Teacher CM1 / CM2 for 7 years, I end up with a class of GS / CP in September ... I quickly looked for a book "Swiss Army knife" that allows to navigate to prepare this new level. I relied on positive comments on this title and I ended up ordering it: good pick! It provides a comprehensive overview of the level, the use of time via the organization of the class to the material, it also goes into areas seen one after the other built and detail always with ideas very relevant and varied activities. What is very significant is the very professional and efficient side, with the almost permanent presence of objectives and skills to be achieved, proposals for remediation and also progressions. The organization and presentation of the book was a bit surprised at first because it is dense and works with paintings, drawings and illustrations documents. But after this first surprise, within minutes I dove into it! This is not a theoretical book "pédagogise" pompously but a practical book, a real practical tool. Of course it is not everything, but it's a good base to take cues of quality and ideas, and then build her class! So glad I ordered one for GS!
