The development of plotagon-based video media is one of the innovations that aims to improve students' understanding of the concept of counting numbers. Although the material of integers is very important for grade 2 elementary school students, often students do not have enough resources to understand thoroughly. This study aims to measure the validity, practicality, and effectiveness of learning media developed using the Research and Development (R&D) method with the ADDIE model. The results of the media validation test showed presentations reaching 75% and 84%, while the material validation test gave a presentation of 80%, which means both were classified as valid. The results of the media practicality test given to teachers showed an average score of 97%, including in the very practical category. While the results of the effectiveness test show a sig. value of 0.000
