A child's ability to understand what he or she reads depends largely upon the ability to locate the main idea of a passage and identify the details that support it. Practice Makes Perfect: Main Idea covers identifying the main idea and supporting details in both fiction and nonfiction text. To allow for the greatest variety of practice, the passages are not complete stories. Students will identify the main idea in fiction and nonfiction text, will locate supporting details in fiction and nonfiction text, will identify topic sentences in paragraphs, and will choose the best title for a passage. Includes answer key. Reproducible. 48 pages.
