What This Standard Means

What Students Need to Do: Students write in a formal voice that is clear and holds a reader's attention. They choose words, evidence, and conventions that fit the subject they are writing about.
What Mastery Looks Like: A student can replace 'This totally proves it' with a precise claim that explains what the evidence supports. Their tone stays consistent, and their word choices fit a history essay, lab report, or public comment.
Common Misconceptions: Students may think formal writing means using long words and stiff sentences. They may slip into slang, treat one example as proof, or use the same tone for every subject.
How to Assess It: Rewrite 'The New Deal totally fixed everything' as two sentences for a history essay, using this fact: unemployment remained above 14 percent in 1937. Keep the tone formal and the claim precise.

Ways to Teach It

Give pairs a printed lab report conclusion and a newspaper opinion paragraph about plastic waste; have them highlight differences in word choice and evidence.
Ask students to write how they would request a later school start time in a letter to the school board, then explain their tone choices.
Give teams cards reading 'totally proves' and 'the author is awesome'; have them replace each phrase in a sentence about a class poem.
Post 'Proposal: Move the bus stop two blocks from the library' and have students write a formal, three-sentence public comment with a specific request.
