The video tutorial covers lesson three on making scaled copies. It begins with an introduction to the learning goals, which include understanding operations to produce scaled copies and drawing them using a given scale factor. The first activity involves creating a scaled copy of a figure using a scale factor of three, while the second activity uses a scale factor of half. The tutorial also analyzes the work of two students, Diego and Jada, who use different operations to scale a polygon. The lesson concludes with a final activity and encourages students to ask questions during office hours if needed.
