What are text structures?

Text structure is how a piece of nonfiction is organized. The five main ones are description, sequence, compare and contrast, cause and effect, and problem and solution. Signal words like first, both, because and to solve this give them away.

  • Five common structures organize most nonfiction.
  • Signal words hint at which one you're reading.
  • Knowing the structure helps kids find the important ideas.
Find the signal words, find the structure.

Why schools teach it

Structure tells you what to look for

If a passage compares frogs and toads, the key information is how they're alike and different. Third graders describe connections like comparison and cause and effect (RI.3.8), and fourth graders describe a text's overall structure (RI.4.5).

Each structure has a matching graphic organizer, like a Venn diagram for compare and contrast or a flow chart for sequence, which helps kids take notes and summarize.

What to say, and what to skip

Say this

  • What words give you a clue about how it's organized?
  • Is it telling steps in order, or comparing things?
  • What problem is described? How is it solved?
  • Which organizer would fit this text?

Skip this

  • Expecting one structure per passage.Longer texts mix structures. Find the main one.
  • Relying only on signal words.Words like then show up everywhere. Check the whole passage.
  • Treating it as a labeling quiz.The point is understanding the ideas, not just naming the type.

Spotting cause and effect

  1. Read the paragraph

    “Because it rained for five days, the river rose. As a result, the park flooded.”
  2. Circle the signal words

    because · as a result
  3. Name the cause and the effect

    rain (cause) → river rose → park flooded (effect)

Cause-and-effect texts often form a chain: one effect causes the next.
