Put Your Knowledge into Practice
One way of practising nouns is to chose a book at random from your bookshelf. Open it at any page and them challenge yourself to find as many nouns as possible. Remember a noun is a the name of a person, place, object or idea.
Then, if you're in need of a super challenge, why don't you sort your nouns into common nouns (the names of everyday things) and proper nouns (individual names given to people, places and things that need a capital letter).
