This research evaluated an interactive, story- and game-based measure of preschool mathematical development. The hypothesis was that 9 measurable variables—quantification, counting, set comparison, numerals, number line, positional terms, shapes, addition/subtraction, and patterning—would make a significant contribution to the latent construct of mathematical development. CFA indicated good model fit: chi square(24,N=118)=24.283, p=.446; NFI=.968; CFI=1.000; and RMSEA=.010. All standardized path coefficients demonstrated both statistical and practical significance: regression weights ranged from .562 to .894. The results indicate that the measurement tool is a valid and reliable measure of mathematical development for this sample. Conferees will be able to view a child’s assessment via laptop and discuss the developmental trajectories and statistical validation, as presented on the poster, with the researcher.
