I discovered this series of coloring by chance in a bookstore holiday. As soon as I took my class the following year, I bought the set for my students, dragons, knights, kings and queens, princesses, prehistory, Gallo-Roman ... etc. They punctuate my lessons about this or that aspect of the story, or stories recounted in the classroom and give students a different graphic universe than cartoons are usually found on the net or in trade. In short, it's a bit serious coloring, but that appeals to 7-10 years ...
