 Developmental predictors of fraction concepts and proceduresNancy C Jordan
School of Education, University of Delaware, Newark, DE 19716, USA
J Exp Child Psychol 116:4558. 2013..The results suggest that although there is considerable shared variance among the predictors, both general and numberrelated competencies are uniquely important for explaining why some children struggle with fractions...  Early math matters: kindergarten number competence and later mathematics outcomesNancy C Jordan
School of Education, University of Delaware, Newark, DE 19716, USA
Dev Psychol 45:85067. 2009..The findings show the importance of early number competence for setting children's learning trajectories in elementary school mathematics...  Socioeconomic variation, number competence, and mathematics learning difficulties in young childrenNancy C Jordan
School of Education, University of Delaware, Newark, Delaware 19716, USA
Dev Disabil Res Rev 15:608. 2009..Weaknesses in number competence can be reliably identified in early childhood, and there is good evidence that most children have the capacity to develop number competence that lays the foundation for later learning...  Development of number combination skill in the early school years: when do fingers help?Nancy C Jordan
School of Education, University of Delaware, Newark, DE 19716, USA
Dev Sci 11:6628. 2008..The findings indicate that finger use is most adaptive when children are first learning number combinations, but this benefit lessens over time...  A longitudinal study of mathematical competencies in children with specific mathematics difficulties versus children with comorbid mathematics and reading difficultiesNancy C Jordan
School of Education, University of Delaware, Newark 19716, USA
Child Dev 74:83450. 2003..The NA and RD only groups performed better than the MDRD group in most areas. Deficiencies in fact mastery and calculation fluency, in particular, are defining features of MD, with or without RD...  Number sense growth in kindergarten: a longitudinal investigation of children at risk for mathematics difficultiesNancy C Jordan
University of Delaware, Newark, USA
Child Dev 77:15375. 2006..Using growth mixture modeling, 3 classes of growth trajectories in number sense emerged...  Mathematical thinking in secondgrade children with different forms of LDN C Jordan
University of Delaware, School of Education, Newark 19716, USA
J Learn Disabil 33:56778. 2000....  Arithmetic fact mastery in young children: a longitudinal investigationNancy C Jordan
School of Education, University of Delaware, Newark, DE 19716 2922, USA
J Exp Child Psychol 85:10319. 2003..Deficits in fact mastery are highly persistent and appear to be independent of reading and language abilities...  Using kindergarten number sense to predict calculation fluency in second gradeMaria N Locuniak
University of Delaware, Newark, USA
J Learn Disabil 41:4519. 2008..The relation of early number skills to later calculation fluency has important implications for math screening and intervention...  Early identification and interventions for students with mathematics difficultiesRussell Gersten
College for Education, University of Oregon, USA
J Learn Disabil 38:293304. 2005..These are discussed in terms of the components of number sense. Implications for early intervention strategies are explored...

 Developing Number Sense in Children at Risk for Mathematics Learning DisabilitiesNancy C Jordan; Fiscal Year: 2010..Age, gender, attention, language, working memory, and nonverbal IQ will be entered as covariates in the analyses. The primary analytic strategy will be growth curve modeling, a special case of hierarchical linear modeling. ..
 A Developmental Study of Mathemetics Disabilities 2NANCY JORDAN; Fiscal Year: 2007..We also expect the findings to have direct applications for the development of evidencebased math interventions. ..
 DEVELOPMENTAL STUDY OF MATHEMATICS DISABILITIESNANCY JORDAN; Fiscal Year: 2001..Such data should provide an empirical basis for developing diagnostic tools for identification of mathematics abilities. ..
