About this worksheet
Short nonfiction paragraphs, each with three sentences to choose from.
What kids practice
The main idea is what a paragraph is mostly about, and details tell more about it. Cause and effect explains why something happened and what happened because of it. Point of view is who is telling the story. Third graders find each of these in what they read and separate their own point of view from a character's.
Watch for
- Picking one interesting detail as the main idea.
- Mixing up the cause and the effect, especially when the effect comes first in the sentence.
- Thinking a story is first person just because a character talks in quotes.
It's free to print, with Fewer, Standard or More on the page and an answer key. See the full main idea, cause and effect, point of view guide for 3rd grade.
