In this article from The Wall Street Journal, Sue Shellenbarger explains changes in teaching fractions that have been shown through research to improve students' overall understanding of fractions. The article is based on research from University of Delaware, Vanderbilt University, and Carnegie Mellon University. The article also reflects shifts in the Common Core State Standards: earlier introduction of fractions and more conceptual understanding. Included in the article is a seven and a half minute audio interview with Sue Shellenbarger on The Wall Street Journal This Morning.

Teachers can use this interactive tool to help students build a conceptual understanding of the value of fractions by placing numbers, visual models, and decimals on a number line. Students learn that every fraction and decimal describes a specific value. This page includes a video demonstration of the tool and sample lessons from the Conceptua curriculum. Free registration is required to use the tool. A paid subscription is necessary to access full curriculum and allow full student use.
