Read each sentence carefully. A run-on sentence is when two or more complete sentences are joined together without the correct punctuation or connecting words. We will practice fixing them!

Read each sentence. Is it a run-on sentence? Circle T for True (it is a run-on) or F for False (it is not a run-on).

1. The dog barked loudly the cat ran away.

True

False

2. I like to read books they are fun.

True

False

3. The sun is bright.

True

False

Rewrite each run-on sentence correctly. You can use a period to make two sentences, or a comma and a connecting word (like 'and', 'but', or 'so').

1. My brother loves to play soccer he is very good at it.

2. We went to the park we played on the swings.

3. The girl was hungry she ate a big sandwich.

Write two sentences. The first sentence should be a run-on sentence. The second sentence should be the corrected version of your run-on sentence.
