Sign in to track this

What mastery looks like

  • Read exception words from the Y3-4 statutory word list accurately (e.g. 'business', 'caught', 'knowledge', 'different')
  • Identify unusual letter-sound correspondences in exception words and explain why the word does not follow common GPC rules
  • Use growing knowledge of morphology and etymology to attempt unfamiliar exception words (e.g. recognise the root 'know' in 'knowledge')

Check your understanding

Can Decoding unfamiliar words read trickier exception words — like 'ordinary', 'promise', 'recent', or 'island' — without being thrown off by the parts that don't follow the usual spelling rules?
