To Investigate Mathematical Cognitive Abilities (Spatial and Numerous) and Their CorrelationWith Educational Development, Mental Age and Gender

This research was carried out in order to evaluate understanding of fundamental mathematical concepts and the relation between cognitive mathematical abilities and performance of male and female elementary school students in Mazandaran based on Piaget’s theory. To fully objectives of this research hypotheses have been studied of which the first deal with those in Piaget’s studies. Population in this research comprises all male and female elementary school students in academic year in Mazandaran which has been selected trough accidental clustering sampling. First, four cities have been chosen then to elementary schools and finally testes (male, female) from each school have been selected the population has undergone Piaget’s mathematical recognition test and finally students have been selected from each grade the instruments utilized in this study are Piaget’s test Goodenough’s test, the grand mean of all lessons in the previous semester. Findings indicates that there is significant difference in Performance of students in 5 elementary grades in mathematical concepts abilities. There is significant difference between in elementary grades in spatial perception of point, concept of multiply and fraction, but there is not significant difference in other abilities. There is relation between cognitive mathematical abilities and difference elementary grade students. There is not relation between cognitive mathematical abilities and mental age. There is not significant difference between males and females mathematical concepts abilities. (P<)
