The learning that has been carried out so far in the school tends to apply classical learning techniques that do not pay attention to the stages in the variety of learning. For this reason, a good way is needed to learn a lesson, one of which is known as a learning technique. In this research activity, the theme of mathematics learning for school children is based on the KUMON method. This technique is considered one of the solutions that is expected to increase children's academic values and awareness in learning and train children to have independence and full responsibility in the learning process. Indirectly, when repeating the material done by the child, the child will get a reinforcement value that is more than the material conveyed Repetition is intended to provide added value in learning a new material and is implicit in the hierarchical structure of the material that has been learned so that it will be self-absorbed when the child is faced with a problem that establishes a relationship to relates the past material to the future material. the regression analysis test using simple linear regression analysis with the general form of the equation formed is as follows: Y = 0.099X + 36.823. Where the learning variable affects the bound variable of learning outcomes of 0.099 and the value of the constant when no one variable influences, it will produce a learning outcome value of 36, 823. hypothesis test proved to be accepted and the null hypothesis was rejected from the results of the calculation of the value of t obtained was t calculated 6.796 greater than t tabel = 0.697 and sig = 0.763 > sig 0.05, it can be proven that the learning variable has a positive and significant effect on the learning outcome variable.

This study aims to improve students' mathematics learning outcomes through the implementation of cooperative learning model using the Think Pair Share (TPS) technique. The subjects of the study were the students of class VII-A at SMPN 3 Surabaya. This Classroom Action Research (CAR) was conducted in two cycles, each consisting of planning, implementation, observation, and reflection stages. Data were collected through tests, namely formative tests and post-tests. The results showed a significant improvement in students' mathematics learning outcomes after the application of the Think Pair Share technique. In the first cycle, the average student scores increased significantly compared to before the intervention, with even greater improvements observed in the second cycle. Besides improving learning outcomes, the application of the Think Pair Share technique also had a positive impact on student participation and interaction during the learning process. Students became more active in discussions and helped each other understand the lesson material. Therefore, the Think Pair Share technique has proven effective in enhancing the mathematics learning outcomes of students in class VII-A at SMPN 3 Surabaya. .

Universities' development hinges significantly on student admissions, necessitating accurate predictions for effective planning. This study applies the Monte Carlo simulation method to forecast new student arrivals at the Faculty of Mathematics and Natural Sciences (FMIPA) at Universitas Negeri Medan (UNIMED). Utilizing data from 2021 to 2023 sourced from the PDDikti website, the research employs PHP programming for implementation. The Monte Carlo algorithm's numerical prowess ensures precise statistical data simulation, comprising data collection, probabilistic distribution computations, cumulative distribution determinations, random number generation, and simulation analyses. Simulation results for 2022, 2023, and 2024 exhibit consistent trends, projecting an average of 860 to 930 new students per program. This methodology surpasses manual estimations, offering robust insights for university resource allocation and strategic management. Despite its effectiveness, study limitations, such as model assumptions, warrant continuous validation with actual data. This research advances predictive modeling in higher education, providing a foundation for future enhancements and comprehensive prediction integrations.

This research aims to not only make students skilled in mathematics but also provide provisions for its application in everyday life. Mathematics learning needs to use concrete objects to help students understand mathematical concepts according to the stage of student learning development, namely at the concrete operational stage. Addition and subtraction of numbers is one of the subjects of mathematics. Students often have difficulty learning addition material using saving techniques and subtraction using borrowing techniques. The use of learning media in the form of concrete objects is very helpful in learning the material of adding and subtracting numbers. One of the learning media that can be used is the decanomial bead bar box. This media is a Montessori-based media. This research aims to describe the implementation of decanomial bead bar box media for addition and subtraction of numbers in class II students at SDN Jati 03 and to describe student learning outcomes in the implementation of decanomial bead bar box media for addition and subtraction of numbers in class II students at SDN Jati 03.
