The transition from kindergarten to primary school is a key link in improving the quality of preschool education. At present, kindergarten thematic curriculum faces the dual dilemma of “primary school tendency” and “insufficient transition” in implementing the transition from kindergarten to primary school. Taking “kindergarten-college cooperation” as the research background and the senior class thematic curriculum Graphic Kingdom: Amazing Made-in-Chinaas an example, this paper explores the design rationale and practical strategies of kindergarten thematic curriculum from the perspective of scientific transition from kindergarten to primary school. Based on children’s life experience and existing cognitive level, with tangram as the carrier, the curriculum follows the principle of “de-primary-schoolization”, transforms the perception of pictographic characters and mathematical graphic cognition into gamified, contextualized and operational thematic activities, and realizes scientific transition through horizontal integration and vertical progression, allowing children to “learn through play, learn through doing, and learn through life”, effectively supporting children’s preparation for school.
