Making sense

"Making Sense presents the best current research-based ideas on how to design classrooms that help students learn mathematics with understanding. It is based on the authors' work in four separate research programs, all of which investigated the effects of specific instructional approaches. Out of their ongoing discussions emerged a striking consensus about what features are essential and what features are optional, information they share in this book. They also provide glimpses into their individual projects and into the classrooms from which they have drawn many of their ideas."--BOOK JACKET.
