Description
Book SynopsisThis book examines the origins and development of children''s mathematical knowledge. It contrasts the widely held view that counting is the starting point for mathematical development with an alternative comparison-of-quantities position. According to the comparison-of-quantities position, the concept of number builds upon more basic concepts of equality, inequality, and less-than and greater-than relations, which derive from comparisons between unenumerated quantities such as lengths. The concept of number combines these basic comparative concepts with the concept of a unit of measure, which allows one quantity to be described as a multiple of another. Sophian examines these alternative accounts of children''s developing mathematical knowledge in the light of research: on children''s counting; on their reasoning about continuous quantities such as length and area; on the development of the concept of unit; on additive and multiplicative reasoning; and o
Trade Review"Sophian presents a tautly reasoned and compelling challenge to schooling-as-usual, that is, to instruction that takes counting as the basis for teaching children arithmetic... She argues for highlighting the unit as the foundation of mathematics instruction [and] goes on to trace the implications of unit not only for instruction on conventional topics, such as rational number, multiplication, and division, but also for a wider mathematics education that knits number, measure, data, and geometry."—Richard Lehrer

"Sophian does a masterful job of organizing and presenting one of the major success stories of developmental and educational research – understanding the developmental roots of mathematical competence.... This book will interest and benefit both those interested in understanding children's cognitive development and those interested in developing ways of promoting mathematical competence. Sophian's research has contributed greatly to our understanding of both aspects of mathematical development; her book provides a timely and accessible introduction to the state of the art in research on children's mathematical development."
