Özet: The aim of this study was to investigate the relationship between level of geometrical thinking and classification skills of polygons of 7th grade students. Relational survey model was used in this study. The sample of the study consists of 318 7th grade students from a public school in a city in Central Anatolian region. Data were collected by Geometrical Thinking Levels Determination Test, developed by Özcan (2012) and Polygon Perception and Classification Scale, developed by Ergün (2010). The obtained data were analyzed by using nonparametric tests as Kruskall Wallis-H, Mann Whitney-U and Spearman Brown correlation analysis. According to results of the study, it was found that 7th grade students’ geometrical thinking levels are mainly 1st level; more than half of the students are in the 2nd level and upper level. Students’ classification skills of polygons were at medium level. It was stated that there is a positive and meaningful relationship between classification skills of polygon and geometrical thinking levels of students. It was seen that the students with high level of geometrical thinking were successful in classifying of polygons and finding relations between polygons.
