What This Standard Means
What Students Need to Do
- Students build an informative piece with accurate facts, clear definitions, specific details, examples, and useful quotations. They select enough support and adjust it for what their readers already know.
What Mastery Looks Like
- Students choose accurate details that clearly support each point. They provide enough facts, definitions, examples, and quotations for the intended reader, then explain how each detail helps.
Common Misconceptions
- Students may add facts that are interesting but do not explain the topic. They may drop in quotations without explaining them, provide too little support, or assume readers know technical terms.
How to Assess It
- Exit ticket: Expand “Solar panels can lower school energy costs” with one fact, one concrete example, and a definition written for parents.

Have students create a one-page safety guide for new lab students using clear definitions, facts, examples, and reader-friendly details.
