What is a sentence?
A sentence is a grammatical unit made up of one or more words (Go! is a sentence, as is The cat sat on the mat.). Sentences begin with a capital letter and end with a full stop, a question mark or an exclamation point.
What is a simple sentence?
Sentences can be structured in different ways.
A simple sentence has a subject and ONLY ONE verb:
What is a compound sentence?
Zoe can be rude at times but she is a nice girl.
What is a complex or multi-clause sentence?
Complex sentences can also be referred to as multi-clause sentences.
The connectives in complex sentences are subordinating conjunctions and they tell us about the order or the place in which things happened or specify a cause or effect relationship between events. Connectives used in complex sentences include after, although, as, because, if, since, unless, when.

The big dog barked whenever I knocked on the door.
Complex sentences can also be constructed by including relative clauses (which are subordinate clauses), for example: Tom, who liked to read, settled down happily with his new book.
How are children taught sentence construction in KS1?
Children are not necessarily taught the concept of compound and complex sentences explicitly in KS1, but teachers will encourage children to notice the use of connectives in texts they are reading and how they make the writing more effective.
In Year 1, children need to start joining parts of sentences (clauses) using 'and'. For example:
In Year 2, children need to start using subordination, which occurs in a complex sentence. So instead of writing: 'I wanted some ice-cream,' they need to expand this using the connectives 'and,' 'or' and 'but,' to something like: 'I wanted some ice-cream but there was none.'
How is sentence construction taught in KS2?
Children continue to be expected to use compound and complex sentences. They will be expected to use more and more varied and sophisticated connectives.
In Years 3 and 4 they are expected to use 'when,' 'if,' 'because' and 'although'.
In Years 5 and 6 they are expected to use 'meanwhile,' 'therefore,' 'however,' 'consequently,' and other connectives.
By Year 6 children are expected to recognise, understand and be able to explain what simple, compound and complex sentences are, as this is likely to come up in the KS2 Grammar, Punctuation and Spelling test.
Teachers use a variety of methods for encouraging children to improve their sentence structure:
- Teachers often put lists of connectives up around the classroom to encourage children to remember to use them in their writing.
- They may also play classroom games, saying sentences out loud using connectives. An example of this is to give children the half-sentence: 'I would like to get a dog, however,' and then ask them to repeat it, adding their own half of the sentence, for example: 'I would like to get a dog, however my mum won't let me.'
- Teachers will also model the use of compound and complex sentences on the board when they are drafting example text for the children.
- When a teacher marks a draft piece of writing, they may, in their marking, draw the child's attention to how two simple sentences could be joined by a connective, or how one simple sentence could be expanded by a connective and a second clause.
