Homophones

English · Spelling & Word Study · procedural

Distinguish and correctly spell common homophones and near-homophones encountered at Y3-4 level (e.g., accept/except, affect/effect, brake/break, grate/great), including using the /eɪ/ sound spelt ei, eigh, or ey

Sign in to track this

What mastery looks like

  • Spell pairs of homophones correctly in context (e.g., 'there/their/they're', 'brake/break', 'grate/great')
  • Choose the correct homophone to complete a sentence (e.g., 'The dog wagged its/it's tail')
  • Spell words with the /eɪ/ sound as ei, eigh, or ey (e.g., vein, eight, they, neighbour)

Check your understanding

When Homophones writes, do they use the right spelling for words that sound the same but mean different things — like "brake" (on a bike) and "break" (snap something)?
