We have just completed mid-year of the PS 2 notebooks Owl (very good: math & logic French design: I have not bought "reading" this year): the exercises are well designed, comfortable and neither too easy nor too difficult mid-year, fun and colorful. Rather quick in addition, they do not necessarily require a long concentration. For the rest, I acquired a new notebook that seems BOSCHER exellet: exercises are exactly what they are doing in school, highly scalable and complete.
