'The presentations gathered in this book offer plenty of ideas and advice for anyone seeking to start a program or affiliate with an existing one. In general, the authors do not compare their programs to those described in other chapters, but readers of the whole volume will identify significant commonalties across the various audiences, processes, obstacles, and outcomes described.Summing up: Recommended. All readers.'CHOICEThis groundbreaking anthology is a collection of accounts from leaders in mathematical outreach initiatives. The experiences range from prison education programs to alternative urban and Indian reservation classrooms across the United States, traversing the planet from the Americas to Africa, Asia, and the Indian subcontinent. Their common theme is the need to share meaningful and beautiful mathematics with disenfranchised communities across the globe.Through these stories, the authors share their educational philosophy, personal experiences, and student outcomes. They incorporate anecdotal vignettes since research articles in mathematics education often exclude them. The inclusion of these stories is an element that adds immeasurable value to the larger narratives they tell.
