FAQs
How do I teach students to identify and fix run-on sentences?
Start by helping students understand what an independent clause is and how two independent clauses must be properly joined using a period, semicolon, coordinating conjunction, or subordinating conjunction. A common classroom strategy is to have students read sentences aloud — run-ons often reveal themselves when a sentence feels breathless or overly long. From there, practice should focus on recognizing the error pattern first, then applying the appropriate correction method, since students who can only fix run-ons with periods often struggle when a conjunction would be more stylistically appropriate.
What exercises help students practice correcting run-on sentences?
Effective practice exercises include identifying whether a given sentence is correct or a run-on, rewriting run-ons using multiple correction strategies, and combining short choppy sentences into properly punctuated compound or complex sentences. Exercises that present the same run-on error and ask students to fix it three different ways are especially valuable because they reinforce that there is no single correct fix — only grammatically valid options. Worksheets with targeted practice problems and answer keys allow students to self-check and build independence.
What mistakes do students commonly make when correcting run-on sentences?
The most frequent error is the comma splice — students insert a comma between two independent clauses thinking it resolves the run-on, but a comma alone is not sufficient without a coordinating conjunction. Students also tend to default to adding a period as the only correction strategy, missing opportunities to use semicolons or subordinating conjunctions that would better show the relationship between ideas. Another common misconception is confusing long sentences with run-on sentences — length alone does not make a sentence a run-on; the issue is the absence of proper grammatical connection between independent clauses.
How can I differentiate run-on sentence practice for students at different skill levels?
For struggling students, begin with two-clause run-ons and limit correction choices to periods and coordinating conjunctions before introducing semicolons or subordination. More advanced students can work with multi-clause run-ons and practice selecting the correction method that best preserves the intended meaning of the original sentence. On Wayground, teachers can apply accommodations such as reduced answer choices or read-aloud support to individual students, which reduces cognitive load and makes differentiation manageable without creating entirely separate assignments.

Each worksheet includes a complete answer key, so students can self-correct and teachers can use results to inform targeted reteaching.
How is a run-on sentence different from a comma splice?
A run-on sentence is a broad term for any sentence in which two or more independent clauses are joined without proper punctuation or conjunctions, while a comma splice is a specific type of run-on where only a comma — without a coordinating conjunction — is used to connect those clauses. Teaching this distinction matters because students who understand comma splices as a subcategory of run-ons are better equipped to self-edit their own writing. Both errors are addressed through the same set of correction strategies: adding a period, using a semicolon, or joining clauses with an appropriate conjunction.
