BLED complementary asset to book. It allows to prove that the achievements of the lesson actually are implemented. I bought the book (one is the complement of the other) to deepen the lessons learned in class and I do not regret it at all because, grammar rule, spelling or conjugation learned by heart, does not always give the same result on exercise. The exercises ask the child to concentrate in the scenario and not to recite "stupidly" a learned rule. I highly recommend this method because it is one of the keys to success in French and will not hesitate to order the following years.
