My 4 year old daughter does not leave his slate book and trains seriously. This is great. It begins with the simplest letters to trace. There are, in addition, three examples with the concerned letter in a different color for the track well with an illustration. Sometimes examples are somewhat poorly chosen, for example "egg" for the letter O. But it will explain. The pen works well, but not for long. Fortunately you can buy them separately. Most of this book: the child can really train alone (with some minor exceptions).
