Really a book for the under 8 crowd, although it would be worth trying for the reluctant, less competent older reader. Like the A and B books, this is wonderful as a read aloud and as a book for the child to read on his/her own. Only 120 words (a lot of repetition), 88.3% of which starts with "c." Unfortunately, no more that I know in the series (Make up your own dastardly dragons doing diabolical deeds).
This is a Dr Seuss Bight and Early beginner book. he Book begins with C is a clown and goes onto longer sentences gradually that have all C's in them. This is a beautiful gift book and learning resource.
