To investigate the thinking process in solving mathematical problems, the teacher can provide various kinds of questions. Questions with High Order Thinking Skills content, questions with PISA content, and so on. In this study, the researcher used an ethnomathematical nuanced question in the form of a Javanese market day which was associated with number pattern material for the 8th grade of junior high school. This research includes research and development using the stages proposed by Plomp which consists of the Premilinary research, prototyping phase, and assessment phase. The quality of the test instrument developed is known from the validity test and trial. Validity test is carried out to determine whether the test instrument is which has been developed is in accordance with the ethnomathematics concept and Polya’s problem-solving theory. Testing of the test instrument is carried out to see the level of reliability, discriminating power, and level of difficulty. Validity test is carried out by validating the test instrument developed to validators who are experts in the field of learning mathematics. Validation results the instrument shows valid results with a score of 87.87%. The test results show that the level of difficulty is medium, the discriminatory power is medium. This indicates that this instrument can be used to test mathematical problem solved.
