English · Spelling & Word Study · procedural

Distinguish and correctly spell homophones and commonly confused words at Y5-6 level (e.g., affect/effect, practice/practise, advice/advise, complement/compliment, aisle/isle, led/lead), including confused words such as to/too/two and there/their/they're

What mastery looks like

  • Select the correct spelling from a pair of homophones by analysing meaning in context, e.g. 'The doctor's advice (noun) was to practise (verb) daily'
  • Spell commonly confused words accurately by applying word-class clues: advise/advice, practise/practice, licence/license (verb ends in -ise, noun ends in -ice)
  • Identify and correct homophone errors in extended writing, including to/too/two, there/their/they're, whose/who's, and its/it's

Check your understanding

When Homophones (age 9+) writes, do they use the right spelling for commonly mixed-up words — like "affect" vs "effect," "practice" vs "practise," or "there," "their," and "they're"?
