1. What is a compound sentence?
A compound sentence is made up of two or more independent clauses or simple sentences.
Formula IC+IC=CS
Remember
Each clause must have a S & V
Each clause must be independent = makes a complete thought
Each clause may have compound S & V’s
There may be more than two clauses

2. There are two ways to form compound sentences…
Independent clauses can be joined using a comma and a coordinating conjunction.
Coordinating Conjunctions = For, And, Nor, But, Or, Yet, So
(Also known as FANBOYS)
Examples:
Sally wrote about frogs. Leroy read about lizards.
Sally wrote about frogs, and Leroy read about lizards.
Suzy turned her work in on time. Larry asked for an extension.
Suzy turned her work in on time, but Larry asked for an extension.
Sue worked hard on her project. Lou earned a higher grade.
Sue worked hard on her project, yet Lou earned a higher grade.

3. Remember….
In order to be a compound sentence, the sentence must have two or more independent clauses. Each independent clause must have its own subject and predicate.
Which is compound?????
Kim and Maureen read each other’s stories, and they gave each other suggestion for improvements.
Kim and Maureen read each other’s stories and made suggestions for improvements.

4. Practice Time….
Identify the S and V in each of the following. Two sentences are NOT compound….
Can you locate them?
Mom was planning a trip, and I helped her.
Mom and I found a location and planned a trip.
Mom chose Chicago, so I started to make plans.
Mom read about many activities, but we couldn’t participate in all of them.
We studied the choices for a long time, yet we could not make a decision.
Mom talked to dad and finally made a decision about her plans.

5. Practice Time….(cont.)
Complete each sentence so that it is a compound sentence. Use the coordinating conjunction in parentheses.
His suggestion sounded good. (but)
Dad promised us a trip to Orlando. (and)
We must keep our expenses low. (or)
We planned very carefully. (yet)
We ended up saving money. (so)
Combine each pair to form a compound sentence. Only use each coordinating conjunction ONCE.
She instructed us. We started on our search.
We got back to the picnic. Someone had eaten all the food.
It was a beautiful day. We decided to go for a hike.
The farmer fixed the broken gate. The goat managed to escape.
We spent much time practicing. We plan to win the game.

6. A second way to form compound sentences…
Independent clauses can be joined using a semicolon
Use a ; to join independent clauses when they are NOT joined by a comma and conjunction.
Basically….the semicolon takes the place of the comma and conjunction
NEVER use both at the same time in a sentence!
FYI….the clauses must contain ideas that are closely related
Examples
Sally wrote about frogs. Leroy read about lizards.
Sally wrote about frogs; Leroy read about lizards.
Suzy turned her work in on time. Larry asked for an extension.
Suzy turned her work in on time; Larry asked for an extension.

7. Hmmmm….So what do you think?
I am so proud of my students this year; they have been working so hard on all tasks.
The school will host an open house next week; because many parents want to meet the new teachers.
The band played during halftime; the home team was leading by only a single point.
…which of the above is correctly written?
…which of the above contains ideas that aren’t closely related?
…which of above doesn’t contain two independent clauses?

8. Practice Time
We should be proud of inventions created over the years. The list is long and impressive.
Some things have been around for a long time. They were invented earlier than you may think.
The late 1870’s were very productive for America. The telephone and light bulb were invented in that period.
Now select and rewrite two of the above using a comma and conjunction to form the compound sentence.
FYI…one of them simply does NOT work with any of the coordinating conjunctions!
