<![CDATA[This research aims to see the influence of ethnomathematics through various Pattern of Batik Betawi on the Numerization Literacy Ability of class IV students on flat shapes learning material. This research was conducted at SDN Cipinang Besar Selatan 20 Pagi with a sample of fourth grade students in the second semester of the 2023/2024 school year. Samples were taken using the Single-Stage Cluster Sampling technique. The method used is a quasi-experimental research method with a pretest-posttest control group design research design. The data was collected using an instrument in the form of descriptions that have been theoretically and empirically validated. The results of the research analysis showed that the average pre-test result for the experimental class was 6.73 and the post-test was 8.50 which its show a bigger increase of 1.77 points in the experimental class that applied an ethnomathematics approach rather than the control class that applied conventional learning. Therefore, the alternative hypothesis can be accepted and it can be concluded that the application of Ethnomathematics through various pattern of batik Betawi has a positive effect and able to improve students' numerization literacy skills.]]>
