Early Childhood Mathematics Education Research: Learning Trajectories for Young Children (Studies in Mathematical Thinking and Learning)
"Sarama and Clements’ landmark book provides a comprehensive review of psychological and educational research leading to new insights into young children’s mathematical learning and how it can be fostered.  The authors’ "learning trajectories" approach blends a research-based appreciation of the developing child’s mathematical mind with practical educational goals and methods.  The book is essential reading for all those with a deep interest in promoting an effective and enriched approach to early childhood mathematics education."-- Herbert P.
