The recently-published Secondary Mathematics for Mathematicians and Educators offers a high-level view of the secondary curriculum suitable not only for preservice teachers at the end of their undergraduate studies but also for Mathematics and Math Ed graduate students with an interest in the connections between topics in advanced-level mathematics and the content of the secondary curriculum.  Michael will discuss the Geometry content of the book and how it connects not only to the secondary Geometry course but also to other topics within secondary mathematics.
