The Learning and Teaching Geometry project (LTG) creates five video case modules for use in professional development of middle school mathematics teachers. The materials are designed to develop teachers' understanding of mathematics knowledge for teaching similarity. Module I, the foundation module, focuses on a thorough grounding of similarity and contains 6-8 video case sessions. The four extension modules offer options for further exploration: (1) Definitions and Theorems; (2) The Role of Language in Geometry; (3) Choosing and Using Technological Tools; and (4) Bridging to High School Geometry. In total, 18-24 video cases are produced, which, taken together, form the curriculum of a 45 to 60-hour professional development course.

学与教几何项目(LTG)创建了五个视频案例模块，用于中学数学教师的专业发展。教材的设计是为了培养教师对数学知识的理解，以达到教学的相似性。模块I是基础模块，重点放在相似性的全面基础上，包含6-8个视频案例会议。四个扩展模块提供了进一步探索的选项：(1)定义和定理；(2)语言在几何中的作用；(3)选择和使用技术工具；(4)与高中几何衔接。总共制作了18到24个视频案例，这些案例加在一起，构成了45到60个小时的专业发展课程的课程。
