Chapter 13: Learning about Fractions as Points on a Number Line. Geoffrey Saxe, Meghan Shaughnessy, Ann Shannon, Jennifer Langer-Osuna, Maryl Gearhart (all of University of California – Berkeley) and Ryan Chinn (Willard Middle School, Berkeley, California) exploit the potential that number lines have for supporting students’ understanding of fractions in the upper elementary and middle school grades. Their research interweaves developmental studies of children’s understandings of fractions with classroom studies on students’ learning and the pedagogical strategies that support their learning.
