This study aimed to develop “Evaluation Instrument for the Early Mathematical Reasoning Skills” in order to determine the mathematical reasoning skills of children in the area of measurement and data analysis-probability as well as to perform its validity and reliability. Furthermore, variables such as the effect of child gender, age, institution attended and part/full time attendance to the institution, total duration of preschool attendance as well as age and educational background of their parents were analyzed. The study group is composed of randomly selected 204 children of normal development in Ankara at the age of 60-74 months attending dependent and independent kindergarten, private preschools, daycare centers and kindergartens of Ministry of National Education. Data were collected using “Evaluation Instrument for the Early Mathematical Reasoning Skills” that is type of holistic rubric and “Child Information Form” that was developed by the researcher. The instrument developed was found to be reliable and valid. No significant difference was found between the scores of reasoning areas and types of boys and girls. In addition, there was no significant difference between the scores of age of parents and total duration of preschool attendance for the reasoning areas and types. Older children gained higher scores from the instrument than attendees of preschool and those attended institutions part-time for the measurement and induction areas. It is observed that children of university graduate fathers got higher scores as for the measurement and induction areas; while, those of university graduate mothers had higher scores from the data analysis-probability and induction areas. Moreover, no difference was found among the variables for the deduction reasoning scores.
