Rouvrou,
You mentioned traditional tales which led me to wonder if you have received the Alice in Wonderland book from Langues pour Tous, recommended by the minister of education? It comes with 1/2 the story (!), plus exercises and a CD to go with it. Looks good. I'm going to start with it this term.
Our school didn't receive it but another local one did and they don't teach Eng there so someone kindly passed it on to me. Published by

I'm going to ask the inspecteur this week about it (and if there are more freely available) when he inspects me this week (!) I'll let you know his answer.
