Questioning Zero and Negative Numbers

Virginia Wilcox 

November 2008, Volume 15, Issue 4, Page 202

Abstract:
After experiencing a Developing Mathematical Ideas (DMI) class on the construction of algebraic concepts surrounding zero and negative numbers, the author conducted an interview with a first grader to determine the youngster's existing level of understanding about these topics. Uncovering young students' existing understanding can provide focus when teachers approach new topics.
