In the Waldorf curriculum, Trigonometry is taught in 12th grade. Harry Kretz has created a beautiful course that is a nearly perfect conclusion to a student’s Waldorf education.In his lessons, he uses all sorts of commonly available materials – making the point that expensive laboratories are not necessary for teaching basic scientific principles. The simplicity of the lessons is of the sort that leads to deep thinking and sound understanding – as well as genuine student interest in the subject.
