What mastery looks like

  • Identify and correct unnecessary tense shifts in a given paragraph
  • Edit own writing to ensure consistent tense use throughout a narrative
  • Explain when a tense shift is appropriate such as when describing a flashback

Check your understanding

If you read back a paragraph Consistent verb tense has written and it unexpectedly switches from past tense to present tense mid-way through, can they spot the shift and correct it so the tense stays consistent?
