I study "Le Petit Prince" with some IB students ( Language B ) and so far, I have found these links to add to my lessons about the symbols in the book.
If you have some more ressources about this topic, could you please let me know?

The is a CD-ROM dedicated to Le Petit Prince: The CD-ROM gives an engaging on screen version of the text of this well-known story, complete with St Exupéry’s own illustrations.

Thank you for adding this cd-rom. I had forgotten to mention it. My students like it too but found that it was too long to "tame the fox"...
