What mastery looks like

  • Identify whether a spoken or written example uses formal or informal language (e.g., 'Dear Sir' vs 'Hey mate')
  • Rewrite an informal sentence in a more formal way (e.g., change 'Can I have some?' to 'May I please have some?')
  • Explain why formal language might be used in one situation and informal in another (e.g., a letter to the headteacher vs a note to a friend)

Check your understanding

Does Formal and Informal English understand the difference between how they'd write a text to a friend versus a formal letter — and can they explain why the language would be different?
