**National Punctuation Day (Sept 24): Punctuation Detectives** Work with your team to solve the “Missing Muffin” case by spotting punctuation clues, choosing the best punctuation, and revising dialogue. **Team directions (40–60 minutes):** 1) Pick roles: Reader (reads aloud), Scribe (types), Rule-Keeper (checks punctuation rules), Checker (confirms final answers). 2) Read *Exhibit A* aloud once before answering. 3) Discuss each question for 30–60 seconds, then the Scribe submits. 4) For the final revision, aim for clarity first (sentence endings), then dialogue punctuation, then commas/colons/semicolons, then apostrophes. Be ready to justify your choices with a rule, not just a “gut feeling.”
National Punctuation Day (Sept 24) — Case File #024: The Missing Muffin
You and your team are the Punctuation Detectives at Midtown Middle. Someone stole the cafeteria’s prized Blueberry Mega Muffin and left behind a “witness statement.”
Your mission: Find punctuation clues, choose the best punctuation, and revise the statement so it’s clear.
I was walking past the cafeteria at 12 10 when I heard someone whisper dont look back
Then I saw Coach Rivera holding a tray he said I didnt take it
The sign by the muffins said todays special blueberry mega muffin only 2 dollars
I asked who took it and the voice said maybe it was the principal maybe it was the cat
Before I could ask more the lights flickered and someone yelled stop
I wrote down three clues a crumb trail a note that read meet me after school and a key
Case closed maybe
