I bought this book to learn a little more about the Montessori method, to find activities to do with my children and especially for round detachable letters writing. I was very disappointed by discovering the contents of this book ... Very colorful, with many photos of children, but it stops there! The description of activities is poor (very very "blah") As for detachable letters, we must detach them from the book (in the arranchant ??), make enlarged copies and make them yourself ... not great!
