Student lesson

The lesson in 60 seconds

  1. Choose the relationship.
  2. Pick the conjunction.
  3. Join the clauses.
  4. Use a comma if the subordinate clause starts the sentence.

Words to know

subordinating conjunction
a word that begins a dependent clause, such as because or although
dependent clause
a clause that cannot stand alone
independent clause
a clause that can stand alone
condition
what must be true for something to happen

1. Discover: Time, reason, condition

Tola writes: We stayed inside because it was raining. When the rain stopped, we went out. If the pitch is dry, we will play. Although it was cold, we enjoyed the match. She notices that because it was raining cannot stand alone.

Think: Where did she put commas?

2. Understand: Because, when, if, although

Idea 1: What they show

Subordinating conjunctions show time (when, after, while, before), reason (because, since), condition (if, unless) and contrast (although, whereas).

Idea 2: Dependent clauses

A dependent clause starts with one and cannot stand alone. It needs an independent clause.

Idea 3: Comma rule

When the dependent clause comes first, use a comma: When the rain stopped, we went out. When it comes second, no comma is needed.

Remember: Subordinating conjunctions start dependent clauses that show time, reason, condition or contrast; comma if the clause comes first.

3. Worked examples

Example 1 (I show you): Reason

Which word shows a reason?

  1. Why?

Answer: because

Example 2 (We do it together): Condition

Which word shows a condition?

  1. What must be true?

Answer: if

Example 3 (You try): Comma

Punctuate: When the rain stopped we went out.

Show the steps and answer
  1. Dependent first.

Answer: When the rain stopped, we went out.

Did you know?

Sentences with subordinate clauses let writers show how ideas connect, not only that they follow each other.

Why this matters

Subordinating conjunctions make writing more sophisticated and clear.

4. Explore: Because, if, although

Write complex sentences.

  1. Write six pairs of ideas.
  2. Join each with a subordinating word.
  3. Move the clause to the start.
  4. Add commas.
Think about it: what did you notice?

You can use subordinating conjunctions.

5. Practise

Say it in a sentence

Use these starters when you talk about the lesson. Say them out loud.

  • Because ___, ___.
  • When ___, ___.
  • If ___, ___.
  • Although ___, ___.

Courseversity badge thresholds (overall quiz score): Gold = 90–100%; Silver = 80–89.9%; Bronze = 70–79.9%. A badge is never a full record of progress.

If a learner struggles

  1. Find the misconception: Rushing without checking. Slow down and check your work.
  2. Explain another way: use real objects, pictures or actions first, then words.
  3. Show a simpler example: Re-read the examples slowly and use the sentence frames.
  4. Guided practice: work through one example together and let the learner try the next one.
  5. Reassess: use the quiz again or the worksheet.
  6. Move on when the learner shows Silver-level evidence independently.

For parents and guardians

In this lesson your child practises a key Grade 3 English skill with clear examples and a quiz. You do not need to be an expert to help.

  • Listen while your child explains the idea.
  • Ask for one new example.
  • Praise effort and careful work.
  • Ask “how do you know?” after each answer, and listen.
  • Praise effort, not only right answers. Mistakes are how we learn.
  • Ten to fifteen minutes a day is better than one long session.

Lesson objectives. Learners will: name subordinating conjunctions; show time, reason and contrast; build sentences with them; punctuate correctly.

Prerequisite knowledge. Coordinating conjunctions.

Materials. Chart paper or board, pencils, picture or word cards, a reading book if available. Low-resource options: use chalk or charcoal on a board or wall, drawings in the sand, and objects from the classroom instead of printed materials.

Preparation. Write the key words and examples on the board or on cards before the lesson.

Suggested duration. 45–60 minutes. It can be split into two shorter sessions.

Introduction (5 min). Introduce the idea with the opening example.

Explanation (10 min). Teach the key words.

Guided activity (10 min). Practise together.

Independent activity (10 min). Check understanding with the quiz.

Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.

Key questions. What is the key idea? Can I give my own example?

Teacher explanation notes. Move from the spoken word to pictures and then to print. Read aloud often, point to the words, and let learners hear and say before they read and write.

10–12. Differentiation, formative assessment, common misconceptions

Support. Use the sentence frames and work with a partner. Extension. Create a harder example of your own.

Formative assessment. Listen to learners read and explain, ask “how do you know?”, and check the independent work.

Misconceptions. Rushing without checking. Slow down and check your work.
