Student lesson
- Write two independent clauses.
- Add a dependent clause.
- Punctuate.
- Check clarity.
Words to know
two or more independent clauses plus at least one dependent clause
being easy to understand
joining equal clauses
making one clause depend on another
1. Discover: Long but clear
Kofi writes: “Although the road was flooded, the bus driver turned back, and the passengers waited for the water to drop.” The dependent clause although the road was flooded plus two independent clauses make a compound-complex sentence.
It uses subordination (although) and coordination (and). But long sentences can lose clarity, so Kofi checks every part and splits if needed.
Think: When is a long sentence too long?
2. Understand: Long sentences done well
Idea 1: Structure
A compound-complex sentence has two independent clauses and a dependent clause.
Idea 2: Coordination and subordination
Use coordination to join equals and subordination to add detail.
Idea 3: Clarity
Always check clarity. If it is confusing, split it.
3. Worked examples
Example 1 (I show you): Dependent
Which is the dependent clause?
- Although the road was flooded.
Answer: although the road was flooded
Example 2 (We do it together): Independent
Name one independent clause.
- The bus driver turned back.
Answer: the bus driver turned back
Example 3 (You try): Clarity
What to do if confusing?
Show the steps and answer
- Split.
Answer: split it into shorter sentences
Did you know?
Great writers mix long, balanced sentences with very short ones.
Why this matters
Compound-complex sentences let you pack ideas while staying clear.

|---|---|---|---|
| O1 Identify the parts | 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 Build a compound-complex sentence | 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 |
| O3 Punctuate it | 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 |

If a learner struggles
- Find the misconception: Rushing without checking. Slow down and check your work.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Re-read the examples slowly and use the sentence frames.
- Guided practice: work through one example together and let the learner try the next one.
- Reassess: use the quiz again or the worksheet.
- 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: identify the parts; build a compound-complex sentence; punctuate it; judge clarity.
Prerequisite knowledge. Complex sentences.
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.

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.
