The video tutorial introduces fifth-grade students to the concept of volume by using cubes. It emphasizes the importance of counting cubes rather than faces and provides examples to illustrate this concept. The tutorial also explains the idea of hidden cubes and how to draw and double cubes to understand volume better. A practical example involving a student's cube structure is used to highlight common mistakes and clarify the concept.
