Conclusions 189Acknowledgments 192References 192AbstractChildren from low-income families begin school with less ma<strong>the</strong>maticalknowledge than peers from middle-income backgrounds. This discrepancyhas long-term consequences: Children who start behind usually staybehind. Effective interventions have <strong>the</strong>refore been sought to improve <strong>the</strong>ma<strong>the</strong>matical knowledge <strong>of</strong> preschoolers from impoverished backgrounds.Some curriculum-based interventions have met with impressive success;two disadvantages <strong>of</strong> such interventions, however, are that <strong>the</strong>y are quitecostly in terms <strong>of</strong> <strong>the</strong> time <strong>and</strong> resources <strong>the</strong>y require <strong>and</strong> <strong>the</strong>ir multifacetedlessons make it impossible to determine why <strong>the</strong>y work. In this chapter, wedescribe a <strong>the</strong>oretical analysis that motivated <strong>the</strong> development <strong>of</strong> a simple,brief, <strong>and</strong> inexpensive intervention that involved playing a linear numberboard game. Roughly an hour <strong>of</strong> playing this game produced improvementsin numerical magnitude comparison, number line estimation, counting,numeral identification, <strong>and</strong> ability to learn novel arithmetic problems bypreschoolers from low-income backgrounds. The gains were greater thanthose produced by playing a parallel nonnumerical game or engaging inPsychology<strong>of</strong> Learning<strong>and</strong> Motivation, Volume 55ISSN 0079-7421, DOI 10.1016/B978-0-12-387691-1.X0001-4# 2011 Elsevier Inc.All rights reserved.171
