Student lesson
- Look for endings and beginnings you know.
- Divide into syllables.
- Read each part and blend.
- Check that it makes sense.
Words to know
work out a word by its sounds and parts
a word part added to the start
a part added to the end
put the parts together
1. Discover: The unhappy elephant
Kofi reads a book about an elephant. He sees the long word unhappy. He covers un, reads hap-py, then puts them together: un-hap-py. “The unhappy elephant!” he reads. Then he sees playing. “Play and ing,” he says. “The elephant was playing!”
Think: What steps did Kofi use?
2. Understand: Decoding strategy
Idea 1: Look for parts
Look for parts you know: a prefix like un-, an ending like -ing or -ed, and vowel patterns.
Idea 2: Divide and read
Divide the word into syllables: un-hap-py. Read each part.
Idea 3: Blend and check
Blend the parts into a word. Ask: does it sound like a real word? Does it make sense in the sentence?
3. Worked examples
Example 1 (I show you): Parts
Find the parts of replaying.
- Look for prefix and ending.
Answer: re-play-ing
Example 2 (We do it together): Read
Read: un-hap-py.
- Blend the parts.
Answer: unhappy
Example 3 (You try): Check
The word is unhappy. Does it fit: The elephant was ___?
Show the steps and answer
- Does it make sense?
Answer: yes
Did you know?
Good readers decode long words in less than a second because they spot the parts.
Why this matters
Decoding helps you read new words on your own.
4. Explore: Decode it
Decode long words.
- Cover the word.
- Find known parts.
- Read each part.
- Blend and check.
Think about it: what did you notice?
You can decode longer words.
5. Practise
Say it in a sentence
Use these starters when you talk about the lesson. Say them out loud.
- I look for the prefix ___.
- I look for the ending ___.
- I divide it into ___.
- I check that it makes ___.

Exam practice
These questions are written in the style of common school and international primary assessments. Try them on your own, without looking back. Then check your answers in the marking guide. The marks are shown in brackets.
- What does decode mean? [1 mark]
- Name a prefix and an ending. [2 marks]
- Divide unhappy. [1 mark]
- Why check the word makes sense? [1 mark]
- Explain how to decode a long word. [3 marks]
Total: 8 marks.
Marking guide and model answers
- work out a word [1]
- a prefix [1]; an ending [1]
- un-hap-py [1]
- to be sure it is right [1]
- find known parts [1]; read and blend them [1]; check it makes sense [1]
Score guide: 7 to 8 = secure. 5 to 6 = nearly there, revise the parts you missed. Under 5 = work through the lesson again with a grown-up.

| O3 Blend the parts into a word | 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: Guessing from the first letter. Read every part.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Use word-part cards.
- 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 learns to read longer words in parts. You do not need to be an expert to help.
- Cover and reveal parts.
- Read long words together.
- Praise good decoding.
- 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.
