Precalculus-level Projective Geometry Reference I'm teaching a course right now at the pre-calculus level (an "ideas in math" class) and would like to know if anyone knows of
1) A nice source of problems
and/or
2) An accessible set of notes that the students can read.
I don't need a lot of material; we're not going much beyond the definitions (adding "points at infinity" to the plane, and a short discussion of projective coordinates). I'll write my own materials if I can't find anything I really like, but I'd rather not re-invent the wheel, and a quick Google search hasn't turned up anything useful.
 A: I think the text: 
Viewpoints: Mathematical Perspective and Fractal Geometry in Art 
by Marc Frantz, Annalisa Crannell
ISBN-13: 978-0691125923
ISBN-10: 0691125929 
might be something you're looking for.
I have worked some of the problems and read some of the text and it seems to be a hands on introduction to some of the basic concepts in projective geometry.
Get back to me if you look at it and think it works for you.
A: checked my mostly unread Dover math used book collection
Introduction to Projective Geometry, Wylie
Linear Geometry, Artzy
Projective Geometries and Projective Metrics, Busemann and Kelly
A Modern View of Geometry, Blumenthal
all have at least a chapter on Projective Geometry
Geometric Algebra is useful in Projective/Homogeneous modeling
Geometric Algebra for Computer Science, Dorst, Fontain, Mann has a chapter or two that are relevant, although the doulbly homogeneous 5-D model of 3-D Euclidean space is the main thrust
A: Projective Geometry by Coxeter (2nd edition, Springer-verlag) could be helpful for you and your students.
This small book contains a lot of exercices and their solutions (since there are solutions, it might be more suitable for you, in order to prepare your notes and your problems, than for your students).
