Main idea across paragraphs

Find the main idea of a passage with more than one paragraph by combining what each paragraph contributes.

A whole passage can have several paragraphs, and each one might focus on a different detail -- but they usually all point back to ONE big main idea for the whole passage. Your job is to notice what all the paragraphs have in common.

Paragraph 1: Sea turtles hatch on sandy beaches at night. Paragraph 2: Baby turtles crawl toward the moonlight reflecting on the ocean. Paragraph 3: Once in the water, they swim for days without stopping to rest. Each paragraph covers a different moment, but together they tell one story: a sea turtle journey from beach to ocean.

📋 For the teacher
Teach it (10–15 min):
  • Read one paragraph at a time and pause to ask, "What did THIS paragraph add?" before moving on.
  • After all paragraphs, ask your child to say the whole-passage main idea in one sentence, in their own words.
  • Try a simple web or list: paragraph numbers around the edge, main idea in the middle circle.
  • If they name a detail instead of the big combined idea, ask, "does that cover every paragraph, or just one?"
Talk about it:
  • How do you find a main idea that stretches across several paragraphs?
  • What is one clue that two paragraphs share the same main idea?
  • Have you read a book where every chapter added to one big idea?

Mastery looks like: They combine the content of multiple paragraphs into one accurate main-idea statement for the whole passage.

Common stumbles: Naming the main idea of only the first paragraph and ignoring the rest; listing every detail instead of finding the shared big idea.
