Student lesson

The lesson in 60 seconds

  1. The letter r changes the vowel sound.
  2. ar says /ar/ as in car.
  3. or says /or/ as in corn.
  4. er, ir and ur all say /er/.

Words to know

r-controlled
a vowel changed by the r after it
ar
the pattern in car
or
the pattern in corn
er
the pattern in fern, bird and turn

1. Discover: The bird at the farm

Tolu goes to the farm on a hot morning. He sees a barn, a horse and a bird. The bird sits on a fork in the corn. “You are early,” says the farmer. Tolu turns to go and the girl in the red shirt waves.

Think: Which words have ar, or, er, ir or ur?

2. Understand: R-controlled vowels

Idea 1: What changes?

When a vowel is followed by r, the vowel sound changes. It is not long or short. It is r-controlled.

Idea 2: ar and or

ar says ar as in car, farm, barn. or says or as in corn, fork, horse.

Idea 3: er, ir, ur

er, ir and ur all say the same sound: fern, bird, turn. You must remember the spelling.

Remember: R-controlled vowels: ar says ar, or says or, and er, ir and ur say the same sound.

3. Worked examples

Example 1 (I show you): Read

Read: farm.

  1. ar says ar.

Answer: farm

Example 2 (We do it together): Spell

Spell the word for a bird that says tweet, with ir.

  1. b-ir-d

Answer: bird

Example 3 (You try): Same sound

Which pair sounds the same: fern, turn or farm, fork?

Show the steps and answer
  1. er and ur sound the same.

Answer: fern, turn

Did you know?

Er, ir and ur sound the same, so spelling needs memory and many examples.

Why this matters

R-controlled vowels are common in English words. Learning them helps with reading and spelling.

4. Explore: R-controlled sort

Sort words by pattern.

  1. Read the word cards.
  2. Sort into ar, or, er/ir/ur.
  3. Read each pile.
  4. Add a new word.
Think about it: what did you notice?

You can sort r-controlled words.

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: Reading car as cat. Look for ar.
  2. Explain another way: use real objects, pictures or actions first, then words.
  3. Show a simpler example: Use picture 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 r-controlled vowels. You do not need to be an expert to help.

  • Read r-controlled words.
  • Play word hunt.
  • Praise careful reading.
  • 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.
