Student lesson

The lesson in 60 seconds

  1. Find the verb.
  2. Find who or what does it.
  3. Check it is complete.
  4. Fix fragments and run-ons.

Words to know

subject
who or what the sentence is about
predicate
the part that says what the subject does or is
object
the person or thing that receives the action
fragment
an incomplete sentence

1. Discover: Building sentences

Dayo writes: The farmer sold mangoes. Subject: The farmer. Predicate: sold mangoes. Object: mangoes. He writes The mangoes were sweet. where sweet is a complement describing the subject.

He spots a fragment: Because the road was long. It is incomplete. He fixes it: Because the road was long, they rested.

Think: What does a complete sentence need?

2. Understand: What makes a sentence

Idea 1: Subject and predicate

A complete sentence has a subject and a predicate with a main verb.

Idea 2: Object and complement

An object receives the action (sold mangoes). A complement completes the meaning (were sweet).

Idea 3: Fragments and run-ons

A fragment lacks a main clause. A run-on joins sentences without correct punctuation. Fix both.

Remember: A complete sentence has a subject and predicate; fix fragments and run-ons.

3. Worked examples

Example 1 (I show you): Subject

What is the subject?

  1. Who.

Answer: the farmer

Example 2 (We do it together): Object

What is the object?

  1. What was sold.

Answer: mangoes

Example 3 (You try): Fix

How do you fix the fragment?

Show the steps and answer
  1. Add a main clause.

Answer: add a main clause such as they rested

Did you know?

The shortest complete sentence can be a single word, such as Go!

Why this matters

Strong sentence structure makes writing clear.

4. Explore: Build and fix

Fix sentences.

  1. Write five sentences.
  2. Underline subject and predicate.
  3. Find one fragment.
  4. Fix it.
Think about it: what did you notice?

You can build sentences.

Mastery and remediation

Objective Bronze (Developing) Silver (Proficient) Gold (Advanced)
O1 Identify subject and predicate 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 Identify objects 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 Identify complements 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
O4 Fix fragments and run-ons 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.

Lesson objectives. Learners will: identify subject and predicate; identify objects; identify complements; fix fragments and run-ons.

Prerequisite knowledge. Academic writing vocabulary.

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.

6–9. Teaching procedure, explanation notes, guided and independent activities

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.
