I gave my 10 year old daughter. It is both educational and fun, the evidence is that adult myself leafing I allowed myself to read and learn. I highly recommend it!
This little book is very nice. It will give a good basis for children CM1 and even learn the small things to others. This is not a textbook, it is much more fun.
My son was not thrilled CM1 a priori and as soon as he started has eaten ... The text is very well chosen for a child this age and very well done illustrations; I also learned or relearned many things ...
This book is very well done. He answers in a clear and pleasant to most questions that a child 8 to 12 years might arise in the Middle Ages. This book is well illustrated.
