Early age is often referred to as the golden age, where children begin to experience rapid growth and development. Children begin to experience growth in height, weight gain, development of thought patterns, and development of creativity. Given the importance of the role of early childhood education, educators as facilitators should present interesting and relevant learning to children's growth and development including their creativity. One of the appropriate learning methods for the development of children's creativity is the method of learning to play with natural materials. This study aims to improve the creativity development of trained children optimally by using the method of playing natural materials. The role of early childhood education in formal schools has a major role in the development of children's creativity. This research was conducted in TK Krajan 02 Village with a total of 8 children as respondents. After observation, it can be seen that learning in TK Krajan 02 Village is still considered monotonous so that children's creativity is still not optimally developed. From these problems, researchers used the method of playing natural materials to improve the development of children's creativity. This research is an experimental research using two cycles in the study. From the pre-cycle, cycle 1 and cycle 2, it can be seen that the development of children's creativity increases with the method of playing with natural materials. In the pre-cycle, the creativity level of kindergarten children in Krajan 02 Village is still in the medium and low categories. After cycles 1 and 2, the level of children's creativity development has increased in the medium to high category. Thus, it can be said that the method of playing with natural materials can increase the creativity development of trained children optimally.
