The background of this research is base on how to importans teaching materials in learning process. Instructional materials that are expected to facilitate and guide students to learn independently, and make it easier to understand the concept correctly. Student activity sheet (LKS) that there have not been able to help students understand and remember math concepts well. Associated with the development of teaching materials in the form of discovery learning LKS based on the material logaritma and exponent. This study aims to determine how the validity and practicalities of discovery learning-based LKS. This type of research is the development of the 4-D models consists of four phases: phase define, design, develop, and disseminate. In this study is only conducted three phase. LKS validation results based discovery learning-based validator shows LKS very valid invention is about 4,70. Test the practicalities of the students showed discovery learning LKS based on the category of very practical is 86,1%. It can be concluded that the LKS-based discovery learning is very valid and very practical.
