In order to teach Mr. Granger the information, I would first provide him with a visual aid such as a PowerPoint presentation or a handout with diagrams and pictures. This would help him to better understand the material. I would then explain the material in a step-by-step manner, breaking it down into smaller chunks and providing examples to illustrate each point. I would also provide him with additional resources such as books, articles, and websites that he can use to further his understanding of the material. Finally, I would encourage him to ask questions and provide feedback throughout the lesson to ensure that he is understanding the material.
