Student lesson
- Break the word into parts.
- Name each part.
- Find each part’s meaning.
- Combine meanings.
Words to know
the smallest part of a word with meaning
a word part that carries the core meaning
a prefix or suffix added to a base
an ending that changes tense or number
1. Discover: Building “unbelievably”
Biola breaks unbelievably into un + believe + able + ly. Base: believe. Prefix: un- (not). Suffixes: -able (can be) and -ly (in a way). Together: in a way that cannot be believed.
She also notices walked has the inflection -ed (past tense) and books has -s (plural).
Think: How does each morpheme change the meaning?
2. Understand: Meaning in small pieces
Idea 1: Morphemes
A morpheme is the smallest part with meaning. Cat is one morpheme; cats has two.
Idea 2: Bases and affixes
The base carries the core meaning. An affix (prefix or suffix) adds to it.
Idea 3: Inflections
An inflection such as -ed, -s or -ing changes tense or number but not the word’s core meaning.
3. Worked examples
Example 1 (I show you): Base
What is the base of unbelievably?
- Core.
Answer: believe
Example 2 (We do it together): Prefix
What does un- mean?
- Not.
Answer: not
Example 3 (You try): Inflection
What does -ed show?
Show the steps and answer
- Tense.
Answer: past tense
Did you know?
English has thousands of words built from a few hundred common morphemes.
Why this matters
Morphology helps you read, spell and understand new words.
4. Explore: Morpheme maker
Build words.
- Pick a base like play.
- Add prefixes and suffixes.
- Note changes in meaning.
- Write them in sentences.
Think about it: what did you notice?
You can use morphology.
5. Practise

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.
