You could use this book when you've been teaching pets in French and want to look at extra fun animals; it is great to look at pronouns and their positions in French sentences; it also helps to make children aware of certain sounds, like "-euil", and rhymes. Finally, it is a lovely story about team work!! All in all, a great book!!
If you would like to borrow it, I can lend you all the puppets you need to re-enact the story with your pupils. Success guaranteed!
