Critical thinking skills in Mathematics learning are commonly only centred on typical students. Sometimes teachers forget that there are students with special needs who also need to study Mathematics; one of them are students with Asperger's Syndrome. Through this study, the researcher used the Montessori method to teach the plane geometry topic. The research method used was descriptive qualitative. The students observed were two students with Asperger's learning while applying the Montessori method. This study illustrated how the Montessori method was used to students with Asperger's syndrome and described the profile of students critical thinking suffering from Asperger's syndrome. The instruments in this study were the critical thinking test and field notes conducted by the research team. The results showed that the Montessori method seemed to make students with Asperger's Syndrome more expressive and willing to interact with the surrounding environment. They also had better motor skills and the critical thinking skills of the students were of high criteria.
