How to teach this
Use the umbrella: draw one on scratch paper, write the main idea on top, and hang the details underneath. If a detail doesn't fit under the umbrella, it isn't supporting anything. Asking what is this MOSTLY about, with the stress on mostly, steers kids away from the shiniest single fact.
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
- How do I explain main idea versus details?
- The umbrella and the raindrops. The main idea is the umbrella big enough to cover every sentence; details are the drops it catches. If your child picks a detail, ask whether the whole passage fits under it, and a detail-umbrella leaves most of the passage standing in the rain.
- Why does my child always pick the most exciting fact?
- Because exciting facts are memorable, and memory feels like importance at this age. The fix is the mostly question: is the whole passage mostly about that fact, or did it appear once? One appearance is a detail, no matter how good it is.
