Early reading ability is a basic skill that is important to be mastered by early grade students as a foundation for learning at a higher level. However, based on observations in class 1B of SD Negeri 104202 Bandar Setia Village, it was found that many students had difficulty in early reading, such as recognizing letters, combining letters into words, and understanding the meaning of simple words. This study aims to improve students' early reading ability through the use of picture media. This study uses the Classroom Action Research (CAR) method which is carried out in two cycles. Each cycle consists of the stages of planning, implementation, observation, and reflection. The subjects of this study were 29 students of class 1B of SD Negeri 104202 Bandar Setia Village. This study was conducted at SD Negeri 104202 Bandar Setia Village on Jl. Terusan Dusun V, Bandar Khalifah, Kec. Percut Sei Tuan, Deli Serdang Regency. Data were collected through observation, reading ability test results, and documentation. The results showed that the use of picture media significantly improved students' early reading ability. The improvement is seen from the results of the reading ability test, active student participation during learning, and increased student interest in learning. This can be seen from the results of the assessment carried out starting from the pre-cycle, cycle 1 and cycle 2. The use of visual media to improve Indonesian literacy in elementary schools can improve achievement, ability, and improve student learning outcomes at SD Negeri 104202 Bandar Setia Village. In addition, image media helps students understand the material more easily in a fun and interesting way. The conclusion of this study is that image media is effective as a learning aid to improve early reading skills in early grades. It is hoped that teachers can continue to develop visual-based learning media to create a more interesting and interactive learning atmosphere.

This research aims to analyze the effect of using time board media in increasing students' conceptual understanding of time material in class 1 of SD Negeri 104202 Bandar Setia. The background to this research stems from students' low understanding of the concept of time due to learning methods that are still abstract. The research method used is Classroom Action Research (PTK) with the Kemmis and McTaggart model which consists of two cycles. Each cycle includes planning, implementation, observation, and reflection. The research results show that the use of time board media can significantly increase students' understanding of the concept of time. In pre-action, only 24.1% of students achieved good understanding, whereas after implementing time board media in the second cycle, this percentage increased to 72.4%. This increase shows that the time board media is effective in helping students understand the concept of time concretely. Thus, the use of time board media is recommended as an innovative learning strategy in increasing understanding of mathematical concepts in early grade students.

This study aims to improve the understanding of addition concepts of numbers 1-10 in first-grade elementary school students through the use of number cube learning media. The research method used is an experimental method with a pre-test and post-test design. The research subjects were first-grade students divided into two groups: an experimental group and a control group. The experimental group was taught using number cube learning media, while the control group was taught using conventional methods. Data were collected through tests of understanding the addition concepts of numbers 1-10 before and after learning. The results showed a significant increase in the understanding of addition concepts of numbers 1-10 in the experimental group that used number cube learning media compared to the control group. The use of number cubes provides a concrete and interactive visual representation, thus helping students understand the concept of addition more effectively. This indicates that number cube learning media is effective in improving the understanding of addition concepts of numbers 1-10 in first-grade students. This study recommends the use of number cube learning media as an innovative and effective alternative learning method to improve the understanding of mathematical concepts in young children. Further research can be conducted to investigate the effectiveness of number cube learning media on other mathematical materials and at different educational levels. In addition, further research is needed on the development of more varied and interesting number cube learning media for students.
