This study aims to describe the students' thinking process in solving TIMSS math problem on measurement of angle in geometric shapes based on Polya’s problem solving step associated with Swartz’s thinking process theory. The subject of the research was a grade VIII student in SMP Negeri 4 Malang who was classified as intelligent but made many mistakes when completing the test. Data collection methods used were test and interview methods. The results show that students go through the step of generating ideas, clarifying ideas, assessing the reasonableness of ideas, and thinking complex on every step of problem solving, but at the look back step, students do not clarify the idea.
