The Make: Math Teacher's Supplement is a guide for teachers, parents and others who are exploring teaching with the authors' Make: Geometry, Make: Trigonometry, or Make: Calculus books. It covers the philosophy behind the books as well as practical tips for managing student 3D printed workflow, classroom technology needed, assessing student understanding, and similar topics. The authors include a list of learning objectives by chapter for all three books, and a matrix of topics covered to simplify adding these materials to existing lesson plans.This guide draws on the the authors' experience training teachers to use 3D printers and OpenSCAD (the math modeling software used in the other books) to summarize what a teacher needs to know before class starts, and tips on learning enough to stay ahead of the students as they explore the 3D printable and other models in the book series. Note that this supplement presumes that the reader has one or more of the author's Make: mathematics books. It is not a "Teacher's Edition" which repeats the content of the regular edition books. Those must be purchased separately.
