Features and Benefits

Each DMI Seminar models how math instruction should be delivered through practical examples teachers can follow in their own classroom.

Casebook
Each seminar is built around a casebook containing 25 to 30 classroom cases that include ideas expressed by students and teachers in their own words. These cases are grouped into seven chapters which track a particular mathematical theme from kindergarten through grade eight.

Facilitator's Guide

This component is the implementation tool for the DMI seminars. It contains detailed agendas for each sessions and "Maxine's Journal" which details one facilitator's seminar experience. The Facilitator's Guide is designed to help facilitators identify particular strategies useful in leading case discussions, plan seminar activities, understand major ideas to be explored in each session, and think through issues of teacher change

Overview

The Developing Mathematical Ideas (DMI) Professional Development Series is practical, accessible, and non-intimidating. Each module features a Casebook of actual lessons, a real-time video of classroom clips, and a Facilitator’s Guide. Together the materials model how math instruction should be delivered and provides teachers with practical examples that they can follow in their own classrooms. Building their own understanding of math concepts and witnessing “how to teach” math will increase teachers’ comfort level and lead to greater achievement among students.

Use DMI to build an in-depth and effective professional development program that will help teachers of elementary and middle school math to:

  • Deepen their own understanding of math concepts
  • Define and select mathematical objectives for students
  • Learn how to support students’ mathematical thinking
  • Understand the power and complexity of student thinking
  • Recognize the key mathematical ideas with which students struggle
  • Ask questions that enhance learning
  • Identify mathematical connections to promote understanding
  • Build the strong foundation for Algebra that is critical for future math success
