Student lesson

The lesson in 60 seconds

1. Discover: Ama’s notes

Ama writes: Running down the road. Her teacher asks, Who was running? Ama fixes it: The boy was running down the road. Another note: The big red bus. The teacher asks, What about the bus? Ama writes: The big red bus stopped.

Think: Why were the first versions not sentences?

2. Understand: Fixing incomplete sentences

Idea 1: What is a fragment?

A fragment is part of a sentence that does not make a complete thought: Running down the road. (no subject)

Idea 2: Missing parts

The big red bus. has a subject but a missing verb. Running down the road. has a missing subject.

Idea 3: Fix

Add the missing part so it becomes a complete sentence. Read it aloud: does it make sense by itself?

Remember: A fragment lacks a subject, a verb or a complete thought; add what is missing.

3. Worked examples

Example 1 (I show you): Spot

Is Running down the road. a sentence?

  1. Who runs?

Answer: no, it is a fragment

Example 2 (We do it together): Fix

Fix The big red bus.

  1. Add a verb.

Answer: The big red bus stopped.

Example 3 (You try): Check

How can you check?

Show the steps and answer
  1. Read aloud.

Answer: ask if it makes a complete thought

Did you know?

Writers sometimes use fragments on purpose in stories, but in school writing we use full sentences.

Why this matters

Complete sentences help the reader understand your ideas.

4. Explore: Fragment fixer

Fix fragments.

  1. Write four fragments.
  2. Find what is missing.
  3. Rewrite them.
  4. Read aloud.
Think about it: what did you notice?

You can fix fragments.

Say it in a sentence

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

  • This is a fragment because ___.
  • It is missing a ___.
  • The fixed sentence is ___.

Mastery and remediation

Objective Bronze (Developing) Silver (Proficient) Gold (Advanced)
O1 Define a fragment 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 Spot missing subjects or verbs 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 Fix fragments 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.
