Grammar and Creativity

I don't see any conflict between grammar and creative writing. So I hope my series of English books for 7-11 year olds will stretch imaginations as well as teach basic rules.  Of course, the rules are never fixed - which might sound like a contradiction in terms - but like any other aspect of culture, they change slowly over time.  It doesn't mean they're not worth learning.  To brighten up the whole learning process, I have sprinkled the text with illustrations.  To the right, you'll find some of those I'm doing for the Year 4 book.
