Common mistakes
Misconceptions students bring to main idea
Specific errors to watch for when reviewing student work — pulled from classroom research and teacher reports.
Choosing a detail instead of the main idea.
What to teach instead: A detail supports the main idea; it doesn't capture the whole text.
Selecting a topic too broad to be the main idea.
What to teach instead: The main idea is more specific than the general topic — it's a complete thought about it.
Assuming the title is always the main idea.
What to teach instead: Titles hint at the topic; the main idea is built from the body of the text.
