A collaborative inservice project, Mathematics in the City, was undertaken by Catherine Fosnot and Maarten Dolk. A three-volume set describes what they learned after several years of intensive study in numerous urban classrooms. This particular volume, Young Mathematicians at Work, focuses on young children between the ages of four and eight as they construct a deep understanding of number and the operations of addition and subtraction. The authors provide a description of development, with a focus on big ideas, progressive strategies and emerging models.--Ministry of Education website.
