Being descriptive in nature, this study conducted through relational survey method. The participants of the study were total of 137 (fifth, sixth and seventh grade) students from a middle school placed in a province of northern Turkey. Among the results of the study were that the students’ skills of detecting figure pattern did not considerably affected by their grade levels. However, in the figure pattern test female students were more successful than the males. Moreover, a positively-directed strong relationship was detected among the points which students get from mathematic lesson and their achievement in the figure pattern test. Based on the observations done, the middle school students’ mistakes in the test were mostly due to their lack of attention to the questions; they mostly focused on the drawing of the figure patterns and did not think the relation between the number of figures and steps.
