So are you saying then that the actual math content is *assumed* to be covered by the teacher, and that the blog focuses on other issues?
Bob Hansen continually points out that the blog has no math content, and he appears generally (or at least often) to be correct. But perhaps that not really what the dy/dan blog is for. Is it all a misunderstanding?
