1. Four Types of Sentences
A sentence is a group of words that expresses a complete thought.
There are four types of sentences.
Every sentence begins with a capital letter and ends with a punctuation mark.

An exclamatory sentence shows strong feelings. It ends with an exclamation mark.

3. Four Types of Sentences
Practice:
Write an example of each type of sentence.
Be sure to start each sentence with a capital letter and use the correct ending punctuation.
Label each sentence with the type of sentence.

4. Complete Subjects and Predicates
Every sentence has a subject and a predicate.
The complete subject is made up of all the words that tell whom or what the sentence is about. It can be one word or more than one word.
The complete predicate is made up of all the words that tell what the subject does or is. A complete predicate can be one word or more than one word.

5. Complete Subjects and Predicates
Copy the example sentences. Underline the complete subject once. Underline the complete predicate twice.
The little brown puppy played with the cat.
They chased each other around the room.
The cat hid.

6. Simple Subjects and Predicates
The simple subject is the most important word in the complete subject. It tells exactly whom or what the sentence is about.
The simple predicate is the most important word in the complete predicate. It tells exactly what the subject does or is.

7. Simple Subjects and Predicates
The teacher reads the book.
The students liked the book about the giant.
They were laughing at the giant.

8. Subjects in Imperative Sentences
The subject of an imperative sentence is always you.
The word you is not stated directly, but is understood to be the subject.
(You) Clean your room.
(You) Please put the clothes in the wash.

9. Compound Subjects
A compound subject has two or more simple subjects that share the same predicate.
A conjunction is a word that joins words or groups of words. In a compound subject, the conjunction and or or joins the subjects.
If two related sentences have the same predicate, you can combine the sentences by joining the subjects with the conjunction and or or. The new sentence will have a compound subject.

10. Compound Subjects Underline the compound subject.
Boys and girls play soccer.
Dribbling, kicking and heading are soccer skills.
Forwards or midfielders can score.
Combine the two sentences to make a compound subject.
Parents cheer for the team. Coaches cheer for the team.

11. Compound Predicates
A compound predicate has two or more simple predicates that share the same subject.
The predicates are joined by the conjunction and or or.
If two related sentences have the same subject, you can combine the sentences by joining the predicates with the conjunction and or or. The new sentence will have a compound predicate.

12. Compound Predicates Underline the compound predicate.
They shoot and dribble the ball.
Players pass or shoot.
Combine the two sentences to make a sentence with a compound predicate.
The goalie blocks the shot. The goalie punts the ball.

13. Compound Sentences
A simple sentence has one subject and one predicate. It expresses one complete idea.
A compound sentence combines two simple sentences that have related ideas.
A conjunction (and, but, or or) joins the two sentences.
Always use a comma before the conjunction in a compound sentence.

14. Compound Sentences
Use and to join two related sentences that are alike in some way.
I like peanut butter, and I eat it every day.
Use but to join two related sentences that show a contrast.
I like peanut butter, but I do not like peanuts.
Use or to join two related sentences that show a choice.
I buy strawberry jam, or I use grape jam.

15. Complex Sentences
A complex sentence is made up of two related ideas joined by a subordinating conjunction.
Subordinating Conjunctions:
after, although, because, before, since, until, when, while

16. Complex Sentences
You can combine two sentences with related ideas to form a complex sentence.
The man eats dinner. He orders dessert.
The man eats dinner before he orders dessert.
Before he orders dessert, the man eats dinner.
When the first idea begins with a subordinating conjunction, a comma follows that idea.

17. Fragments and Run-ons
A fragment is an incomplete sentence. To correct a fragment, add the missing subject or predicate.
A run-on sentence is two sentences that run together. To correct a run-on sentence, write two separate sentences or write a compound sentence.
A run-on sentence with only a comma between the two sentences is called a comma splice. Correct a comma splice by writing a compound sentence or two separate sentences.

18. Fragments and Run-ons Add a subject or predicate to each example.
Eats spaghetti.
Bob and David.
Correct each run-on sentence or comma splice.
I like spaghetti he prefers pizza.
We ordered pizza they delivered it.
One pizza had extra cheese, the other one had sausage.
