    • Divide the chart into two columns or sections: one for the main idea, one for details.
    • Consider color coding: blue for the main idea, green for details.
  2. Define Key Terms
    • Write a concise definition of “Main Idea.” Example: “The central point or purpose that the author wants the reader to understand.”
    • Define “Details” similarly: “Specific facts, examples, or evidence that support the main idea.”
  3. Add Visual Examples
