Introducing mathematics to early childhood is taught directly because children also have to see it concretely. Mathematics can’t be separated from everyday life, children also like mathematics if the way teachers and parents teach is fun and creative. Mathematics is not only an activity about counting, addition, subtraction, multiplication and division, but there are many mathematical activities that are part of our daily life. One of the learning methods in Early Childhood Education is the assignment method, using the assignment method especially in introducing the concept of introducing mathematics to early childhood in geometric shapes material, which can make it easier for children to understand geometric shapes around children in a fun way. Through fun activities that are liked by children and which can be easily understood by children, especially in introducing geometric shapes to early childhood. There are several kinds of learning methods that exist in the school, namely the play method, the field trip method, the conversation method, the demonstration method, the project method, the storytelling method, and the assignment method. The method used in this research is descriptive qualitative research. Geometry material is an introduction to the concept of forms such as circles, triangles, and squares. From the findings of research conducted by researchers at TK Mutiara Ibu Jambi related to learning the introduction of mathematics to geometry material used by teachers by using the assignment method in introducing mathematics learning, especially in geometry material, the research findings were when teachers used the assignment method in introducing the introduction of mathematics to the material. geometry in early childhood, children can understand the concepts of geometry, it turns out that children can recognize geometric shapes, namely round shapes, triangle shapes, and square shapes, children can also distinguish colors according to geometric shapes that have been taught previously by the teacher.
