The Standard

Develop the topic with well-chosen, relevant, and sufficient facts, extended definitions, concrete details, quotations, or other information and examples appropriate to the audience's knowledge of the topic.

What This Standard Means

Students need to build an informative piece with evidence that fits the topic and reader. They should choose facts, examples, details, and quotes that explain the idea clearly, not just fill space. They also need to judge what the audience already knows and add enough context.

Mastery looks like a paragraph or essay where every detail earns its place. The evidence explains, proves, or clarifies the point. Students often get stuck using vague examples, dropping in quotes without explanation, or giving too much background to a reader who does not need it.

Ways to Teach It

Give students three sources on school start times and have them highlight only details that would help ninth graders understand the issue.
Ask students to revise one body paragraph by adding one fact, one concrete example, and one sentence explaining a quote.
Use an exit ticket where students label one piece of evidence as strong, weak, or off-topic and explain why.
Have students compare a phone review for teens and one for tech experts, then list how the evidence changes for each audience.
