Words to know

what the subject does or is
a meaning that makes sense on its own
1. Discover: The dog barked
The dog barked. The small dog barked loudly. The small dog in the yard barked loudly at the cat. Each sentence is complete, and each one tells more.
Think: Who is the sentence about? What does the subject do?
2. Understand: Building a simple sentence
Idea 1: Subject and predicate
Every sentence has a subject (who or what) and a predicate (what it does or is): The dog | barked.
Idea 2: Complete thought
A sentence gives a complete thought. It begins with a capital letter and ends with a full stop, question mark or exclamation mark.
Idea 3: Expanding
You can add adjectives, adverbs and prepositional phrases: The small dog in the yard barked loudly.
3. Worked examples
Example 1 (I show you): Subject
What is the subject of The dog barked?
- Who?
Answer: The dog
Example 2 (We do it together): Predicate
What is the predicate?
- What did it do?
Answer: barked
Example 3 (You try): Expand
Expand it with an adjective.
Show the steps and answer
- Add small.
Answer: The small dog barked.
Did you know?

Why this matters

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.
