      Subordination with 'when' and 'if'

      Lesson details

      Learning outcome

      I can stretch a simple sentence with 'when' and 'if' subordination.

      Key learning points

      1. 'When' and 'if' are types of joining word.
      2. A simple sentence can be stretched with 'when' to give a time frame to the first idea.
      3. A simple sentence can be stretched with 'if' to give conditions to the first idea.
      4. Joining the first idea with 'when' or 'if' forms a second idea that is subordinate to the first.
      5. Using 'when' or 'if' to stretch a simple sentence forms an adverbial complex sentence.

      Keywords

      • Joining word - a word that joins words or ideas

      • Time frame - when something happens

      • Conditions - circumstances or factors

      • Stretch - to make longer or fuller

      • Complex sentence - a sentence formed of a simple sentence joined with subordination

      Common misconception

      Pupils may think that an idea starting with 'when' or 'if' makes complete sense on its own.

      Make sure 'when' and 'if' are always presented as part of the second idea so that pupils can hear the idea does not make complete sense.

      Teacher tip

      Make the tasks more practical by providing some slips of paper with simple sentences and other slips with subordinate clauses beginning with 'if' and 'when'. This will give pupils the opportunity to play around with sentences before writing them.
