—Thomas P. Carpenter This highly anticipated follow-up volume to the landmark addresses the urgent need to help teachers understand and teach fraction concepts.   Fractions remain one of the key stumbling blocks in math education, and here Empson and Levi lay a foundation for understanding fractions and decimals in ways that build conceptual learning.  They show how the same kinds of intuitive knowledge and sense making that provides the basis for children’s learning of whole number arithmetic can be extended to fractions and decimals.  Just as they did in and Empson and Levi provide important insights into children’s thinking and alternative approaches to solving problems. Three themes appear throughout the book: With illuminating examples of student work, classroom vignettes, “Teacher Commentaries” from the field, sample problems and instructional guides provided in each chapter, you’ll have all the tools you need to teach fractions and decimals with understanding and confidence.
