Why this why now

This unit uses and builds on pupils' knowledge of explanation text writing from the Year 3 unit 'Mummification: explanation text'. Pupils write using an introduction, themed sections and conclusion paragraphing structure, applying a range of formal and viewpoint fronted adverbials and a range of causal conjunctions to their writing. Year 4 level sentence structures are also reviewed and applied. This unit prepares pupils for more non-fiction writing in the non-chronological report style in the Year 4 unit, 'Ancient Greeks or Anglo-Saxons: non-chronological report'.

Prior knowledge requirements

  • Nouns and pronouns can be referred to in a range of ways to avoid repetition.
