<![CDATA[The use of printed book learning media with lots of writing is not effective for deaf students, resulting in low student conceptual understanding. Deaf students need learning media that can overcome their limitations in language and communication, by utilizing media that has a visual appearance. The purpose of this study is to develop valid interactive media with the Realistic Mathematics Education (RME) approach on the material of the area of flat shapes called "AISITARU". This study applies the Research and Development (R&D) research method with the ADDIE development model which is focused on the analysis, design, and development stages. This study produced an interactive learning media "AISITARU" with the results of the media expert validation assessment of 91.7% which is included in the very valid criteria, while the average score of the material expert is 87.6% with the very valid criteria. The results of the validation analysis of media experts and material experts of the "AISITARU" media obtained a combined average score of 89.65%, which is included in the very valid category. This proves that the "AISITARU" media meets the eligibility to be tested on deaf students in learning mathematics with the material of the area of flat shapes.]]>
