Make Your Own Math Printouts (Dynamic Paper, NCTM)

This is so cool!

If you visit NCTM's Illuminations, you'll find Dynamic Paper. Description from the site:

Need a pentagonal pyramid that's six inches tall? Or a number line that goes from ‑18 to 32 by 5's? Or a set of pattern blocks where all shapes have one-inch sides? You can create all those things and more with the Dynamic Paper tool. Place the images you want, then export it as a PDF activity sheet for your students or as a JPEG image for use in other applications or on the web.

 Basically, you can make a myriad of handouts: nets, graph paper, number lines, number grids, tessellations, shapes, and spinners. All your invention, by using their tools. Very, very cool. Check it out!
