Reflecting on the impact of the Covid-19 pandemic, which requires all activities to be carried out online, there is a need for flexible teaching materials that can be used online or offline. One alternative is to create interactive electronic student worksheets based on Live-worksheets. This study aims to produce electronic student worksheets based on Live-worksheets with Problem Based Learning model on three-dimensional shape materials that meet the valid and practical categories. This research is a research and development of a 4-D Thiagarajan model, namely define, design, development, and disseminate. This research instrument consists of a sheet of validity and practicality. The results showed that the development of electronic student worksheets based on Live-worksheets with the Problem Based Learning model on three-dimensional shape materials was included in the categories: (1) very valid based on 48 aspects of assessment consisting of 12 aspects of material assessment, 14 aspects of construction assessment, 7 aspects of language assessment, and 15 aspect of media assessment with a tendency to strongly agree on aspects of electronic student worksheets validity assessment, and (2) very practical based on 8 aspects of assessment with a tendency to strongly agree on aspects of practicality assessment.
