<![CDATA[This study aims to describe students' critical thinking and mathematical communication skills Algebra material TIMSS type of question. This type of research is descriptive qualitative. The subjects were taken by 3 students each with high, medium and low math abilities in class VIII of SMPN 1 Jepara 2021/2022. Data was collected by means of critical thinking tests, mathematical communication, interviews and documentation. The data analysis technique was carried out in 3 stages, namely data reduction, data presentation and conclusion drawing. The technique of checking the validity of the data is using the triangulation method. Critical thinking analysis, 1 student with high mathematical ability who fulfills all indicators while the other 2 students only meet 2 critical thinking indicators. Students with moderate mathematical ability 3 students who are only able to fulfill 1 indicator of critical thinking. Students with low mathematical abilities, 1 student who is only able to fulfill 1 indicator while the other 2 students are not able to fulfill all critical thinking indicators. For mathematical communication, students with high mathematical ability met 5 indicators of mathematical communication, 2 students with moderate mathematical ability met 3 indicators but the indicators achieved were different while 1 other student met 4 indicators of mathematical communication. 2 students with low mathematical ability met 1 indicator and 1 other student was not able to fulfill all mathematical communication indicators.]]>
