The limited number of teachers teaching students with intellectual disabilities presents a challenge in providing learning materials, especially in mathematics learning, so appropriate learning media are needed for students with intellectual disabilities based on grade level and type of intellectual disability. The development of cross-class learning media assisted by Canva is one good alternative solution to solve this problem. Based on this information, this study aims to develop cross-class learning media assisted by Canva to improve the mathematical understanding of students with intellectual disabilities. This research is a development research using the ADDIE model. The results of this study indicate that the developed learning media is feasible to use. The results of the implementation of the use of the developed media show that most students focus on learning using the media, encourage students to work independently and show quite good enthusiasm for learning.
