What is an explanation text? 

An explanation text is a piece of writing whose general purpose is to inform its reader of how something works, and perhaps even how the reader might carry out a process (in the case of a more simplistic form of explanation text: instructions). Whereas a simple information text might tell the reader about the existence of something, an explanation text (otherwise known as explanatory texts) explains how or why that thing came to be in existence. 

Children will encounter many non-fiction texts that incorporate explanations, particularly in curriculum subjects such as geography and science.

As readers they will gain understanding of the ‘how and why’ relating to the subject content, but as they learn to write their own, children become the ones who pass on this knowledge. 

Although the writing of explanation texts takes some careful and specific teaching, explanations are a part of children’s every day oral, aural and mental experience: children hear explanations at home and at school, and they explain things to each other and to adults just as much as they have things explained to them.

Even the way we think about how to do everyday tasks is a kind of self-explanation. When it comes to writing explanation texts, pupils therefore have a strong starting point that should be explicitly pointed out to them and capitalised upon in the way that they are taught to transcribe such explanations. 

What should children write about? 

This is a very important question to ask, and one that cannot be answered with a blanket statement. In fact, it can only be answered by each individual teacher using the knowledge they have of the children in their class.  

Essentially, pupils can either choose something they know a lot about; or something that is made up. If you decide that children should write about something they know a lot about, there are further decisions for you to make.

Children could write about something which is within their own personal area of expertise, or they could write about something that they have learned at school.  

The first option (writing about something of which they have personal experience) would potentially lead to 30 pieces of unique writing per class – which has the potential to be more factually correct as each piece will be about something that each child knows lots about.

Taking this approach can mean that children are less focused on the content, and more focused on the writing skills you have taught them.

However, with regards to content, it can be more difficult for teachers to provide feedback on. As many schools favour a cross-curricular approach to English, this may not be an option available to you, but it is worthwhile considering as a precursor to a piece of writing that is linked to other subjects in the curriculum. 

The second option (writing about something they’ve learned at school) might be more manageable for you as a teacher, but there is the very real problem of children not understanding the content well enough to be able to write about it with sufficient accuracy.

Usually, it will take a number of weeks for children to become secure in the knowledge of a process such as the water cycle, meaning that they would only have the best chance of writing about it with confidence after the learning has taken place.

However, it can often be the case that teachers and children are working towards the piece of writing at the same time as learning the content, which leads to confusion.

Taking this approach can mean that children focus more on the accuracy of the subject content (in this case geography and science) rather than the writing skills they are working on.

Writing about made-up creatures enables pupils to concentrate on their writing, rather than the facts

The third option is for children to write about something that is made up – to write a piece of fictional non-fiction.

Aiming towards this as an outcome means that children can write within the genre without worrying about whether the facts are right or not.

It also allows teachers to focus their assessment solely on the writing skills without getting bogged down in whether or not children are demonstrating accurate science or geography knowledge, for example.

This is where teachers can be really creative, linking the subject of the explanations to machines found in picture books and short films, made-up creatures and any manner of other things. 

Depending on how long is given over to your explanation text teaching sequence, you might be able to progress through each option, probably starting with made-up content, moving to a child’s own interests, before finishing with a piece linked to another curriculum area. 

How to write an explanation text 

Explanation text example - water cycle

When thinking about how you will go about teaching a particular kind of writing, it’s always helpful to deconstruct an example text. Look at the example entitled ‘The Water Cycle’ – let’s think about what we can learn about what teachers should teach and what children should write from this text: 

Features of an explanation text KS2

Firstly, look at the main features of the text, which should form the bulk of what is taught and practiced throughout the unit: 

Paragraphs used to group related ideas 

The National Curriculum requires that children in Year 3 are introduced to paragraphs as a way to group related material. 

The example has very short paragraphs, making it easier for the younger reader to understand. This is similar to most non-fiction books aimed at children, so any examples you share from real texts will almost certainly have similarly short paragraphs.

It’s worth remembering that when children hand-write paragraphs of similar length, it will look like a lot more than the word-processed example! 

Short paragraphs demonstrate how related ideas can be grouped

The short paragraphs also demonstrate how specifically related ideas can be grouped. Look at the first paragraph of the Water Cycle text under the subheading What do we mean by ‘changing state’?

