Abstract

Providing labels can support categorization and relational thinking. However, little is known about how labels impact accuracy during mathematical problem solving. In one experiment, 128 fourth-graders named decimals and made true/false equivalency judgments (e.g., 0.6 = 6/10). Correct use of place value labels was related to accuracy, whereas incorrectly naming decimals as whole numbers was negatively related to accuracy. In a second experiment, we experimentally manipulated how children labeled decimals. 104 third- and fourth-graders named decimals using place value labels, informal labels reflecting everyday language, or no labels. Place value labels helped children compare equivalent decimals (e.g., 0.5 and 0.50) but had negative effects on number line estimation accuracy. Results have implications for the instructional language teachers adopt.
