Take Your Professional Development to a New Level of Excellence
Whether you're a teacher, a coach, a department chair, or a school or district administrator, Developing Mathematical Ideas (DMI) will enable you to deliver rich and rewarding seminars to support teacher understanding and student learning.
Number and Operations, Part 1: Building a System of Tens: Calculating with Whole Numbers and Decimals
The first module in the seven-part DMI Series, this title engages participants in a collaborative learning experience. The thirty cases provide the basis of each session's investigation of specific mathematical concepts and teaching strategies.
The
online facilitator's package
contains everything necessary to prepare for and lead the seminar, including access to the casebook content and classroom videos.
The
casebook
is the key resource for participants and is meant to be read and discussed under the guidance of the facilitator.
Number and Operations, Part 2: Making Meaning for Operations: In the Domains of Whole Numbers and Fractions
The second module in the seven-part DMI Series, this title concentrates on the kinds of actions and situations that are modeled by addition, subtraction, multiplication, and division and how students come to understand them. Participants investigate the four basic operations on whole numbers, and then move to a study of the operations in the context of fractions.

Geometry, Part 3: Measuring Space in One, Two, and Three Dimensions
Third in the seven-part DMI Series, this title explores the conceptual bases of measurement and how children develop their understanding of these ideas. Participants examine different attributes of size, develop facility in composing and decomposing shapes, and apply these skills to make sense of formulas for area and volume.
