This program looks interesting. http://www.dynamicgeometry.com/

Has anyone used it?

Feel free to add any other geometry resources you've used or heard about in this thread!

Zome tools are a really fun way to work on geometry skills. It gets the kids thinking about planes, symmetry, angles, etc.

I"ve looked at Zome several times and could never decide what to get. What do you recommend starting with?

We have the Advanced Math set. I wanted that one so we could build all the Platonic solids. It's great! The kids are really creative with it

DS builds hypercubes and geometric patterns, DD builds skyscrapers for her toy critters.

Together, we built a dome large enough for a child to crouch under. I like playing with it, too.

I saw a video using 3D shapes to make 2D shadow-shapes. Is that part of a specific kit w/ instructions or do you just do it on your own?

Zome is a bit addictive.... LOL I think we've got the Advanced Math set (or something near it -- I pieced it together over time), and the Zome Geometry book. We've not set out to do a solid course with it yet, but we're going to have Friday Zome days next year with three other kids... probably getting through about half the book.

Yes, we have the Zome Geometry book. It is really a college level text but accessible on many levels. I have used it to create math lab activities for third graders in a heterogeneous class.

Yeah -- The group is four "really really smart", extremely math-oriented internally motivated high-achievers. It should be a wild ride... LOL

YES!

Oh you know what else is good? Euclid! The original guy I mean! We've only dabbled with it, but it's actually a fairly accessible text for messing around with things and doing compass-and-straightedge constructions. I have a companion book by Benno Artmann that makes it even more straightforward (and mentions a lot of what has been done since the ancient Greeks... LOL). That one is called Euclid: The Creation of Mathematics.
