Words to know
a word that can stand alone
a word part that carries the main meaning
a root meaning carry
a root meaning do
1. Discover: Carrying and doing
At the market, Kofi helped his aunt transport the yams. She said, These baskets are portable, so we can carry them easily. Later, Ama said, Our school play has lots of action, and the actor was great!
Think: Which words share the root port? Which share act?
2. Understand: Roots and base words
Idea 1: Base words
A base word can stand alone. In helpful, the base word is help. In unkind, it is kind.
Idea 2: Roots
A root carries the main meaning but may not stand alone. Port means carry: transport, portable, import, export.
Idea 3: Root act
Act means do: action, actor, react. Knowing a root helps you guess new words.
3. Worked examples
Example 1 (I show you): Base word
What is the base word in helpful?
- Remove ful.
Answer: help
Example 2 (We do it together): Root port
What does portable mean?
- port means carry.
Answer: able to be carried
Example 3 (You try): Root act
What does actor connect to?
Show the steps and answer

Answer: a person who acts or does a role

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.
