Sign in to track this

What mastery looks like

  • Read words with r-controlled vowels (e.g. 'car', 'bird', 'fork', 'her')
  • Recognise that 'r' changes the vowel sound (e.g. 'cat' vs 'cart')
  • Spell words with common r-controlled patterns

Check your understanding

When R-Controlled Vowel Sounds reads words like 'car', 'bird', 'nurse', or 'fork', can they recognise that the 'r' after the vowel changes its sound, and read the word correctly?
