What This Standard Means

What Students Need to Do

Students choose exact nouns, verbs, and technical terms that explain a complex subject accurately. They adjust vocabulary and tone for the discipline, purpose, and readers' knowledge.

What Mastery Looks Like

A student can replace vague words such as “things,” “stuff,” and “got” with accurate terms. They use technical vocabulary correctly, define unfamiliar terms when needed, and keep the tone consistent.

Common Misconceptions

Students may think precision means using longer words or adding as much jargon as possible. They may use technical terms incorrectly, leave abbreviations unexplained, or ignore the reader's background knowledge.

How to Assess It

Exit ticket: Rewrite “The thing changed when heat was added” for a grade 10 lab report. Underline two precise terms and explain one choice.

  3. Play Vocabulary Swap, where teams replace vague words in technical sentences and earn points for accurate, audience-friendly revisions.

  4. Compare two phone setup guides, then rewrite one set of directions for a first-time user unfamiliar with technical terms.
