This research was motivated by students' lack of understanding of fractions and limited mathematics learning media in schools. This is one of the factors in students' lack of motivation and enthusiasm for learning. The development of BIANKA (Mathematical Fraction Ferris Wheel) media is one solution to overcome this problem. This research was conducted at SDN Blotongan 02 Salatiga. This research uses the Research & Development (R&D) method with the ADDIE development model which consists of 5 stages, namely analysis, design, development, implementation, and evaluation. The method used in this research is quantitative descriptive. The data collection techniques used are observation, interviews, response questionnaires, tests, validation sheet instrument assessments, practicality and effectiveness. The media validation results were 96% in the "Very Good" category and the material validation results were 93.3% in the "Very Good" category. There is an average difference between the pretest and posttest scores because the Sig (2-tailed) value is 0.000 < 0.05, so Ho is rejected and H1 is accepted. So it can be concluded that there is a significant difference between mathematics learning outcomes in pretest and posttest data. so that the mathematical fraction Ferris wheel media is suitable for use in the learning
