This K—8 methods text clearly links the teaching theories and techniques it proscribes to the most current NCTM Principles and Standards for School Mathematics. Based on the premise that mathematics teaching should be child-centered and constructivist, this text explains what children's math thinking might be developmentally and then models typical problems for concept building. Beginning with the problem solving chapter and followed up in subsequent content chapters, this edition provides over 200 activities that can serve future teachers as classroom resources.
