7th Grade Language Arts / Lesson 4: Diagramming Sentences

Diagramming Sentences

What is a Sentence Diagram ?


  • As you saw in the Brain Pop Movie a sentence diagram is a type graphic organizer that helps you see how the words in a sentence relate to one another.


Parts of a Sentence Diagram


  • A sentence diagram begins with a straight horizontal line called a base line.



Parts of a Sentence Diagram


  • The base line is then divided by a vertical line called a bar.



    1. Notice the bar extends through the base line.
    2. The purpose of the bar is to separate the subject and predicate of a sentence.


Parts of a Sentence Diagram


  • If a sentence contains a direct object, it is also placed on the base line.


  • It is separated from the subject and predicate by another vertical line.




    1. Notice this line does not extend through the base line.
    2. This line is placed on the predicate side of the diagram because objects always     complete the meaning of the verb!


Parts of a Sentence Diagram


  • The subject is placed on the base line to the left of the bar .


  • The predicate is placed on the baseline to the right of the bar.


  • The direct object is place on the predicate side of the baseline.





 
Example


  • Let's look at a real sentence and see how a sentence diagram works.

  • Ray tossed the football.


    "Ray" is the subject and tells who the sentence is about.

    "tossed" is the simple predicate and tells the action the subject (Ray) is doing.

    "football" is the direct object and completes the meaning of the verb (predicate).



Parts of Sentence Diagram - Modifiers


  • Modifiers (words that change the meaning of or describe another word) are placed under the base line, just below the word they modify.


Example


  • Let's look at our sentence and see how a modifier is added to a sentence diagram.

  • Ray tossed the football.


    "the" is a modifier. It is an definite object that modifies the direct object.


Parts of a Sentence Diagram - Indirect Objects


  • If a sentence contains an indirect object, it is place below the base line under the verb.
  • The indirect object is placed under the verb because it tells to whom or to what the action of the verb is given or done.


 
Example


  • Let's look at another sentence and see how it is diagrammed.

  • Ray tossed the football.


    "Ray" is the subject and tells who the sentence is about.

    "tossed" is the simple predicate and tells the action the subject (Ray) is doing.

    "football" is the direct object and completes the meaning of the verb (predicate).

    "Jim" is the indirect object which tells to whom the action of "tossed" is given."
