Geometry learning outcomes are lower than other mathematical fields, so media are needed to overcome students' difficulties solving geometry problems. This study aims to produce a product in online learning media for scaffolding-based geometry materials using Microsoft Form. There are three stages of Research and Development research, namely preliminary research, prototyping, and assessment. The validation results show that the scaffolding-based media developed is valid with a percentage of 76%. Field notes show that the scaffolding-based media developed can be used easily and practically by lecturers and students. A positive response was also given by 30 third semester students who used media in learning circle material. The test results showed that 73% of the total number of students scored no less than 70. Therefore, the scaffolding-based media developed was declared valid, practical, and effective in learning circle material.
