Meningkatkan Kemampuan Mengenal Geometri pada Anak Usia 5-6 Tahun Melalui Metode Permainan Balok di TK Masjid Nurul Muslimin

This study aims to improve the ability to recognize geometry in children aged 5–6 years through the block game method at Nurul Muslimin Mosque Kindergarten. The research was conducted as Classroom Action Research (CAR) with a qualitative approach. The subjects of this study were children in group A at Nurul Muslimin Mosque Kindergarten, with research carried out collaboratively between researchers, teachers, and the principal. The procedure followed a systematic design consisting of two cycles, each divided into four stages: planning, implementation, observation, and reflection. Data were collected through observation, testing, and documentation to measure the development of children's ability to recognize geometric concepts. The results showed a significant increase in children's ability to recognize geometry through the block game method. In the pre-cycle, only 23.33% of children demonstrated the expected level of ability. After the first cycle, this figure increased to 53.33%, indicating moderate progress. By the end of the second cycle, 86.66% of the children had reached the expected competency, showing a remarkable improvement. These findings highlight the effectiveness of the block game method in fostering cognitive development, particularly in the area of early geometry recognition among preschool-aged children. The conclusion of this study emphasizes that implementing block games as a teaching strategy not only enhances children's recognition of geometric shapes but also supports active learning, creativity, and collaboration. Therefore, educators are encouraged to integrate play-based learning methods such as block games into early childhood education programs to improve fundamental mathematical concepts and prepare children for higher learning stages.