It is four sentences long, and the sentences themselves are not long either. The paragraph is very clearly about the three states that water can exist in. The following paragraph is limited to focusing on the idea that water can change between the states.  

Both ideas could exist within one paragraph, but grouping information like this is one way of demonstrating the understanding that readers are likely to comprehend what they are reading better if information is clearly presented and not too complicated. 

Children often default to disregarding paragraphing altogether, so teaching this skill is important and is transferable to most other forms of writing.

A unit of work on writing explanation texts is the perfect time to really labour on this objective as it is perhaps the text type where clarity is of the most importance: if the information is not presented clearly, the reader may not understand the content properly. 

Activities that focus on grouping information are a necessary precursor to children being able to write in paragraphs.

Simply giving the class a set of statements and asking pupils to group them is a good way to begin to do this. You could start with very obviously unrelated statements, such as facts about three different animals which need to be sorted according to the animal.

You could then move onto statements that are more subtly different in their content: facts about one animal, but some which relate to its eating habits, some about its habitat, and others about its risk of extinction, for example.

This same activity could be taken further, zeroing in on one animal’s habitat but with facts relating to country, biome and construction. 

When children are ready to organise their own content into paragraphs, you can try a similar task, this time using statements written by the pupils themselves.

Being able to physically manipulate the content is key here, and potentially avoids lots of rewriting at a later stage of the drafting process.

Using sticky notes and an A3 writing frame can work well, effectively forming a first draft once children are satisfied that they have grouped their information correctly. 

Title and subheadings to label content 

Writing a title (or heading) should be fairly straightforward – children just need to know that it should summarise what the whole piece of writing is about.

To ensure pupils are secure with this, try activities like multiple choice questions, where children select the best heading (the other options could be better suited as subheadings which sit throughout the main piece of writing); and heading writing for pre-existing explanation texts (this could perhaps be the focus of a reading lesson, once they’ve read an explanation text). 

Subheadings could be seen as optional, however it is a statutory requirement of the National Curriculum from Year 3 onwards to teach children to use headings and sub-headings to aid presentation. More importantly, it is a feature that aids in the skill of grouping information. 

You can decide on subheadings as a tool prior to grouping information, or once the information grouping has occurred as a way of defining the group that has been created.

Either way, the generation of subheadings should be a part of those practice activities so that when children come to writing a full explanation text, they have their subheadings already written. 

In the example text, there are subheadings for the three main sections of the text, and one for the summary. The introduction sits under the main heading.

This is a simple enough structure that you can teach, and ask children to follow. The example text also structures its content around three main questions.

Using questions as subheadings provides structure

Using questions as subheadings provides further structure for the content of the paragraphs. Children can focus on ensuring that their content helps to answer the question, and if it does not, they can consider revising and removing that part of their text. 

How to write an explanatory text introduction 

These are notoriously difficult for children to write, but can build on any prior work they have done about writing introductions and summaries as many non-fiction text types feature similar beginnings and endings.

Extensive modelling should be employed here, with teachers exemplifying the writing of introductions and summaries multiple times during the unit.  

The basic principles of an introduction for children in KS2 are that it should appeal to the reader’s curiosity and be very clear on what the text is going to be about. You can also consider: 

  • Go-to stock phrases and sentence structures may come in handy, particularly if you are teaching this text type towards the beginning of KS2. 
  • Including questions that children might have had themselves, making sure the content connects with the natural curiosity of children: ‘Have you ever wondered…?’ 
  • Facts that the reader will likely already know, coupled with a ‘but’ and a question, to begin to extend the reader’s thinking and to pique their curiosity: ‘Rivers flow into the sea but how does the water get into the rivers?’ 
  • A statement that shows the writer hopes to explain something more to the reader. The example in the text isn’t explicit in this, but intends to put an idea into the reader’s head; the idea that reading the rest of the text would be a good idea: ‘Understanding the water cycle can give us the answer to all these questions and more.’ 

Phrases to avoid, particularly for children at the upper end of KS2, are the ones that children reach for when they feel stuck. For introductions, these include: 

‘This piece of writing is about…’ 

‘In this text you will find out about…’ 

‘Read on to find out more.’ 

