ab: Summary: The authors of this article collaborated with fourth-grade
teachers from two schools to support implementation of a research-based
fraction and decimal curriculum (Rational Number Project: Fraction
Operations and Initial Decimal Ideas). Through this study, they
identified five indicators of rich conceptual understanding of
decimals, which are described in this article. They then show how these
indicators comprise a framework for monitoring student learning and
guiding instruction. (ERIC)
