Lesson Content/Board Summary

Complex Sentence: Structure Of A Complex Sentence

What is a Complex Sentence?

A complex sentence is a sentence that contains one independent (main) clause and at least one dependent (subordinate) clause. It expresses a complete thought while also including additional information that relies on the main clause for its full meaning.

Independent (Main) Clause

An independent clause is a group of words that contains a subject and a verb and expresses a complete thought. It can stand alone as a simple sentence.

Examples of independent clauses:

1. She smiled.
2. The boy ran fast.
3. We will go to the market.

Dependent (Subordinate) Clause

A dependent clause is a group of words that contains a subject and a verb but does not express a complete thought. It cannot stand alone as a sentence. Dependent clauses often begin with subordinating conjunctions or relative pronouns.

Examples of subordinating conjunctions:

1. Because
2. Although
3. While
4. If
5. When
6. Since
7. Unless
8. Before
9. After
10. As

Examples of dependent clauses (cannot stand alone):

1. Because he was tired
2. Although it was raining
3. When she arrived
4. If you study hard

Structure of a Complex Sentence

A complex sentence is formed by combining an independent clause with one or more dependent clauses. The dependent clause adds more information to the independent clause, such as a reason, condition, time, or contrast.

There are two common structures:

1. Independent Clause + Dependent Clause: When the independent clause comes first, a comma is usually not needed unless the dependent clause is non-essential.
2. Dependent Clause + Independent Clause: When the dependent clause comes first, it is usually followed by a comma before the independent clause.

Examples of Complex Sentences

Here are examples illustrating the structure:

1. Because he was tired, he went to bed early.
   • Dependent Clause: “Because he was tired”
   • Independent Clause: “he went to bed early”
2. She passed the exam because she studied hard.
   • Independent Clause: “She passed the exam”
   • Dependent Clause: “because she studied hard”
3. Although it was raining, they decided to play football.
   • Dependent Clause: “Although it was raining”
   • Independent Clause: “they decided to play football”
4. We will visit the museum when we go to Abuja.
   • Independent Clause: “We will visit the museum”
   • Dependent Clause: “when we go to Abuja”
5. If you finish your homework, you can watch TV.
   • Dependent Clause: “If you finish your homework”
   • Independent Clause: “you can watch TV”
6. The dog barked loudly while the mailman delivered the letters.
   • Independent Clause: “The dog barked loudly”
   • Dependent Clause: “while the mailman delivered the letters”

Instructional Procedures

Step 1: Introduction

Time: 5 minutes

Teaching Skill: Review/Engage

Teacher’s Activity: The teacher greets the students and reviews previous knowledge on simple and compound sentences, asking students to give examples of each. The teacher then introduces the topic of complex sentences as a way to express more detailed ideas.

Pupils’ Activity: Pupils respond to questions about simple and compound sentences and listen attentively to the introduction of the new topic.

Learning Point: Prior sentence knowledge activated

Step 2: Defining Complex Sentences

Time: 10 minutes

Teaching Skill: Explanation/Definition

Teacher’s Activity: The teacher explains what a complex sentence is, highlighting that it contains one independent clause and at least one dependent clause. The teacher provides a simple example and writes it on the board.

Pupils’ Activity: Pupils listen, ask questions for clarification, and copy the definition and example into their notebooks.

Learning Point: Complex sentence definition

Step 3: Understanding Independent Clauses

Time: 10 minutes

Teaching Skill: Explanation/Illustration

Teacher’s Activity: The teacher explains the concept of an independent (main) clause, emphasizing that it can stand alone as a complete sentence. The teacher provides several examples and asks students to identify the subject and verb in each.

Pupils’ Activity: Pupils listen, identify subjects and verbs in examples, and contribute their own examples of independent clauses.

Learning Point: Independent clause characteristics

Step 4: Understanding Dependent Clauses

Time: 10 minutes

Teaching Skill: Explanation/Categorisation

Teacher’s Activity: The teacher explains what a dependent (subordinate) clause is, stressing that it cannot stand alone and often begins with a subordinating conjunction. The teacher lists common subordinating conjunctions and provides examples of dependent clauses.

Pupils’ Activity: Pupils listen, note down subordinating conjunctions, and identify why dependent clauses cannot stand alone.

Learning Point: Dependent clause identification

Step 5: Combining Clauses to Form Complex Sentences

Time: 10 minutes

Teaching Skill: Demonstration/Application

Teacher’s Activity: The teacher demonstrates how to combine independent and dependent clauses to form complex sentences, showing both structures (independent + dependent, and dependent + independent with a comma). The teacher provides several clear examples and explains the role of subordinating conjunctions.

Pupils’ Activity: Pupils observe the examples, ask questions about comma usage, and practice forming simple complex sentences orally.

Learning Point: Complex sentence formation

Step 6: Guided Practice with Online Quizzes

Time: 5 minutes

Teaching Skill: Facilitation/Guided Practice

Teacher’s Activity: The teacher guides students to take online quizzes on complex sentences, either individually or in pairs, using available devices or by projecting the quiz for whole-class participation. The teacher provides support and clarifies any difficulties.

Pupils’ Activity: Pupils actively participate in the online quizzes, identifying complex sentences and their components, and discussing answers with peers.
