ABSTRACT
This research was conducted at SD Negeri Pakuncen and SD Negeri I Wonosari Kec. Pegandon Kendal in grade IV students and focuses on mathematics. The research focused on mathematics subjects because based on the results of preliminary research conducted by researchers through classroom observations and interviews with teachers it was found KKM achievement mathematics subject scores was still very low. This type of research is research development or Research and Development (R&D). R&D research is a research method used to produce certain products, and test the effectiveness of these products. Researchers developed teaching materials in the form of student pocket books with a Problem Based Learning model with ethnomathematics nuances to improve students'' critical thinking in grade IV. the pocket book model Problem Based Learning with ethnomathematics nuances is considered very valid fulfilling the suitability criteria of critical thinking teaching materials with a score of 4.25 very good, the content of teaching materials a good 4.17, presentation of teaching materials a score of 4.68 very good, the structure of presentation of teaching materials a score 3.95 is fine. The results of the development of teaching materials using the Problem Based Learning model with ethnomathematics nuances of Sunan Abinawa's grave have fulfilled the elements of practicality and effectiveness as evidenced by a score of 75.15% on observing student activities in the "good" category and a score of 81.5% on observing the implementation of learning in the "very good" category.
