Sentence Structure Basics

Overview

This 30-minute lesson introduces Year 7 students to the fundamental components of sentences: subjects, predicates, and objects. It offers a structured exploration of simple and compound sentences, developing pupils’ understanding of sentence construction as per the National Curriculum for England requirements in English: Writing - Vocabulary, grammar and punctuation (Years 7-9).

National Curriculum Links

• English Programme of Study: Years 7-9
  • Grammar and punctuation: Pupils should be taught to revise and further their knowledge of grammatical terms such as subjects, predicates, and objects.
  • Sentence structure: Pupils should practise using a range of sentence structures, including simple and compound sentences, to create coherent writing.
• Key Learning Objectives:
  • Identify and explain the functions of subjects, predicates, and objects in sentences.
  • Construct accurate simple and compound sentences.
  • Understand how sentence components affect meaning and clarity.

Learning Objectives

By the end of this lesson students will be able to:

1. Define and identify subjects, predicates, and objects within sentences.
2. Construct simple sentences (subject + predicate).
3. Construct compound sentences using coordinating conjunctions (and, but, or).
4. Analyse how varying sentence structure can affect communication.

Resources Needed

• Whiteboard or interactive board
• Printed sentence strips (individual clauses and conjunctions)
• Student exercise sheets
• Mini whiteboards and pens for each student
• Timer or stopwatch

Lesson Breakdown

1. Starter Activity (5 minutes)

Objective: Activate prior knowledge and get students thinking about sentence parts.

• Teacher writes a simple sentence on the board, e.g. “The cat sat.”
• Students answer: "Who or what is this sentence about?" (Subject)
• Teacher highlights subject, predicate, and introduces the term ‘object’ with a second example, e.g. "The cat chased the mouse."
• Quick paired discussion: identify subject, predicate, and object in the second sentence. Share answers aloud.

---

2. Explicit Teaching & Modelling (8 minutes)

Objective: Clearly explain components and sentence types; model sentence construction.

• Define the terms:
  • Subject: who or what the sentence is about
  • Predicate: what the subject does or is
  • Object: what/whom the action is done to (if applicable)
• Use a sentence diagram on the board to break down “The dog (subject) ate (predicate) the bone (object).”
• Introduce simple sentences: must have at least a subject and predicate.
• Introduce compound sentences: two simple sentences joined by coordinating conjunctions (FANBOYS: for, and, nor, but, or, yet, so).
• Model combining two simple sentences into a compound sentence: “The dog ate the bone, and the cat drank the milk.”

---

3. Guided Practice (10 minutes)

Objective: Practice identifying parts and constructing sentences with teacher support.

• Distribute sentence strips with subjects, predicates, and objects written separately (e.g., “Anna”, “loves”, “music”).

• In groups of 2, students sort strips into: subject, predicate, object.

• Next, students use strips to build:

  • A simple sentence (subject + predicate, optionally + object)
  • Then combine two simple sentences into a compound sentence using conjunction strips.

• Teacher circulates to give feedback and prompts:

  • “Which word shows who the sentence is about?”
  • “What part tells us what happened?”
  • “Can you try joining these two ideas with ‘but’ or ‘and’?”

• Volunteers share sentences with the class.

---

4. Independent Challenge (5 minutes)

Objective: Apply knowledge individually to demonstrate understanding.

• Hand out mini whiteboards and pens to each student.
• Prompt: “Write one simple sentence and then expand it by joining it to a second simple sentence to create a compound sentence. Underline the subject, circle the predicate, and highlight the object (if there is one).”
• Set timer for 3 minutes.
• After completion, randomly select two or three students to explain their sentence structure aloud.

---

5. Plenary & Assessment (2 minutes)

Objective: Check understanding and consolidate learning.

• Quick-fire quiz using thumbs up/down:
  • “Is a predicate always a verb?” (Thumbs up)
  • “Can a sentence have two subjects with one predicate?” (Thumbs down) — prompt about compound sentences vs. simple sentences.
• Invite one student to explain in their own words what a compound sentence is.
• Give positive verbal feedback highlighting progress with sentence construction.

---

Extension Ideas (For home or next lesson)

• Create a short paragraph using a mix of simple and compound sentences, labelling subjects, predicates, and objects.
• Explore complex sentences and subordinating conjunctions as a lead-in to next lesson.

---

Differentiation

• Support: Provide sentence strips with images for visual clues. Allow use of a sentence frame template.
• Challenge: Encourage use of a wider range of conjunctions, including those less common (e.g., ‘yet’, ‘so’). Ask students to explain how changing conjunctions alters the meaning.

---

Notes for Teachers

• Maintain an interactive and hands-on approach—young adolescents benefit from kinaesthetic and social learning opportunities in grammar lessons.
• Use continuous formative assessment by observing group work and plenary feedback to tailor upcoming lessons.
• Relate to students’ spoken language experience: prompt them to say sentences aloud before writing.

This lesson integrates crucial sentence structure foundations aligned with the National Curriculum expectations, ensuring students are prepared for more advanced grammar and composition tasks later in the unit and Key Stage 3.
