How to teach this

Teach summary as the test of main idea. If your student can shrink the passage to two sentences that a stranger would understand, the first sentence is almost always the main idea. Watch for answers that are true and vivid but too narrow; vividness is not importance.

Watch for: The most interesting fact is usually a detail, not the main idea. The main idea is the sentence all the other sentences work for. A main idea that only covers one paragraph is too small; it should fit the whole passage.

Common questions about main idea and details

What if the passage never states its main idea?
Then the reader builds it, which is the grade-5 skill. Have your student finish "this passage is mostly arguing that..." in their own words, then check it against every paragraph. Our answer choices include the too-broad and too-narrow traps on purpose.
How does main idea connect to writing a summary?
A summary is a main idea plus its key support, with the small stuff left out. A student who can spot the main idea can write a real summary instead of just retelling the passage detail by detail, which is exactly what upper grades demand.
