The purpose of this study is to develop E-LKPD with a scientific approach to increase students' interest in learning circle material at MI Al Hidayah Mangli Jember which is valid. Judging from the current development of education, educators are required to be able to innovate in making and creating various learning teaching materials. However, based on observations, the learning teaching materials used have not been effective and have not been able to accommodate students to be active in the learning process. The development of Student Worksheets (E-LKPD) with a scientific approach to circle materials to increase students' interest in learning is an effort to overcome problems found in the learning process. This is also to help students better understand the learning material, especially circle material, because it is a difficult material to raise. The development of this E-LKPD uses the R&D stages of the ADDIE model, namely Analysis, Design, Development, Implementation, and Evaluation. The subjects of this research consist of: First, 3 validator lecturers, namely: media experts, material experts, and linguists. Second, one mathematics teacher and 30 students of class VI MI Al Hidayah Mangli Jember. The data collection instruments used are teacher interview questionnaires, student observation questionnaires, validity questionnaires, and practicality questionnaires. The validity test result of the e-LKPD is 90% with a very valid category and the result of the practicality test is 91% with a very practical category. So that the e-LKPD developed has met the criteria and can be used in the mathematics learning process.
