The Teaching Math to Young Children practice guide presents five recommendations designed to capitalize on children's natural interest in math to make their preschool and school experience more engaging and beneficial. These recommendations are based on the panel members' expertise and experience and on a systematic review of the available literature. The first two recommendations identify which early math content areas (number and operations, geometry, patterns, measurement, and data analysis) should be a part of the preschool, prekindergarten, and kindergarten curricula, while the last three recommendations discuss strategies for incorporating this math content in classrooms. The recommendations in this guide can be implemented using a range of resources, including existing curricula. (author abstract)
