At the forefront of research in mathematics education, this new edition of Teaching Mathematics: Foundations to Middle Years continues to provide future teachers of mathematics with the information and resources they need to help them prepare for the classroom. Following an evidenced-based approach focused on identifying and reflecting on student reasoning, pre-service teachers are encouraged to develop a deep understanding of the big ideas in mathematicsand the connections between them.Now in its third edition, the text has been revised extensively, with a new structure that points more directly to the learning progressions involved in developing a deep understanding of mathematics from the early to middle years.Interspersed throughout the text are activities and thought-provoking teaching scenarios for pre-service teachers to reflect on their practice. The authors' detailed knowledge of mathematics and mathematics teaching combines effectively with the learning features to help pre-service teachers develop a deep understanding of mathematics and the teaching and learning of mathematics, which are essential to becoming confident, enthusiastic teachers of mathematics.
