Number and Operations, Part 2: Making Meaning for Operations Casebook

The Making Meaning for Operations Casebook was developed as the key resource for participants Developing Mathematical Ideas seminar experience. The twenty-nine cases, written by teachers describing real situations and actual student thinking in their classrooms, provide the basis of each session s investigation of specific mathematical concepts and teaching strategies. By reading and discussing the cases under the guidance of the facilitator, participants are actively engaged in their own learning enterprise and will learn to recognize the key mathematical ideas with which their students are grappling; consider the types of classroom settings and teaching strategies that support the development of student understanding; become aware of how core mathematical ideas develop across the grades; work on mathematical concepts and gain better understanding of mathematical content; and discover how to continue learning about children and mathematics. The casebook is composed of eight chapters: the first seven consist of classroom cases from kindergarten through grade 7; chapter 8 is an essay providing an overview of the research related to the situations described in the first seven chapters. The chapters are as follows: Chapter 1 Making meaning for whole number addition and subtraction Chapter 2 Making meaning for multiplication and division Chapter 3 When dividing doesn't come out evenly Chapter 4 Greater than, less than, equal to Chapter 5 Combining shares, or adding fractions Chapter 6 Taking portions of portions, or multiplying fractions Chapter 7 Expanding ideas about division in the context of fractions Chapter 8 Highlights of related research
