Discusses the history of different methods of representing numbers and how these representations facilitated counting and computing devices such as the abacus. (MDH)

Discusses the efforts of one Japanese company that makes abaci to demonstrate that the abacus continues to be a feasible alternative as a calculator in the elementary school mathematics curriculum. Argues that the abacus improves number sense, mental computation, and mathematics achievement for students who use the abacus. (MDH)

This book, written by participants of a joint Japan-United States seminar, drawing upon years of classroom and research experience, examines how computation applies in basic and far-reaching ways, starting in early childhood and continuing throughout individuals' lives. The book presents both the Japanese and American views of computational…
