Commas, Semicolons & Dashes: Punctuation Worksheet for Grades 4–8 (Upper Elementary & Middle School)

Instructions

Read the brief explanations of commas, semicolons, and dashes. Then, complete the exercises by inserting the correct punctuation mark in the blank spaces or by rewriting the sentences correctly.

Punctuation Guide

• Comma ( , ): Used to separate items in a list, to separate independent clauses when joined by a conjunction (for, and, nor, but, or, yet, so), to set off introductory phrases, and to set off non-essential information.
• Semicolon ( ; ): Used to connect two closely related independent clauses (sentences that could stand on their own). It is also used to separate items in a list when the items themselves contain commas.
• Dash ( — ): Used to indicate an abrupt change of thought, to set off a summary or explanation, or to add emphasis to a point.
