Commas or Coherence? A Fifth-Grade Writing Decision
Mr. Blake's fifth graders wrote opinion essays on later school start times. On the district 4-point rubric, class averages were focus 3.4, organization 2.6, evidence 2.9, and conventions 2.2. Four students wrote single paragraphs containing six or more run-ons; two advanced writers organized well but never acknowledged a counterargument. The grade-level team proposes two weeks of comma and sentence-boundary drills during the 30-minute writing workshop. Mr. Blake has the same 30 minutes and the students' essays in hand. He must decide what to prioritize and how to keep the advanced writers growing.
1. What does the data suggest about priority? Is two weeks of comma drills defensible?
Read the worked answer
Conventions is the lowest average at 2.2, but the lowest score is not automatically the highest priority. Two other facts matter.
First, organization is 2.6 and evidence 2.9, and both sit closer to the core of the task: an opinion essay that is well punctuated but has no structure and no evidence still fails to persuade. Second, the run-on problem is concentrated in four students, while organization is a class-wide pattern. Two weeks of whole-class comma drills would spend the class's writing time on a weakness that is neither universal nor the most consequential.
That said, conventions cannot be ignored, and sentence boundaries are worth teaching. The defensible move is to teach sentence boundaries inside revision of the essays students already wrote, where the run-ons are visible and the fix improves clarity. A short daily mini-lesson on sentence combining and boundary marking, applied immediately to their own drafts, is likely to transfer better than isolated workbook drills.
So: keep conventions in the plan, shrink it from two weeks of drills to a recurring mini-lesson strand, and give the bulk of the time to organization and evidence.
2. Plan the two-week workshop. Include the daily structure and what the advanced writers do.

Daily structure (30 min): 8-10 min mini-lesson, 15 min writing and conferring, 5 min share or self-check.
Week 1 - Structure and sentences.
- Mini-lessons: what a claim needs; paragraphing an opinion essay (claim, reasons, evidence, conclusion); sentence boundaries using two or three run-ons from anonymous student drafts; sentence combining.
- Work time: students outline then draft a second essay on a new prompt, or restructure the first into paragraphs. The four students with run-ons get a focused conference and a self-editing checklist limited to three items.
Week 2 - Evidence and counterargument.
- Mini-lessons: what counts as relevant evidence; how to introduce a source; how to state and answer a counterargument.
- Work time: revision of the draft, then a short published piece for a class anthology.
Advanced writers: they do not repeat paragraphing. Their mini-lesson group works on counterargument and evidence quality: find the strongest objection, state it fairly, answer it with evidence. They can also serve as response partners for peers, but only after their own revision is underway, so partnership does not replace their work.
Assessment: the revised essay scored on the same rubric, plus a short reflection in which students name one change they made and why.
3. How would you measure growth in conventions without giving a grammar test?
Read the worked answer
Use the students' own writing before and after, with a measure that is specific enough to show change.
Sentence-boundary error count per 100 words. Count run-ons, fragments, and comma splices in the first draft and the revision of the same piece. This is objective, quick, and tied to the actual problem the four students have. A drop from six errors to two on the same assignment is meaningful growth, even if the essay is not yet perfect.
Focused rubric strand. Score conventions on the district rubric for both drafts, but report the strand separately so it is not averaged away by strong ideas.
Targeted editing task. Give a short passage with several boundary errors and ask students to fix and explain two. This checks whether they can apply the rule to unfamiliar text, which a workbook drill does not.
I would not use a comma-rule test because it measures labeling, not writing. The goal is that students stop producing run-ons in their own essays, and the before-and-after count is the closest evidence of that. For the class as a whole, I would also track organization scores across the two essays, since that was the larger instructional target.
