The purpose of this study is to see if there is any difference in the cognitive load of fifth graders according to the type of mathematical patterns in the task of finding regularity of patterns. To do this, the process of finding regularity solutions for 35 fifth grade students was recorded by using an eye-tracker and the correct response rate, self survey and the total visit duration were analyzed. As a result, there were no significant differences in representation patterns. The pattern of ‘growth·deformation method of creation’ and ‘geometric property’ were generated the lowest accuracy ratio, the highest cognitive load survey result, and the longest total visit duration. Based on these results, for learning of various types of pattern, it is considered appropriate to apply patterns of numbers and picture expression together from the beginning. And cognitive loads of ‘growth·deformation’ and ‘geometrical properties’ is judged to be greater than other generation methods and properties of pattern. So it is considered appropriate to apply 'repeat pattern' and 'physical, relational pattern‘ at the beginning of pattern learning and 'growth·deformation pattern' and ‘geometrical property pattern' are needed to handle later in pattern learning.
