The fact shows that students with learning disability need media of learning mathematics. The purpose of this study was to (1) develop interactive learning multimedia of power point, and (2) examine the effectiveness of power point in mathematics learning. The sample was a group of students in elementary school in Ngawi, East Java, Indonesia, especially those with learning disability. This study was a research and development comprising three stages: preliminary study, product development, and testing the effectiveness of the product. The data were collected through questionnaires, interviews and tests, then analyzed by descriptive qualitative, and t-test was to analize the effect of the product. In the development stage, the result showed that Experts validation is high as indicated by the mean score of 4.50 for the learning material, and the mean score of 4.44 for quality of the multimedia. The trial results showed that the quality of multimedia was very good as indicated by the mean score of 4.32. In term of the effectiveness of the product, the result from the t-test shows an increase of 14.27 (21.88%). This means that the interactive learning multimedia of power point improves the achievement of mathematic learning for students with learning disability in mathematics.
