About this worksheet

Informative writing grows from facts that teach the reader something. At this age, children often add opinions, loose associations, or details that are true but do not support the topic sentence. This worksheet asks students to choose the fact that belongs and the sentence that defines a word clearly. The items show a topic sentence, a word, or a research question first, then offer details that are factual, opinion-based, or off topic.

Because the work is multiple choice, students can focus on relevance and truth rather than spelling or handwriting. A good fact should answer the question, explain the topic, or add a specific piece of information. If a detail tells what someone likes best, it may be interesting, but it is not doing the job of an informative fact.

What your child will learn

Choose facts that support a topic sentence
Tell informative facts from opinions
Choose a clear definition of a word
Remove unrelated information from an informative paragraph

Common Core standard: W.3.2

Worked example

Common mistake

Adding an opinion because it sounds lively, even though informative writing needs facts.
