Common Core Standards: Math
Before geometry turns into a mess of proofs and postulates, let's take a moment to appreciate its true, visual beauty. (Not many people can recognize the elegance of drawing a perfect equilateral triangle, but we're betting you can, teach.)
So instead of filling students' heads with theorems and conjectures, these standards are all about experimenting with geometry in as visual a way as possible. So tell your students to sharpen those pencils; it's sketchin' time.
