This book is great, even for adults! I personally bought this book for myself, take a break! I did not like the book so much art therapy where you have to color ... I'm still disappointed with the result. So I opted for a guided coloring where color is indicated >> I am not disappointed for colors and it's great to discover As the image mystery! This little book is composed of 3 different activities (several times in the book): "colos pixels" (color the color space specified by the tiny square), "the naval battles pixels" (color the squares with coordinates written) and "pixels drawings" (drawing by following the code and the compass). All solutions are at the end of the book. Games written very well for adults, and I think my students would enjoy CM too! Try it !!!
