Real Grammar
  • Covers every objective for years 1-6
  • Five-step sequence ensures deep understanding
  • Includes asssessment and revision tools

This Real Grammar KS2 resources pack provides everything that you need to successfully explore how causal conjunctions can be used to introduce a cause, reason or explanation within sentences with pupils in Year 3 or to revisit this learning. Teaching slides, worksheets, games and an opportunity to apply the new learning in a writing task are all included to create a complete resource to teach pupils when these conjunctions can be used. This builds on pupils’ knowledge of conjunctions in KS2.

Year 3 Real Grammar packs are available on the use of subordinating conjunctions, co-ordinating conjunctions, both co-ordinating and subordinating conjunctions and subordinate clauses. Pupils will need to be familiar with main clauses before completing activities in this resource pack.

The model text explains the functions of parts of a flowering part. The writing task gives pupils an opportunity to explain their understanding in another area of science or could be adapted to suit your current topic.

What is a causal conjunction?

Causal conjunctions are words and phrases used to introduce a cause, reason or explanation for a given action within a sentence. They are used to explain and are found in explanatory texts as well as other types of writing. Examples of causal conjunctions include:

  • so
  • because
  • as
  • yet
  • now that
  • due to
  • since
  • so that
  • though
  • as a result

  • There was a traffic jam so we were late.
  • I forgot my jacket as I was running late.
  • I got soaked in the rain because I forgot my jacket.
  • They worked hard to learn their spellings so that they knew them for the test.

The causal conjunctions can also be placed at the beginning of the sentence.

  • Because I forgot my jacket, I got soaked in the rain.
  • As I was running late, I forgot my jacket.

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 causal conjunctions. 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.


Five 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 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.
