Lesson details

Key learning points

  1. 'Because' is a joining word.
  2. A simple sentence can be stretched with 'because' to give a reason to the first idea.
  3. Joining the first idea with 'because' forms a second idea that is subordinate to the first.
  4. Using 'because' to stretch a simple sentence forms an adverbial complex sentence.

Common misconception

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

Make sure that 'because' always begins the second idea so that pupils can hear that the idea does not make complete sense by itself.


  • Joining word - a word that joins words or ideas

  • Reason - explanation or justification

  • Stretch - to make longer or fuller

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

Use the term 'complex sentence' as opposed to exposing pupils to 'adverbial complex sentence' terminology at this point. For teacher subject knowledge, an adverbial complex sentence is formed of a main clause and an adverbial (because) clause.
