Mixed Comma Rules Practice Worksheet — Grade 7
Grade 7 grammar worksheet for analyzing five comma rules — series, dates, addresses, introductory elements, compound sentences, and appositives.
Commas serve several distinct jobs in English sentences, and writers at every level benefit from knowing exactly which job a comma is doing in a given spot. This worksheet focuses on five rules — series commas, introductory elements, appositives, compound sentences, and dates and addresses — and asks Grade 7 students to name the rule, not just apply it mechanically. That analytical step is key: a student who can label each comma with a rule can also catch comma errors in their own writing. The sheet moves from recognition to application to original production, so it works best as a standalone review or as a capstone activity after a comma unit. An answer key is included for every section.
