This study is design research aimed to describe about mathematical thinking question that can be used to measure aspect representation in topic number of pattern. The subjects of this study are three students in grade 8 and 9. The process of this study consists of five stages, namely: preliminary design, focus group discussions, trials, observation and interview, and retrospective analysis. The data analysis was qualitative technique. As the results of this study, for question number 1, all of student-s answer was correct, student 1 showed appearance of numeric representation and visual representation, student 2 showed appearance of numeric representation, student 3 showed appearance of visual representation. For question number 2, student 1-s answer was correct which also showed appearance of numeric representation and visual representation, student 2 showed appearance of visual representation and numeric representation but it-s not correct, student 3 showed appearance of visual representation but it-s not correct. For question number 3, all of student-s answer was correct, student 1 showed appearance of visual representation, numeric representation, symbolic representation and algebraic representation, student 2 showed appearance of symbolic representation and algebraic representation, student 3 showed appearance of visual representation.
