This paper examines the relationship between early geometric skills, behavioral self-regulation skills, teacher-mother reported self-regulation skills, child age and family income in 5-6 year-old children. The participants (N = 202; 104 girls, 98 boys) average age was 71 months (sd = 4.82; Data on race/ethnicity were not asked to participants). This review found evidence that positive correlation among geometric skills, behavioral self-regulation skills, teacher-reported self-regulation skills and child age. And binary logistic regression analysis indicated that the predictors of children's likelihood of being in the above average-level early geometric skills group were their behavioral self-regulation skills (3.3% to the odds), teacher-reported self-regulation skills (3.4% to the odds) and child age (8.8% to the odds).
