Run On Sentences Practice Activities
Grade 5 students practice finding and fixing run-on sentences by separating complete thoughts and adding correct punctuation or conjunctions.
Practice that builds confidence
What students learn
These Grade 5 grammar worksheets help students recognize run-on sentences, including fused sentences and comma splices. Children practise deciding where one complete thought ends and another begins, then revise the sentence so the meaning is clear.
The printable activities include identification, correction, and sentence-rewriting tasks. Students work with periods, commas with coordinating conjunctions, and other clear ways to join or separate related ideas in the sentence strand.
Run-on sentences happen when two or more complete thoughts are pushed together without the right punctuation or joining word. In Grade 5, students are ready to move beyond “make it shorter” and explain why a sentence needs a break. They learn to spot a subject and predicate in each complete thought, then choose a correction that keeps the writer’s meaning.
How the practice progresses
The worksheets begin with clear examples such as two complete sentences joined with no punctuation. Students then meet comma splices, where a comma is used but is not strong enough by itself. Later tasks ask them to rewrite sentences using a period, a comma plus a coordinating conjunction such as and, but, or so, or a more careful revision that changes the sentence structure.
A simple parent routine
At home, ask your child to read each sentence aloud and pause where the idea feels finished. Have them underline the first complete thought once and the second complete thought twice. Then ask, “Should these be two sentences, or should they be connected?” This quick routine turns correction into a decision, not a guessing game. After the worksheet, invite your child to find one run-on in their own writing and revise it.
Classroom uses
Teachers can use these pages for sentence mini-lessons, grammar centers, morning work, or targeted writing conferences. One useful routine is to display a run-on sentence, let students propose two different corrections, and compare how punctuation changes the rhythm. The worksheets also pair well with paragraph revision because students can apply the same skill to drafts.
Common errors to watch for
Students may add a comma between two complete sentences and think the problem is fixed. Others may split a sentence fragment away from the complete sentence, creating a new error. Watch for corrections that change the meaning, remove important details, or overuse and. Encourage students to check that every revised sentence can stand on its own or is joined correctly.

Helpful answers
Frequently asked questions
What is a run-on sentence in Grade 5 grammar?
A run-on sentence joins two or more complete thoughts without correct punctuation or a proper joining word. Grade 5 students usually learn to identify both complete thoughts and revise the sentence clearly.
Do these worksheets include comma splices?
Yes. Students practise noticing when two complete sentences are joined by only a comma and learn to fix the error with a period, a comma plus a conjunction, or a better revision.
How can my child check whether a sentence is a run-on?
Have your child look for two subjects and two predicates that each express a complete thought. If both parts could stand alone but are not joined correctly, the sentence is likely a run-on.
What corrections should Grade 5 students use?
Common corrections include splitting the run-on into two sentences, adding a comma with a coordinating conjunction, or rewriting the sentence so one idea is clearly connected to the other.
Can these worksheets help with paragraph writing?
Yes. Once students can fix run-ons in isolated sentences, they can use the same strategy to revise personal narratives, opinion paragraphs, reports, and other Grade 5 writing.
