TITLE: Resource for learning straightedge and compass constructions
QUESTION [5 upvotes]: Does anyone know a good resource for learning about straightedge and compass constructions besides "The Elements?" I tutor geometry to middle-schoolers and high-schoolers and thought that including construction problems might give them better intuition for the subject. I know most of the constructions in book 1 of The Elements, but would appreciate it if anyone could point me in the direction of a book or other resource that has interesting construction problems, hopefully graded by difficulty.

REPLY [5 votes]: For compass and straightedge construction (personally, I still learn best by manually doing what I'm learning), see, e.g.,:

Geometric Constructions  (mathopenref.com) gives a brief history and provides references and links to dozens of geometric constructions, each with detailed instructions.
Compass-and-Straightedge (a site created by David Eppstein with dozens of links to specific constructions.)


The following isn't a recommendation regarding pencil and paper geometric constructions, or resources that involve literal use of compass and ruler, but I've found that software like geogebra is extremely helpful when learning and/or teaching geometry, and is useful and appealing to pre-teens, all the way up to post-secondary students (and their teachers and tutors!) 
Given that today's children and teens typically have developed facility with and attraction to computer applications, it is appealing to even the most resistant students!
The software helps students readily construct and manipulate geometric objects, as well as better understand, through immediate visualization, how changes in certain parameters affect resulting geometric constructions.
You'll find many applications, teaching lessons, tips, and such at geogebra.org (linked above, where you can download the software, and find links to curriculum, downloads, teaching tips, and discussion boards, etc.).
Note: Geogebra is free and well-supported software available for download to anyone and everyone.
One additional helpful package, very user friendly, (there's a minimal expense, but a lot of support) is the Geometer's SketchPad (see resources available at Dynamic Geometry).
