Inside the case file
Turn sentence editing into a case worth cracking. This printable Capitalization and Punctuation ELA Mystery transforms grammar practice into a Scoot-style detective investigation for Grades 3–6 classroom teachers, homeschoolers, and tutors. It drops straight into a grammar, writing, or back-to-school lesson and keeps students editing for a reason.
Students travel from card to card, choose the correctly capitalized and punctuated sentence each time, use their answers to eliminate suspects from the line-up, and race to crack the case — all while reinforcing the conventions that show up on every writing rubric. No apps, no prep, no fuss.

The Case
A classroom mystery is afoot, and the clues are hidden in the punctuation. Investigators have rounded up a line-up of suspects, but it's up to your students to uncover the truth. The only way to crack the case is to edit closely: every correctly fixed sentence is a clue that rules another suspect out, until just one remains.
How the ELA Mystery Works
Your students become Reading Detectives. Scoot-style, they move from card to card, choose the sentence with correct capitalization and punctuation, and record their answers to gather evidence. Each correct answer eliminates a suspect from the line-up, and the list shrinks until only the culprit remains.
