TI Informal Numeracy Skills: The Structure and Relations Among Numbering,
Relations, and Arithmetic Operations in Preschool
SO AMERICAN EDUCATIONAL RESEARCH JOURNAL
AB Validating the structure of informal numeracy skills is critical to
understanding the developmental trajectories of mathematics skills at
early ages; however, little research has been devoted to construct
evaluation of the Numbering, Relations, and Arithmetic Operations
domains. This study was designed to address this knowledge gap by
examining the structure of these three numeracy skill domains and
examining the relations among these domains. Three hundred ninety-three
children participated in the study (51.7% girls, 55.7% White, 33.8%
African American, and 10.5% other). Results indicated that the relations
among the informal numeracy skills were best explained by a three-factor
model that included Numbering, Relations, and Arithmetic Operations
factors, and this factor structure was the same in both younger and
older preschool children.
