Regarding the concepts of main idea and supporting sentences:
Recognizing the main idea is the most important key to good comprehension. The main idea is a general “umbrella” idea; all the specific supporting material of the passage fits under it.
Three strategies that will help you find the main idea are to 1) look for general versus specific ideas; 2) use the topic (the general subject of a section) to lead you to the main idea; 3) use key words—verbal clues that lead you to a main idea.
The main idea often appears at the beginning of a paragraph, though it may appear elsewhere in a paragraph.
Major and minor details provide the added information you need to make sense of a main idea.
List words and addition words can help you find major and minor supporting details.
Outlining, mapping, and summarizing are useful note-taking strategies.
Outlines show the relationship between the main idea, major details, and minor details of a passage.
Maps are very visual outlines.
Writing a definition and summarizing an example is a good way to take notes on a new term.
