Student lesson

The lesson in 60 seconds

  1. Look for endings and beginnings you know.
  2. Divide into syllables.
  3. Read each part and blend.
  4. Check that it makes sense.

Words to know

decode
work out a word by its sounds and parts
prefix
a word part added to the start
ending
a part added to the end
blend
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?

Remember: To decode a long word, find known parts, divide it into syllables, read each part, blend them and check it makes sense.

3. Worked examples

Example 1 (I show you): Parts

Find the parts of replaying.

  1. Look for prefix and ending.

Answer: re-play-ing

Example 2 (We do it together): Read

Read: un-hap-py.

  1. 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
  1. 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.

  1. Cover the word.
  2. Find known parts.
  3. Read each part.
  4. 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 ___.

Mastery and remediation

Objective Bronze (Developing) Silver (Proficient) Gold (Advanced)
O1 Break a long word into 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
O2 Use syllables and endings to decode 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 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
O4 Check that the word makes sense 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: Guessing from the first letter. Read every part.
  2. Explain another way: use real objects, pictures or actions first, then words.
  3. Show a simpler example: Use word-part cards.
  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 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.
