<![CDATA[The low level of mathematics learning outcomes among elementary school students remains a challenge, particularly in answering questions that require critical thinking skills, such as analyzing, evaluating, and interpreting information. This study aims to determine the relationship between critical thinking skills and mathematics learning outcomes among fourth-grade elementary school students. The study was conducted at SDN Cikeas 05, Bogor Regency. This study employed a quantitative approach with a correlational research design. The population consisted of all fourth-grade elementary school students in Cikeas, Bogor Regency. The sample was SDN Cikeas 05, selected through cluster sampling, with 30 students from Class IV B serving as the research subjects. Data on critical thinking skills were collected using an essay test instrument, while data on mathematics learning outcomes were obtained from students’ first-semester report card records for the 2025/2026 academic year. Data were analyzed using descriptive and inferential statistics through the Pearson Product Moment correlation test, t-test, and coefficient of determination test. The results revealed a positive and significant relationship between critical thinking skills and mathematics learning outcomes, with a correlation coefficient of 0.543, which was categorized as moderate. These findings indicate that higher critical thinking skills are associated with higher mathematics learning outcomes. In addition, critical thinking skills contributed 29.5% to students’ mathematics learning outcomes. The findings imply that teachers need to implement learning activities that foster students’ critical thinking skills in order to improve mathematics learning outcomes.]]>
