The Standard

Provide a concluding statement or section that follows from and supports the information or explanation presented (e.g., articulating implications or the significance of the topic).

What This Standard Means

Students need to end an informational or explanatory piece in a way that fits the ideas they already developed. The ending should not feel tacked on. It should help readers see why the topic matters, what the evidence adds up to, or what larger point follows from the explanation.

Mastery looks like a conclusion that echoes the main idea without copying the introduction. Strong writers point to significance, consequences, patterns, or next questions. Students often get stuck by writing “In conclusion,” repeating every detail, adding brand-new evidence, or ending with a vague moral that does not match the paper.

Ways to Teach It

Give students three weak conclusions and have them revise each using one strategy: significance, implication, or unanswered question.
Ask students to write: What should a reader understand differently after reading my explanation, and why does that matter?
Collect only the final paragraph and have students label the sentence that connects back to the main idea.
Show a news explainer ending and ask how the final paragraph helps readers see the issue’s larger impact.
