This study aims to improve the numeracy literacy skills of elementary school students through a game-based learning media approach. The background is the low numeracy literacy skills of Indonesian students compared to other countries, as shown by the results of the PISA and TIMSS tests. Many elementary school students still have difficulties in reading, understanding, and applying numerical information and basic mathematics in everyday life. The research method used is systematic literature review by analyzing journals related to improving numeracy literacy skills through game-based learning media. The results of the review show that the use of game-based learning media can effectively improve the numeracy literacy skills of elementary school students. Game-based learning is able to make math learning more interesting, interactive, and increase student motivation. The implication of this research is the importance of developing and implementing game-based learning media to improve students' numeracy literacy skills in elementary schools.

This research aims to analyze the difficulties of fourth grade students at SDN Mekarjaya 14 in solving mathematics story problems. This research uses qualitative research with an inductive method. This research aims to gain knowledge based on correct and reliable data and facts about students' mathematics learning difficulties in the form of story problems. The research instrument used was observation of test questions in the form of stories. The technique for checking the validity of the data is using triangulation. Based on the results of observations, there were still many respondents who made mistakes in working on the questions, including mistakes in changing story questions into mathematical sentences and using arithmetic operations. In general, students have difficulty working on story problems which are presented in the form of story problems. Apart from that, respondents also did not master multiplying results up to 100. In accordance with findings in the field, it can be concluded that there were difficulties experienced by respondents, including difficulties in understanding concepts and material,master and use arithmetic operations, for example multiplication and division. Meanwhile, the factors that caused respondents to experience difficulty learning mixed arithmetic operations included their lack of mastery of the concepts of multiplication and division, and the lack of time provided by respondents to repeat lessons at home.    

Computational thinking is a way of thinking that students must have. Currently, many students do not yet know how computing can be applied in mathematics learning. For this reason, this research focuses on analyzing students' computational thinking in solving mathematical problems. This research takes the type of literature study research by identifying and evaluating the results of previous research. Data analysis was carried out using an interactive model which uses 4 steps in the analysis stages, namely: 1) Data collection, 2) Data condensation, 3) Data presentation and 4) Data verification. This research identified 3 previous articles. From the results of this research, it is found that computational thinking in solving mathematical problems can still be said to be not very good..

This research aims to understand and analyze the mathematics learning difficulties faced by class VII students at SMPN 35 Medan. Through a qualitative descriptive approach, this research explores the factors that cause learning difficulties and provides solutions that can be implemented. The research method involves written tests and interviews with students and teachers. The results of the research reveal that students face challenges in understanding basic concepts such as algebra, linear equations, equivalent and non-equivalent comparisons, as well as plane figures and spatial figures. Internal and external factors, such as students’ cognitive abilities and less effective teaching methods, influence their mathematics performance. This research suggests a more interactive learning approach, training for teachers, collaboration between schools and parents, and regular evaluation to improve students’ mathematical understanding and performance in the future. Thus, this research makes a significant contribution to efforts to improve the quality of mathematics learning in schools.

The aim of this research is to obtain significant data and analyze the influence of the Team Assisted Individualization (T.A.I) learning model on the ability to solve mathematical problems on the subject of linear programming in class X students at MA Al Ittihad Sawangan Depok. The research method used is a quasi-experimental method (quasi-experiment). Sampling was carried out using a cluster random sampling technique with a research sample of 40 students, namely 20 students in class X IPS 2 as the experimental class and 20 X IPS 1 as the control class. The analysis technique used is a comparative analysis technique with the t-test, at a significance level of α= 0,05. The analytical requirements tests used in this research are the Chi-Square test for normality test and Fisher's test for homogeneity test. At a significance level of 0,05 with the Chi-Square test in the experimental class the price X2count <X2table (-33,38 < 9,488) while for the control class the price Homogeneity test at a significance level of 0.05 with Fisher's test, obtained F-count = 1,642 and F-table = 2,165 with a significance level of α= 0,05. Because Fcount < Ftable, H0 is accepted, so it can be concluded that the two classes have the same or homogeneous variance. Hypothesis testing uses the t-test with a significance level of α= 0,05. From the calculation results, t-count = 3,619, while ttable with degrees of freedom = 38 is 2,026, meaning t-count > t-table. Thus H0 is rejected and H1 is accepted. This research concludes that mathematical problem solving abilities using the Team Assisted Individualization (T.A.I) learning model are better than mathematical problem solving abilities using the Expository model.

Student learning outcomes at SMP Negeri 2 Telukjambe Barat in mathematics was poor, which prompted this study. Consequently, educational tools that enhance pupils' mathematical understanding must be put into place. The purpose of this classroom action study is to determine whether the ninth graders at SMPN 2 Teluk Jambe Barat can enhance their learning outcomes by using actual object media into curved sided space constructing materials. Of the total number of pupils, 39 are female and 16 are male. The project seeks to discover how to construct curved-sided rooms using actual things at SMPN 2 Telukjambe Barat, Karawang Regency. I conducted classroom action research for two cycles. Planning, doing, observing, and reflecting are the four phases that make up each cycle. Learning results improve with each cycle; cycle (1) shows a 35,13 percent improvement. In cycle (2), however, a rise of 39,49 was seen. Results in terms of knowledge gained improve with each cycle. The average score in cycle 1 increased from 38,46 before the exam to 73,59 after the test. In Cycle 1, learning outcomes increased by 35,13%, but only 66,67 percent reached the KKM. Results showed an improvement from an average pre-test score of 43,85 to an average post-test score of 83,33 in cycle 2. A mere 87,17% of participants were able to attain the KKM in cycle 2, despite a 39,49% improvement in learning outcomes overall. Research conducted during the 2022–2023 school year at SMP Negeri 2 Telukjambe Barat's class IX A found that students' mathematical understanding of curved-sided geometric objects might be enhanced via the use of actual object media.
