The document discusses the use of whiteboards in the classroom and how they are changing how teachers teach. Whiteboards can be used across curriculums and benefit all types of learners through visual, tactile, and audio engagement. An interactive whiteboard interfaces a computer and projector to display content on its surface, allowing teachers to easily integrate lessons. While expensive, whiteboards facilitate universal design and creative lesson planning. Grants may help schools that cannot otherwise afford this technology.
