Vocabulary, Grammar and Punctuation
Grammar is naturally learnt through spoken interactions and reading. Explicit knowledge of grammar is very important as it gives us greater control and effect in both spoken and written forms. For example, being able to present a persuasive speech for/against a new housing development.
Building this knowledge is best achieved through direct teaching within reading, writing and speaking. Once familiar with grammatical concepts children are then ready to explore the concept in their own speech and writing, recognising its effect.
