Teacher's field guide

What Students Need to Do: Students fix tricky punctuation and usage in sentences and drafts. When more than one form is accepted, they check a style guide and use one choice consistently.
What Mastery Looks Like: A student can replace a comma splice with a period or semicolon and explain why. They can decide whether a serial comma helps a list, then follow that choice across a paragraph.
Common Misconceptions: Students may treat every disputed comma as an error, or assume one style guide's choice applies everywhere. They may join two complete sentences with a comma and call it a style choice.
How to Assess It: Exit ticket: Edit 'The lab closed early, the results were incomplete. Bring pens, notebooks and folders.' Fix the error, then say whether you would add a comma before 'and' on a school flyer and why.

Lesson moves

Give pairs sentence strips with comma splices, correct semicolons, and optional serial commas; have them sort the strips and fix only actual errors.
Ask whether 'I invited my parents, Maya and Leo' names two or four guests; have students rewrite it to make each reading clear.
Run an editor relay: teams repair four comma splices and mark two serial-comma choices as optional, then compare reasons.
Have students edit a school club flyer listing supplies, choosing a serial-comma policy and applying it to every list.
