Abstract

Adaptivity with arithmetic can be seen as one aspect of arithmetic competences that may account for important variation in algebra attainment. The present study aims to presents evidence for the existence and relevance of a newly acknowledged component of adaptivity with arithmetic, namely, adaptive number knowledge. In this study, 1065 Finnish primary school students completed measures of adaptive number knowledge, arithmetic conceptual knowledge, and arithmetic fluency. Three months later they completed a measure of pre-algebra skills. Individual differences in adaptive number knowledge were identified using latent profile analysis. The identified profiles predicted later pre-algebra skills. These results suggest that adaptive number knowledge is a relevant component of mathematical development, and may help account for disparities in algebra development.
