<![CDATA[The primary issue underlying this study is the low level of students' mathematical critical thinking skills, combined with a lack of instructional innovations capable of fostering active classroom engagement. To address this challenge, this study prioritizes evaluating the feasibility, practicality, and effectiveness of interactive learning media developed via Canva and Wordwall, integrated with the Discovery Learning model. Utilizing the Research and Development (R&D) method under the ADDIE framework. Data were gathered through a limited trial involving 6 students, an expanded trial with 29 students, and a product trial conducted across two classes—experimental and control—. The data collection instruments included test and non-test methods, which were subsequently analyzed using SPSS and Microsoft Excel. The product evaluation yielded highly satisfying results: media expert validation reached 90.00% and material expert validation stood at 91.11% (both highly valid category), while the practicality score reached 87.67% (highly practical). Furthermore, the effectiveness test demonstrated a significant difference in mathematical critical thinking skills between the two groups, with the experimental class successfully outperforming the control class.]]>
