This service is motivated by the activities of Campus Teaching 2 which is a form of implementation of the Merdeka Learning Campus Merdeka (MBKM) program from the Ministry of Education, Culture, Research and Technology. This program is based on the ineffectiveness of the implementation of learning carried out during the Covid-19 pandemic. This can be seen from the decline in students' interest in learning, the level of understanding of students when learning, and the literacy and numeracy abilities of students. Based on these problems affect the effectiveness of the learning process, one of which is in SMP Negeri 2 Tanggulangin. One of the methods used in the service is literacy and numeracy habituation activities. The final result of this activity is the habituation of literacy and numeracy for students at SMP Negeri 2 Tanggulangin and increasing the real role and contribution of higher education institutions and students in national development

Primary students' math literacy is still inadequate. This is due to the limited number of problems based on math literacy, while studies analyzing math literacy require high-order thinking skills (HOTS). This study aims to develop instruments and analyze primary students' math literacy by reviewing high order thinking (HOTS). The study participants were 30 fifth-grade primary school students by grouping students into three HOTS levels: low, medium, and high. The study method uses a mixed-method (quantitative and qualitative) with an explanatory sequential design. The research instrument is an initial math literacy test (ML-T) that focuses on content, context, process, and level. Data analysis used descriptive statistics. The results of the study resulted in 15 ML-T which had been declared valid and reliable, divided into 6 items at levels 1-2 (easy), 5 items at levels 3-4 (enough), and 4 items at levels 5-6 (hard). The results of another study show that the success of primary students' math literacy depends on the level of ML-T problems and students' HOTS abilities. Higher ML-T levels tend to be completed with math literacy in the perspective of higher HOTS levels of students. This study's implication is to contribute to developing authentic math literacy instruments and analyzing the success of primary students' math literacy by looking at the HOTS level.
