This study investigated the genetic and environmental sources of individual differences in estimation of numerical magnitudes on a number line task, and of the covariation between number line estimation and mathematics measures of fluency and problem‐solving. It further explored genetic and environmental contribution to sex differences in estimation of numerical magnitudes and in mathematics.
