Children are taught the meanings of different prefixes (for example: 'bi' means 'two'). Then they will look at words with these prefixes and how that meaning is incorporated into the word, for example: a bicycle has two wheels and a bilingual person is fluent in two languages. This 'breaking down' of words helps children to understand the meaning of other words and to think carefully about how these words are spelt.
