This study aims to analyze the improvement of children's cognitive ability in sorting patterns through the use of Flannel bags in group B RA Al Islam Pitoro. The ability to sort patterns is an important aspect in the cognitive development of early childhood, because it helps children think logically, systematically, and builds a foundation for understanding mathematical concepts such as number patterns, shapes, and colors. Therefore, innovative and interesting learning methods are needed so that children can more easily understand the concept of patterns. The research method used is quantitative with a quasi-experimental design involving two groups, namely the experimental group using Flannel bags and the control group learning with conventional methods. Data collection was carried out through cognitive tests, observations, and interviews with teachers and parents to determine children's development before and after the intervention. The results showed that the use of Flannel bags significantly improved children's ability to recognize, arrange, and predict repeating patterns compared to conventional learning methods. In addition, observations and interviews showed an increase in children's motivation, enthusiasm, and active participation in learning activities. In conclusion, Flannel bags are an effective learning tool to improve children's cognitive abilities in sorting patterns. Therefore, it is recommended for educators to adopt this media as an innovative, interactive, and fun learning strategy for early childhood.
