Two Kinds of Weak Opinion Paragraphs
Ms. Brennan's fourth graders have just finished an opinion-writing unit on whether recess should be longer. She scores 24 paragraphs against a four-point rubric covering claim, reasons with evidence, organization, and conventions, and finds two clusters. Fifteen students state a clear position and two reasons but never connect the reasons to the claim ('Recess should be longer. We have 20 minutes. Some kids do not finish snack.'). Nine students use linking words and paragraph structure but support their reasons with invented statistics ('87% of kids agree'). Three students fall into both clusters. The district requires 30 minutes of writing a day, the informational-writing unit begins next Monday, and Ms. Brennan has one 10-minute whole-class mini-lesson slot plus two 12-minute small-group rotations tomorrow.
1. Which problem should Ms. Brennan treat as the higher priority, and on what criterion should that decision rest?

Prioritize the fifteen-student elaboration problem, but choose it on a developmental criterion rather than on headcount alone.
Those students have a claim and reasons, which is the harder conceptual work of argument, and they are missing the connective reasoning that explains why a reason supports the claim. That is the next step in the genre and it applies directly to the informational unit, where explanation sentences do the same job. The invented-statistics group has a narrower, more technical problem: they have absorbed that evidence should sound impressive and have not learned that evidence must be true and traceable. That is fixable with a clear rule and a real data source, and it will not block their informational writing in the same way.
Headcount reinforces the choice but does not settle it. If only three students lacked elaboration, small-group support would be the efficient route and the class lesson would target evidence instead.
2. Design the 10-minute mini-lesson and say what each small group will do and produce.

Mini-lesson: display two versions of the same paragraph, one with the reason parked next to the claim and one with a sentence bridging them ('We need more time because twenty minutes does not cover snack and bathroom breaks, so kids come in still hungry'). Ask students what the second version does that the first does not, and elicit the bridge sentence as a move, not a formula. Then have each student add one bridge sentence to a paragraph in their folder.
Rotation A, the fifteen elaborators: revise one paragraph so every reason has a 'because' or 'so' sentence that explains the link. Product: two bridge sentences, one per reason.
Rotation B, the nine evidence writers: replace invented numbers with real data by running a three-question class survey during the rotation and citing it correctly. Product: one sentence naming the source and the count, such as 'In our class survey, 17 of 24 students said they run out of time to eat.'
The three overlap students go to Rotation B and add bridge sentences in the following day's warm-up.
3. How should Ms. Brennan address the invented statistics so the habit does not return in the informational unit?
Read the worked answer
She should name the habit explicitly rather than only correcting the paragraphs, because invented statistics are a genre and media problem, not a one-time slip.
A short, concrete frame works: evidence has to be something a reader could check, and a number that sounds convincing is not the same as a number that is true. Have students test each other's evidence with the question 'where did this number come from?' and sort examples into three piles - I counted it, someone told me, I made it up. The third pile is not a moral failure; it usually signals that the writer wanted authority and did not know where to get it.
Then supply legitimate sources so the rule is usable: class surveys, the school schedule, a principal's email, a news article the class reads together. Linking the rule to a source students can actually consult is what prevents the habit from recurring when informational writing raises the same demand.
