This study aims to determine the ethnomathematics values contained in Sikambang art, which is the traditional art of the people of Sibolga City, North Sumatra. This research is qualitative research using an ethnographic approach. Research data collection techniques consist of observation, interviews and documentation. The collected data will be analyzed in three stages: data reduction, data submission, and verification. Next, the data will be examined based on four criteria: trustworthiness, transferability, dependability, and certainty. The results show that mathematical concepts are inherent in the culture of the people of Sibolga city, namely Sikambang art which has geometric elements, such as angles (acute, right, obtuse), lines (straight, curved, parallel, intersecting), and flat shapes (triangles, rectangles). , square, and circle). By incorporating ethnomathematics into the school curriculum, students' mathematics learning can become more contextual and meaningful. This study also helps maintain Sikambang art as a local cultural heritage that is increasingly marginalized by contemporary developments.

This research aims to determine the differences in the mathematical critical thinking abilities of students who use the 3CM learning model and students who use the direct learning model with a scientific approach, the influence of the 3CM learning model on students' mathematical critical thinking abilities and student learning activities. The type and research design used is quantitative research with a Quasi Experimental design in the form of a Nonequivalent Posttest-Only Control Design. The sampling technique used was purposive sampling. The data collection instruments were posttest mathematical critical thinking skills and observation sheets of student learning activities. Data analysis techniques in this research are normality test, homogeneity test, independent two-sample t-test, and percentage of student learning activities. The results of the research show that the mathematical critical thinking abilities of students who use the 3CM learning model are higher than students who use the direct learning model with a scientific approach, the 3CM learning model has a big influence on students' mathematical critical thinking abilities, and student activities are classified as very active after implementing the 3CM learning model.
