the independent clause in a sentence
fronted clause
a subordinate clause placed first

1. Discover: Adding detail

Zainab writes: “We ate when the rain stopped.” (time) “She stayed home because she was ill.” (cause) “If you study, you will pass.” (condition) “Although he was tired, he finished.” (contrast)

When the subordinate clause comes first (a fronted clause), a comma follows it. When it follows the main clause, no comma is usually needed. A relative clause: The runner who won was Ola.

Think: Where does the comma go?

2. Understand: Detail with subordinate clauses

Idea 1: Subordinate clauses

A subordinate clause adds time, cause, condition or contrast to the main clause.

Idea 2: Comma rule

After a fronted clause, use a comma. After the main clause, usually none.

Idea 3: Relative clauses

A relative clause adds detail about a noun: who, which, that.

Remember: Complex sentences add detail with subordinate and relative clauses; comma after a fronted clause.

3. Worked examples

Example 1 (I show you): Time

Which clause shows time?

  1. When the rain stopped.

Answer: when the rain stopped

Example 2 (We do it together): Comma

Where is the comma?

  1. After fronted clause.

Answer: after a fronted clause

Example 3 (You try): Relative

Which is a relative clause?

Show the steps and answer
  1. Who won.

Answer: who won

Did you know?

Moving a clause to the front changes emphasis without changing the facts.

Why this matters

Complex sentences express relationships between ideas.

4. Explore: Clause play

Write complex sentences.

  1. Write a main clause.
  2. Add time, cause, condition and contrast clauses.
  3. Try front and back positions.
  4. Add commas.
Think about it: what did you notice?

You can write complex sentences.

O1 Use subordinators Shows this with help from an adult or a picture Does this independently and explains how they know Explains it clearly and uses it in a new situation
O2 Punctuate clause order Shows this with help from an adult or a picture Does this independently and explains how they know Explains it clearly and uses it in a new situation

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.
