German school syllabus 1925

In the summer of 1926, Charles A Noble visited Gymnasium mathematics classes in Göttingen, Berlin, Dresden, Stuttgart, and Hamburg. He observed classes being taught according to the official guide for the Prussian Secondary School syllabus which had been issued in April 1925. Here is the Mathematics part of that syllabus for pupils between the ages of 12 and 18.
