This research aims to develop an interactive media game called CacaBoomtown which is designed to help students' understanding of the concept of integers in a more fun and simple way. In addition, this study also aims to assess how feasible CacaBoomtown media is used as learning media in learning integers in grade IV. In this development, respondents consisted of one teacher and 37 fourth grade students. The method used is Research and Development (R&D) because researchers want to develop learning products in the form of Canva-based Interactive Games using the Hannafin and Peck (1988) model. This research was carried out up to the design stage. The results of the analysis show that the learning media used by teachers so far, such as student books and simple tools in the form of cups, have not been effective in building understanding of the concept of numerical numbers up to 10,000. Learners still have difficulty counting, understanding place value, and ordering and comparing numbers. The design stage resulted in a Canva-based CacaBoomtown media design that presents a simulation of buying and selling in the context of students' daily lives. This media is considered potential to be continued to the development stage because it incorporates visual elements, contextual, and play activities that are in accordance with the characteristics of learners.
