Measuring the World Overview
http://www.daviddennis.info/MtWindex.html
Is a textbook for a mathematics course for future elementary and middle school teachers, written by Susan Addington and David Dennis. The book is a unified course of study based on a foundation of measurement concepts and practices. This book is based on the most recent research in mathematical cognition, especially on multiplicative thinking, measurement, and neuroscience. See References for some fairly nontechnical reading. Technology is the elephant in the room of contemporary math education. The ...
