We use it in school until EC1. There is little geometry and measurement. Although expertise in these two areas seem less important for some people that count and "calculation", if we do not complete this from the CP, he suffers a major difficulty at the beginning of Cycle 3 (CE2 ). Otherwise I find this book (improved compared to the old edition) very interesting and very well done regarding the numbers and calcul.Merci "Purchase checked on Amazon"
