Cognitive ability is one of the substantial things in learning mathematics so that textbooks which act as the main source of learning should encourage the development of students' cognitive abilities and learning goals. The aim of this research is to describe the results of the cognitive level analysis of junior high school mathematics textbooks for class VII semester I based on the revised Bloom's Taxonomy and numeracy. The type of research used is descriptive research. Data was collected by recording and coding the contents of the book which focused on example questions, Let's Practice questions and Competency Test questions. The data analysis technique uses descriptive statistics. The results of the research show that there are several existing literature studies that the cognitive level analysis of competency test questions in mathematics books must be revised so that students can understand the mechanism of questions according to the reading material regarding the contents of the book. The questions contained in textbooks do not contain a good proportion between each cognitive level, and there are still few numeracy questions involving personal, social or scientific contexts.

The quality of education in elementary schools must be well maintained so that the next generation of a nation with character is formed. One of the factors that greatly influences the quality of education in elementary schools is good leadership. The principal as the main leader in elementary schools has a very important role in managing the school and leading all members of the school. In the last few decades, transformational leadership theory has become one of the most influential leadership models in education. The transformational approach to leadership has long been considered a productive approach. Transpersonal leadership offers a more humanistic and values-centered approach to addressing the complex challenges faced by today's organizations and societies).

The research aims to develop teacher and student handbooks for realistic mathematics lessons for elementary schools. The development of this handbook is based on the reality in the field where the handbook of teachers and students especially the subjects using the 2013 curriculum still do not exist, and in daily learning activities teachers and students still use books that use themes. This research uses development research (Developmental Research). The subjects of this study were grade V students of SD Negeri 163085, H.A Bilal Tebingtinggi City and SD Negeri 106162, Medan Estate District, Deliserdang Regency. In the initial stage, observations were made during the learning process at the two schools and continued with interviews with students and teachers. From the results of these observations and interviews a primary school realistic mathematics teacher and student handbook was prepared. Furthermore, the realistic elementary school mathematics teacher and student handbook is validated by a team that aims to see and assess the quality of the realistic elementary school teacher and student mathematics handbook in order to arrange an effective handbook that will be used by teachers and students in learning. The validation results show that realistic mathematics teacher and student handbooks are developed in both categories and can be used in teaching and learning. The media book test was conducted on grade V students of SD Negeri 163085 Tebingtinggi city and SD Negeri 106162 Medan Estate Deliserdang Regency. The trial results show that the elementary school teacher and student mathematics handbook is effective and can help facilitate understanding of mathematical concepts at the elementary school level. This can be seen from the number of students who can reach the KKM from the two schools is increasing. For SD Negeri 163085 HA Bilal, Tebingtinggi City, if at the time of the pre-test only 1 student (3%) was able to reach the KKM, then after being given the learning process using a teacher and student handbook developed the number of students who could reach the KKM increased to 24 students (82.7%) while those under the KKM were only (17.3%) or 5 students. The same thing was seen in SD Negeri 106162, Medanestate Subdistrict, Deliserdang Regency. If at the time of the Pre-test only 2 students (6.6%) had scored above the KKM, after the post-test there was an increase in students who achieved the KKM score of 25 students (83.3%). An increase of 76.7% when compared to the pre test. Keywords: Handbook, teacher, student, PMR

Strengthening literacy, numeracy and character skills is an important effort to improve the quality of human resources in the Digital Age and the Era of Disruption. As a teacher or education personnel, developing students' activeness so that they can apply numeracy skills well is a big responsibility. The numeracy skills in question are number concepts and arithmetic operation skills used for daily life skills. This service activity aims to provide numeracy literacy-based learning process assistance to junior high school teachers in Medan City to improve the ability of teachers to create Numeracy Literacy HOTS questions. This activity is carried out in several stages, namely the team preparation stage, school observation, making modules/materials to be delivered to mentoring activities. In delivering the material, the community service team used various methods, questions and answers, discussions, lectures and assignments. All of these methods are used as needed. The result of the activity is that teachers can develop HOTS-based questions in groups according to their respective subjects. The group was chosen in order to provide a positive stimulus to teachers who do not know and understand the preparation of HOTS-based questions on Numeracy Literacy to be encouraged to be able to compile independently and apply in preparing evaluation questions to students.
