Cognitive abilities in early childhood, especially in recognizing patterns and logical thinking, still require interesting and innovative learning media, therefore research intends to build learning media in the form of a pull cart coding activity book as a learning medium for early childhood so that it is more fun. This research employs R & D (Research and Development) approach with ADDIE model which has five stages, namely: Analysis, Design, Development, Implementation, and Evaluation. The results obtained that the validation of material experts obtained 91.66% with a very feasible category, then the percentage value of media experts obtained 96.15% with a very feasible category, and the results of implementation carried out by the teacher obtained a percentage of 81.25% with a very feasible category. Based on the results of this activity, the medium of the pull cart coding exercise book is highly feasible with the medium's feasibility in the very feasible category as a learning medium for early childhood.
