Introduction The aim of this study was to determine the role of meta-cognition and verbal ability in prediction of the mathematical performance of preschool children. Materials and Methods This study was descriptive and correlational. Based on Morgan table band cluster sampling method, a sample of 196 preschool children were selected from preschool children in Ilkhechi during 2016-2017. The mathematical performance, metacognition test Salonen and verbal ability test were performed. Results The results revealed a significant positive relationship between meta-cognition and verbal ability with mathematical performance in preschool children. Results of multiple regression analysis showed that metacognition and verbal abilities are capable to predict mathematical performance of preschool children. Conclusion Meta-cognitive and verbal ability can be used to improve the mathematical performance of children.
