Learning journey

Your child is learning important grammar skills — understanding how to build more complex sentences, use punctuation correctly, and choose the right words to make their writing clearer and more interesting.

Evidence of understanding

  • Write 'I stayed inside because it was raining' using a subordinating conjunction
  • Use 'but' and 'or' to join ideas: 'I wanted to play but it was raining'
  • Use 'when' and 'if' clauses in writing: 'If it stops raining, we can go outside'

Assessment prompt

When Subordinate clauses writes a story or a message, can they join two ideas with words like "because", "but", "when", or "if" — rather than writing every thought as a short separate sentence?
