Teaching an Interior Design Course? I always start with this powerpoint in the first week. The Elements of Design are the 'informal rules' in which interior designers work by to create a beautiful space. This PowerPoint is an interactive PowerPoint with multiple examples for students based on each of the elements of design. Couple this powerpoint with the Principles of Design PowerPoint (see separate listing) as the basis to your interior design class. Bonus - purchase 'The Principles and Elements Foldables' (separate listing) project for students to practice utilizing the elements and principles of design after reviewing this powerpoints.
