International research suggests that early mathematical competences predicts later mathematical outcomes. In this paper, we build on our previous study of young children's mathematical competencies (MacDonald & Carmichael, 2015) to explore the relationship between mathematical competencies at 4-5 years, as measured by teacher ratings, and…

This paper reports findings from an activity implemented in the final year of a 3-year longitudinal study of data modelling across grades 1-3.
