The project adapted and studied a promising and replicable teacher professional development (PD) intervention, called Collaborative Math (CM), for use in early childhood programs. CM content focused on nine topics emphasized in preschool mathematics, including sets, number sense, counting, number operations, pattern, measurement, data analysis, spatial relationships, and shape. Through several phases of development and research, the project investigated the contributions of project components on increases in teacher knowledge and classroom practices, student math knowledge, and overall implementation. The project reached approximately 200 Head Start (HS) teaching staff, better preparing them to provide quality early math experiences to more than 3,000 HS children during the project period.
