What are prepositions?
Prepositions are linking words in a sentence. We use prepositions to explain where things are in time or space. Prepositions tell us where something is (for example, beside, under, on, against, beneath or over) or when something is happening (for example: until, during, after, before or more specifically 'on Christmas Day', 'at twelve o'clock' or 'in August').
Prepositions usually sit before nouns (or pronouns) to shows the noun's (or pronoun's) relationship to another word in the sentence.
When and how are children taught about prepositions?
In the Foundation Stage, children may be asked to describe the position of an object, using words such as next to, under, in, on, opposite, beside, etc. This will help them expand their vocabulary which will in turn improve their speaking and writing.
In KS1 and KS2 children use a greater variety of prepositions. In particular, when children use prepositions to tell us when something is happening, they are also referred to as time connectives.
Children will be encouraged to use time connectives in lots of different kinds of writing in Years 1-6. Time connectives are often used in fiction, but are also used in non-fiction genres such as recounts, biographies, instruction texts and information texts. Teachers will often have a list of time connectives on display in the classroom for children to refer to when they're writing.
The instruction text below includes time connectives (or prepositions) in bold:
First, boil some water in a saucepan on the stove.
Next, stir the water.
While the water is swirling, crack your egg and drop it in the water.
Leave the egg in the water for two minutes.
Finally, remove the egg from the water with a spoon.
There are around 150 prepositions in English, but we use them more frequently than other individual words. The prepositions of, to and in are among the ten most frequent words in English. Common prepositions include these words:
