Simple Sentence Diagramming

Sentence diagramming can be a useful tool to make the abstract components of English grammar more concrete. Most students find that the visual image helps them better understand and remember grammatical terms, the parts of a sentence, and the basic rules of grammar. With practice, writers can use diagramming to diagnose their own grammatical errors and fix them.

Teaching Grammar and Mechanics Programs

Teaching Grammar and Mechanics

My Teaching Grammar and Mechanics Grades 4, 5, 6, 7, 8, and High School programs include a simple sentence diagram for each lesson (plus a mentor text, error analysis, practice in the writing context, and a formative assessment). The sentence diagrams are “simple,” because instead of requiring students to construct the entire diagram of a given sentence from scratch (takes too much class time), the simple sentence diagrams provide the drawing (the lines) and the words of the sentence that are not the focus of the grammar lesson.

Check out how much students can learn about grammar with these two simple sentence diagrams from my programs. Both examples focus on adverbs.

Simple Sentence Diagram Examples


Lesson Focus: An adverb can modify a verb and answer How? An adverb may be placed before or after the verb that it modifies. Modifies means to identify, define, describe, or limit. Examples: Carefully she answered. He walked slowly.

Complete the sentence diagram for this sentence: They happily played video games.



Compare your diagram to that on the display. Use a different color pen or pencil to place a √ above each correctly placed answer and change any errors.




Happily, they played video games. They happily played video games. They played video games happily.


Lesson Focus: Today we are studying adverb order. Remember that an adverb modifies a verb, an adjective, or another adverb and can be a word or a phrase. When using more than one adverb to modify the same part of speech, usually place adverbs in this functional order: 1. What degree 2. How 3. Where 4. When. Example: She sings more enthusiastically on the stage each night.

Revise and complete the sentence diagram for this mixed-up sentence: “The track star runs quickly now.”





Compare your diagram to that on the display. Use a different color pen or pencil to place a check mark √ above each correctly placed answer and revise any errors.






The track star runs quickly now.

Whether you choose to include simple sentence diagramming as one instructional component of teaching grammar and usage in the reading and writing contexts, the following three 10-minute lessons will help your students better understand how sentences are structured.
