruction and engage students with this treasure trove of "Great Ideas" compiled by two of the greatest minds in mathematics. From commonly taught topics in algebra, geometry, trigonometry and statistics, to more advanced explorations into indirect proofs, binomial theorem, irrationality, relativity and more, this guide outlines actual equations and techniques that will inspire veteran and new educators alike.
This updated second edition offers more proven practices for bringing math concepts to life in the classroom, including
114 innovative strategies organized by subject area
User-friendly content identifying "objective," "materials," and "procedure" for each technique
A range of teaching models, including hands-on and computer-based methods
Specific and straightforward examples with step-by-step lessons
Written by two distinguished leaders in the field-mathematician, author, professor, university dean and popular commentator Alfred S. Posamentier, along with mathematical pioneer and Nobel Prize recipient Herbert A. Hauptman-this guide brings a refreshing perspective to secondary math instruction to spark renewed interest and success among students and teachers.
Alfred S. Posamentier is professor of mathematics education and dean of the School of Education at the City College of the City University of New York. He has authored and co-authored several resource books in mathematics education for Corwin Press. Herbert A. Hauptman is a world-renowned mathematician who pioneered and developed a mathematical method that has changed the whole field of chemistry. For this work he was recipient of the 1985 Nobel Price in chemistry. With this book Dr. Hauptman brings his highly sophisticated knowledge of mathematics and his many years of exploration in higher mathematics to the advantage of secondary school audience.
