Fix Run On Sentences With And, But or So
Written by Adi Ackerman, Head Teacher
"Fix Run On Sentences With And, But or So" is written for 3rd Grade (Ages 8-9), and it covers Common Core L.3.1.I. If your little one is a year younger but already steady on parts of speech, the page still works. You may just need to read the instructions out loud. And if they are older and coordinating conjunctions never quite stuck, this is a short review rather than busywork.

How do I use this coordinating conjunctions worksheet?

Ask how the two ideas fit: same idea means and, opposite means but, result means so. Remind your child that the comma goes before the conjunction. Check with the answer key.
What does this worksheet teach?
⌄
Fix seven run on sentences with a comma and and, but or so, using clues for same, opposite or result. A run on sentence joins two sentences with no joining word. A coordinating conjunction like and, but or so can fix it. The directions on the page read: Read each run on sentence and its clue. Then, write it as one sentence with a comma and and, but or so. An answer key is included.
Can I use this coordinating conjunctions worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 3rd Grade parts of speech, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with coordinating conjunctions. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.
What are the seven coordinating conjunctions and what does each express?
⌄
The FANBOYS conjunctions are: For (reason), And (addition), Nor (negative addition), But (contrast), Or (choice), Yet (unexpected contrast), and So (result) - 3rd graders learn these through sentence practice.
How do coordinating conjunctions help 3rd graders write compound sentences?
⌄
A coordinating conjunction placed between two complete sentences (with a comma before it) combines them into a compound sentence - a key sentence structure 3rd graders are expected to produce in writing.
What mistakes do 3rd graders commonly make with coordinating conjunctions?
⌄
Students often forget the comma before the conjunction in a compound sentence, or use 'and' for every connection instead of choosing the conjunction that best fits the relationship between ideas.
How many 3rd Grade coordinating conjunctions worksheets are there?
⌄

What age are coordinating conjunctions worksheets for?
⌄
These are written for 3rd Grade students, roughly ages 8-9. Many teachers also use them a grade up for review or a grade down as an extension, so use the preview to judge the fit for a particular child.
Are these coordinating conjunctions worksheets aligned to Common Core?
⌄
Yes. Each one shows the Common Core code it covers on its own page, so you can check the alignment yourself rather than taking our word for it.
