Number Sense

Abstract

We describe the concept of number sense, an analog as important to mathematics learning as phonemic awareness has been to the reading research field. Understanding the concept of number sense and relevant research from cognitive science can help the research community pull together fragmented pieces of earlier knowledge to yield a much richer, more subtle, and more effective means of improving instructional practice. This article demonstrates how the number sense concept can offer a useful framework for conceptualizing interventions that will significantly enhance mathematics instruction for students with mathematical disabilities.
