Developing Mathematical Ideas (DMI): Building a System of Tens

By Deborah Schifter, Virginia Bastable, and Susan Jo Russell

Developing Mathematical Ideas is a staff development/teacher education program designed to help educators think through the major ideas of K-8 mathematics and examine how children develop those ideas. The goal is to engage teachers in a process of inquiry—nto mathematics; into learning mathematics; into students' mathematical thinking, in general, and the thinking of one's own students, in particular. In a DMI seminar, teachers discuss print and video cases, explore mathematical questions, investigate the mathematical thinking of their own students, analyze lessons from innovative curricula, and read and discuss essays about related research.

In this module, participants explore the base-ten structure of the number system, consider how that structure is exploited in multi-digit computational procedures, and examine how basic concepts of whole numbers reappear when working with decimals.
