Teach your students how to avoid run-on sentence with these worksheets they will enjoy them.

The following collection of activity sheets will present various run-on sentences. Students will be asked to correct them using one of the four different methods, either by adding their own punctuation, rewriting the sentences, or identifying which multiple-choice answer is correctly punctuated. Students will also be asked to determine whether a sentence is simple, compound, or run-on. Answer sheets have been provided for instructors, but please note that in some cases, your students' answers may vary.

An example of a run-on sentence would be: I am a boy I am lacrosse player. The reason this is incorrect is because there are basically two complete sentences fused into one. That's a reason that run-on sentences are called fused sentences.

How to Fix a Run-On Sentence

Brief, simple sentences throughout your article or essay can make it hard for the reader to stay focused. So, combining sentences can add to the sentence structure simply by adding some variety. However, you should be wary of this type of language. They can be confusing and hard to read –and even result in your writing becoming sloppy.

Let's take a closer look at how to fix run-on sentences and improve your writing skills.

What are They?

First, let's learn what exactly they are. This grammar mistake occurs when two or more distinct clauses are incorrectly used in one sentence. It can become hard to read for the people and become distracting too. As a writer, you need to avoid them to make sure that you are communicating the intended idea and key information smoothly.

A common kind of run-on sentence involves the comma splice. This occurs when you use a comma to join two different clauses together.

How to Fix Them

Run-on sentences can be corrected by different grammar tools. You need to connect the two clauses naturally. Here are some ways to do that:

Using Periods

One of the easiest ways to split the run-on sentence is to use a period to create smaller sentences. This works best with longer sentences that can contain too much information. One way to determine whether your sentence is too long and in need of a period is to read it aloud. If you feel like you are running out of breath, you have your answer.

Use the period to break the sentence. However, make sure that it doesn't result in choppy, short sentences.

For example:

Error: "Adam and Jane planned to go to school starting from Thursday because they thought that their mother wouldn't be able to come home in time after the holidays, but then their mother called them and told them that she booked a flight to come home in time for their school."

Corrected Version: "Adam and Jane planned to go to school starting from Thursday because they thought that their mother wouldn't be able to come home in time after the holidays. However, their mother called and told them that she booked a flight to come home in time for their school."

Using a Semicolon

You can use a semicolon between two different clauses to fix the run-on sentence. It is definitely a stylish way to help you establish a connection between the sentences.

Error: "Diana was looking at five different colleges to apply for her degree from all over the country, but she missed the deadline for two, so she only ended up applying to three from her original list."

Corrected Version: "Diana was looking at five different colleges to apply for her degree from all over the country; she missed the deadline for two, so she only ended up applying to three from her original list."

Using Commas or Coordinating Conjunctions

You can use a comma and pair it with coordinating conjunctions like "or,","bu,t" or "and." You can use this method to establish that there is a connection between the two independent clauses.

Error: "I am going to go to school from August; Jane is going from September."

Corrected Version: "I am going to go to school from August, but Jane is going from September."

Using Subordinating Conjunctions

You can take an independent clause and change it to a dependent one by using subordinating conjunctions like "although," "unless," or "because." It creates a complex sentence while cementing the link between the two sentence parts. It can also improve the flow between the two clauses.

Error: "I like working at the Cheesecake factory; they have great discounts for employees."

Corrected Version: "I like working at the Cheesecake factory because they have great discounts for employees."

Now that you know how to fix this type of language, you can use the techniques above to improve your writing skills.
