Is there an association between frequency of Home Mathematical Activities (HMA) and Children’s Mathematical Outcomes? Data Harmonisation and Secondary Analyses of UK-based Datasets.

Early mathematical skills lay an important foundation for later academic success. Substantial variation in mathematical skills can be observed in young children and these differences have been related to family socioeconomic circumstances (SEC). The type and frequency with which parents engage in home mathematical activities (HMA’s) with their children has been suggested as a key mechanism explaining inequalities in early mathematical skills, they may also be a potential target to narrow attainment gaps. However, evidence for the relation between HMA’s and mathematical skills, and whether there is an SEC gradient in HMA engagement, remains mixed. In the present, pre-registered study, we conducted harmonisation and latent profile analyses on nine UK-based datasets (containing n= 969 dyads; mean child age= 46.83 (SD= 5.41) months; child age range 35-69 months). These analyses identified three profiles based on the frequency of engaging in HMA’s (i.e., low, intermediate, high). Children in the high HMA category had significantly higher mathematical skills than those in the intermediate and low categories. While SEC correlated with mathematical skills, no SEC differences were found in engagement with HMA’s. This suggests that families that engage in a higher frequency of HMA’s have children that tend to have higher mathematical skills, but SEC does not predict engagement with HMA’s. We discuss the implications of these findings for narrowing early attainment gaps and how to best measure and capture the home mathematical learning environment.
