Abstract
Problem solving is one of the abilities that is essential in mathematics learning. Students who have the skill can solve an uncommon problem by using mathematical models and prove the exact of the results obtained. This research aims to analyze the problem solving steps of HOTS problems according to Polya which can be achieved by junior high school students. This research was designed in descriptive qualitative that involved 30 students consisting of three levels: high, medium and low level students. Data were collected by using HOTS problem test and an interview. The results showed that the high level students are capable to solve the problem but have not been able to prove the exact of the results, the medium level students are capable to reach the steps of making mathematical models, while the low level students are not capable to make mathematical models.
