The Learning Trajectory of Entrepreneurship Arithmetic Content Using a Traditional Market

Learning the content of entrepreneurship arithmetic is an extension of social arithmetic that focuses on mathematical calculations in business or creative economy. Most teachers do not link students' daily activities to classroom teaching and learning on traditional markets around the environment. This significantly affects the interest in learning the material content. Therefore, this study aimed to design a learning trajectory of entrepreneurship arithmetic content using a Badung traditional market. A design approach with three stages was used, including preliminary design, teaching experiment, and retrospective analysis. The results showed that the learning trajectory can be practiced using local contexts, such as traditional or other students' daily activities. Moreover, the Badung Traditional Market stimulates students to understand the entrepreneurship arithmetic content from five activities. These include Engagement with content and context, Story of Entrepreneurship on Video, Concept Deepening, Collaborate to Solve Problems, and Making Conclusions. The learning trajectory is essential in understanding the mathematical concepts of expenditure, income, profits, and loss within the trading activities.
