This Real Grammar resources pack provides everything that you need to successfully explore adding the prefix un- to words with your pupils in Year 1 or to revisit this learning.

What is a prefix?

A prefix is a group of letters that can be added to the beginning of a word to a create a new word. There a variety of prefixes that can be added to words and in Year 1, the prefix un- is introduced.

What happens when we add the prefix -un to words?

The prefix un- means ‘not’ or ‘the opposite of’ and so helps create words with opposite meanings.

  • happy – unhappy
  • well – unwell
  • tidy – untidy

What is included in this resource pack?

This pack is divided into five parts:


    This section includes PowerPoint teaching slides and teaching notes with an optional script to introduce adding the prefix -un to words. It can also be used to revisit this aspect of grammar with pupils.


    An independent activity for pupils to practise using what they have been taught, allowing teachers to assess understanding.


    A series of short, 10-minute activities that can be used following the TEACH session to revisit and rehearse what has been taught. These may be short writing tasks, grammar games or editing/proofreading activities.


    A short writing task where pupils can use the grammar skills taught in context to produce independent writing.


    Three SATs style test questions, including cloze activities and multiple choice quiz questions, based on the grammar that has been taught.

  • Teachers can choose which section of the resource pack to use according to their pupils’ needs and could use the activities over a series of lessons or weeks

    Teacher notes are provided to show how these quality resources could be used with pupils.

    How is this resource pack differentiated?

    The PRACTISE and REVISE sections include three activities differentiated for three levels of ability:

    • Worksheet 1 for pupils who may need support. Questions will have a lower cognitive domain (what is being asked of pupils) and/or vocabulary used may be simplified where possible.
    • Worksheet 2 for pupils working at age related expectations.
    • Worksheet 3 for pupils who may need an additional challenge and may be working at a greater depth in this area. Questions will have a higher cognitive domain with more challenging vocabulary.

    SUPPORT and CHALLENGE ideas are also included in the teacher notes of each section where relevant, with ideas of how to support pupils working towards the expected standard or at greater depth in this area.
