The development of early numeracy knowledge is influenced by a number of non- mathematical factors-particularly language skills, However, much of the focus on the relation between numeracy has utilized general language measures and not domain-specific measures of mathematical language. The primary purpose of this study was to determine if the variance accounted for by general language skills in predicting numeracy performance was better accounted for by mathematical language. Further, age and education-related differences in mathematical language performance were explored. Using a sample of 136 3-to 5-year-old preschool and kindergarten children (M 4.28 years, sD 0.67 years), a series of mixed-effect regressions conducted. Results indicated that although general language performance was initially a significant predictor of numeracy performance, when both mathematical language and general language were included in the model, only mathematical significant predictor numeracy performance. Further, language was a group ference analyses revealed children from families where both parents had that than their a college performed acquired a substantial body of peers; and even by 3-years old, children have skills. Implications and future directions are discussed.
