Here little games and original exercises that have delighted my daughter. Unfortunately, there are only five different types of exercises that are repeated throughout the book. Once she understood the trick, my daughter finished the book in 2 days: not terrible for review. Some exercises are to break the monotony but they are not the CP level and totally infeasible for a child of 6-7 years. The famous puzzle with a "Grand design" is at the limit of the scam. Given the book format (A5), the term 'large' is a little presumptuous and as for the rest of the book, once you actually one, the other 5 are trivial.
