Lesson Overview
Sentence Structure
A sentence is a group of words that expresses a complete thought. Every sentence must begin with a capital letter and end with a punctuation mark. A period (.) ends a sentence that makes a statement. A question mark (?) ends a sentence that asks a question. An exclamation point (!) ends a sentence that shows excitement.
Every sentence has two parts: a subject and a predicate. The subject contains the main noun and tells who or what the sentence is about. The predicate tells what the subject is doing and contains the verb. In Ashley walks to the park, Ashley is the subject and walks to the park is the predicate.
There are three types of sentences students use every day. A declarative sentence makes a statement: Tom goes to school. An interrogative sentence asks a question: Did Tom go to school? An imperative sentence makes a request or gives a command: Hurry Tom! Go to school now! The practice worksheet has students classify sentences by type and identify subjects and predicates.
How to Use This Lesson
1. Use the teacher lesson plan (pages 1–3) to introduce sentence structure. Write example sentences on the board and ask students to identify which are complete sentences and why.
2. Distribute the student copy (page 4). Students review the definitions of subject, predicate, and the three sentence types.
3. Distribute the practice worksheet (pages 5–6). Part 1: classify each sentence as declarative, interrogative, or imperative. Part 2: underline the subject once and the predicate twice. Review using the answer key.
