Words to know
the smallest part of a word that has meaning
a word that can stand alone
words that share a root
to break into parts to understand
1. Discover: The long word
Zainab finds the word unbreakable. She breaks it up: un- (not) + break (root) + -able (can be). So unbreakable means cannot be broken. Her teacher shows another: disagreement = dis- + agree + -ment.
Think: How many morphemes are in unbreakable?
2. Understand: Taking words apart
Idea 1: Morphemes
A morpheme is the smallest part of a word with meaning. Unbreakable has three: un, break, able.
Idea 2: Base and family
A base word can stand alone. Words built on it form a word family: agree, disagree, agreement, agreeable.
Idea 3: Analyse
To analyse a word, find the root, then the prefix, then the suffix, and join the meanings.
3. Worked examples
Example 1 (I show you): Parts
Split unbreakable.
- Three parts.
Answer: un + break + able
Example 2 (We do it together): Meaning
What does unbreakable mean?
- Combine meanings.
Answer: cannot be broken
Example 3 (You try): Family
Name a word in the agree family.
Show the steps and answer
- Add affixes.
Answer: disagree (or agreement/agreeable)
Did you know?
The longest common English words are often just a small root with many affixes.
Why this matters
Word analysis lets you understand and spell long words.
4. Explore: Take it apart
Analyse five long words.
- Choose five long words.
- Split each into morphemes.
- Write each meaning.
- Make one new word from each.
Think about it: what did you notice?
You can analyse words.
5. Practise
Say it in a sentence
Use these starters when you talk about the lesson. Say them out loud.
- The root is ___.
- The prefix is ___ and means ___.
- The suffix is ___ and means ___.
- Together it means ___.

Mastery and remediation
| Objective | Bronze (Developing) | Silver (Proficient) | Gold (Advanced) |
|---|---|---|---|
| O1 Split words into morphemes | 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 Name prefix, root, suffix | 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 Explain meaning from 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 |
| O4 Build related words | 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
- 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.
