About this worksheet

Informative writing begins with a topic sentence that tells the reader what the paragraph will explain. Many third graders either write a tiny detail, such as a color or one body part, or they write an opinion that belongs in a different kind of writing. This worksheet isolates the opening sentence of an informative paragraph. Students match topic sentences to groups of facts, identify sentences that are too narrow, and choose openings that fit a title.

Because each item has a correct answer, children can practice the decision before they write full paragraphs on their own. The best answers are broad enough to cover all the facts but still specific enough to guide the reader. This habit also helps children check whether later details still belong.

What your child will learn

  • Choose a topic sentence for an informative paragraph
  • Match a topic sentence to related facts
  • Avoid openings that are too narrow
  • Tell informative topic sentences from opinions

Common Core standard: W.3.2

Worked example

For facts about wings, nectar, and caterpillars, 'Butterflies are insects with interesting body parts and life stages' fits better than one detail about antennae.

Common mistake

Using one small fact as the topic sentence, which leaves the rest of the paragraph without a clear focus.

Helpful hint

The topic sentence should fit all the facts, not just one detail.
