From Wikipedia, the free encyclopedia. A graphic organizer, also known as a knowledge map, concept map, story map (or storymap), cognitive organizer, advance organizer, or concept diagram, is a communication tool that uses visual symbols to express knowledge, concepts, thoughts, or ideas, and the relationships between them.
This type of graphic organizer however, always allows change and new concepts to be added. The Rubber Sheet Analogy states that concept positions on a map can continuously change, while always maintaining the same relationship with the other ideas on the map. Start with a main idea, topic, or issue to focus on.
