Finding the main idea of a reading selection is one of the most difficult skills a reader must manage . This skill is made easier by knowing how to identify the supporting details in a reading selection.)

When the main idea of a reading selection is clearly stated, it usually follows one of the following patterns of organization:

• Some paragraphs state the main idea as a topic sentence. The topic sentence is then followed by supporting details to back up the main idea.
• Some paragraphs begin with the supporting details and state the main idea as a closing statement.
• Another pattern starts with supporting details then states the main idea followed by more support.

When the main idea of a reading selection is NOT clearly stated, it is called an implied main idea.

Whether the main idea is clearly stated or implied, asking the following questions will help you identify the main idea with success:

1. What is the topic of the paragraph?
2. What does the author want you to know about that topic?
