With a focus on growing as a teacher, Young Children and Mathematics: Teaching and Learning, shows future and current early childhood educators the reasons why math is so important for young children. It includes ways to build on the skills most early childhood educators have such as creating rich environments, using children’s literature and encouraging play to build math understandings. There is a focus on essential topics and encouragement to use learning trajectories to help students develop those understandings. Last, there is a chapter on making peace with never having the perfect lesson and how to strive to be a better teacher through reflection and collaboration.
