Fraction Study Project Description
Knowledge of rational numbers is essential for mathematical achievement (Siegler, Thompson, & Schneider, 2011; Torbeyns, Schneider, Xin, & Siegler, 2015) and, in turn, for access to STEM disciplines and careers. This project intends to facilitate such access for urban, low-income students by investigating the affordances and obstacles of ‘fractions-of-quantity’ as a cognitive vehicle to extend second-grade students’ number sense of fractions. Focusing on conceptual understandings of fraction magnitude (equivalence, inequality, and order), a collaborative team composed of two teachers from the Newark Public Schools, their mathematics supervisor, and a university mathematics educator are designing tasks and, in two afterschool classrooms, working with 30 students on the tasks to understand how to increase students’ fraction sense. The afterschool classrooms and students are located at the 13th Avenue/Dr. MLK, Jr. School. The expected outcome is that students become conversant with fraction magnitude and view fractions as a multiplicative comparison between two commensurable quantities. In previous investigation (Empson, Junk, Dominguez, & Turner, 2005), researchers have underscored this view as critical for students’ successful acquisition of fraction knowledge.
