This collection of worksheets will teach your students how to diagram short sentences correctly.

When we come across a complex sentence, we will often want to diagram the sentence. This helps us understand the parts of speech and the grammatical tools that are present within the sentence. In order to diagram sentences correctly, students must have a good grasp of the parts of speech and their functions within a sentence. Fun Project Idea: Have your students team up and choose famous movie quotes, sentences from favorite books, or advertising slogans, then challenge other teams to diagram them.

The following activity sheets will help your students learn how to identify the most important parts of a sentence, and place them on diagrams depending on their roles within that sentence. Sentences range from very simple to slightly complex.