Children do not need to write full explanation texts in order to practise writing introductions. After studying them in class texts, perhaps linked to their work in other subjects, children can begin to write their own three- or four-sentence introductions to texts about almost anything – they don’t need to know too much about the content of the rest of the piece of text as at the practise stage, as they aren’t actually going to write it. 

How to write an explanatory text summary 

Children in KS2 need to understand that a summary should actually explain in just a few sentences what the main learning takeaway is.

As writers, they should attempt to tell the reader what they have just learned, but in fewer words, with less of the explanation, and focusing on the main points only. 

Again, some taught phrases and structures will be useful: 

  • A sentence or two that point out why it is useful to know the content of the explanation text they have just read: ‘Knowing about… helps us to understand…’; ‘It also helps us to see that…’ 
  • A one-sentence summary, that contains the central point of the text, and which might refer back to the questions asked in the introduction: e.g. ‘The rain water that flows into our rivers will one day be rain again!’ 

Phrases to avoid in summary writing: 

  • ‘I hope you have learned more about…’ 
  • ‘This piece of writing was about…’ 
  • ‘In summary…’ 

In terms of practice activities in the lead-up to writing summaries, once children have studied existing summaries, and have seen the teacher modelling how to write one, they could focus on identifying the main points in an explanation text, and then write a summary for it.

The identification of main points alone is something that pupils often struggle with, so some shared work where they help to identify them, followed by the teacher modelling how to use them to write a summary will be necessary.

When it comes to summarising and identifying main points, and in order to ready the children for writing summaries, practise writing a 20-word summary of something they have learned or read; then challenge them to reduce their summary to 10 words, then 5, causing pupils to really think about what the key information is. 

For a summary, focus on identifying the main points in an explanation text

Technical terms 

Children should be encouraged to think through the technical vocabulary that is related to their subject, and to include this in their text.

They need to know that technical terms are usually defined within the text, or in a glossary section, to ensure that the reader understands what the words mean.

They should see that an explanation text relies on some technical vocabulary to explain concepts, but that if readers do not understand those words, they may not understand the overall explanation.  

In preparation for including technical vocabulary, children should select the words they want to use and to write or find definitions for them – later on they can work out how to weave these words and definitions into their text. 

Grammatical techniques 

You may also want to teach specific grammar features for an explanation text, as set out in the National Curriculum. These will vary depending on which year group you are teaching, and which objectives you have already taught. 

If selecting grammar-based objectives, ensure that they are suitable for the text type. For example, choosing to teach present perfect tense during this unit is not appropriate to what we’re trying to achieve with the text, whereas teaching the use of conjunctions, adverbs and prepositions to express time and cause is essential to explanation writing. 

The National Curriculum provides useful guidance as to the type of words that can be taught to aid in the writing of explanation texts.

In Year 3, it outlines that children should work on expressing time, place and cause using conjunctions (when, before, after, while, so, because), adverbs (then, next, soon, therefore), or prepositions (before, after, during, in, because of). 

Explanation texts Year 4 

If teaching explanation texts in Year 4, the use of noun phrases and fronted adverbials are both suitable teaching points that relate to the text type, as is learning around making the appropriate choice of pronoun or noun within and across sentences to aid cohesion and avoid repetition. 

Explanation texts Year 5 

In Year 5, relative clauses beginning with who, which, where, when, whose or that can work well in explanation texts, and some modal verbs may be appropriately used too. Brackets, dashes or commas to indicate parenthesis all have a place in more complicated explanation texts, too. 

Explanation texts Year 6 

Passive voice can be used effectively in Year 6 explanation texts, and most forms of punctuation taught in Year 6 can be used too. 

Explanation text examples 

This KS2 water cycle explanation text example could be adapted to include any of the above text features should you wish to use it in your year group. 

Teaching of explanation texts 

Explanation texts are a versatile and widely-adaptable text type to teach, with relatively few key features that need to be focused on in order for children to be able to write a good one. Some of the key features are transferable from or to other kinds of non-fiction writing, and in general, pupils seem to enjoy writing them.

Assessing explanation texts 

As you teach your children to write explanation texts, keep in mind what your assessment focus is – you want to hone in on the English skills rather than the accuracy of the content.

It’s easy for children to get bogged down in the details of the content, so make sure you reassure them that it’s OK if they get a fact wrong, and that you want them to focus on being able to write well.

Making the right decision in the first place about what the content of the text will be will help hugely with this.
