Learning trajectory helps teachers to design learning. Trajectory study illustrated the flow of students in problem-solving. A model of problem-solving can be solved with manipulative media. The goal of the research is to describe the learning trajectory of students in solving the question of the type of problem solving-based manipulatives media. Manipulatives used in the study was a matchstick. The methods used in this research was descriptive qualitative. The subject of research is the student class VIIIB as much as 5 group. On the research of students was given a reserved type of problem-solving that was formed of five square, then the students solve the problem with the help of manipulative media. The results showed students solved the problem began with understanding the case (understand the problem), then the students moved and arranged it (moving), students counted many displacements of matchsticks (count the moving), then the students form a match that has been compiled into a square that was instructed in the matter of (forming). Later in the final stages of students examined whether a solution has been made right (look back). The conclusion of the research is in resolving the question of the type of manipulative media-based problem solving, and there are stages of understanding the problem, moving, count the moving, forming and look back. © IJSTR 2020.
