Abstract
This study was purposed to describe questions that used to measure mathematical thinking aspect modelling in topic linear equation system of two variables for junior high school students. Mathematical Thinking aspect modelling has 4 indicators, which are: concretization, objectification, mathematical sense-making, and estimation of results. The subjects of this study were 3 junior high school students grade 8. This study was design research which is consisting: Preliminary design, FGD, trial, interview, and retrospective analysis. The data analysis that used in this study was qualitative. As the result of this study, for questions in topic number 1, student 1 showed the appearance of 3 indicators (concretization, objectification, mathematical sense-making), students 2 and 3 could not answer the question. For question number 2 all students could not answer the question. For question number 3, all of 3 students could answer correctly, all of them also showed 3 indicators (concretization, objectification, mathematical sense-making). Because of that, need to do correction in question number 2.
