Topics in Mathematics for the 11th Grade
The series Mathematics for the High School has been specifically designed with math teachers in mind. Not only are the books a useful resource for gaining familiarity with teaching approaches used in a Waldorf school, but they are also a source of inspiration - offering a fresh perspective and new insights - for courses that may have already been taught many times.
