Ages 7 and up, with adult help to get started
Go buy a stack of the cheapest paper plates you can find, a pack of bobby pins, and a roll of tape, and you'll be ready for a fun bit of hands-on geometry.
Artist Bradford Hansen-Smith creates geometric art by folding paper plates and connecting them with bobby pins and tape. You can do the same by following the instructions on his site. In doing so, you'll make geometric solids your kids may only have encountered on a page in a math book - tetrahedrons, octahedrons, and others. It's easiest to follow the instructions with actual paper plates in your hands (rather than trying to imagine how the steps work). Once you make a shape yourself, it's very easy to explain it to a child. The shapes take just a minute or two to fold.
On the Gallery pages of the site you can see pages of complex shapes Hansen-Smith has created. The How-to pages take you step-by-step through the creation of a sphere, a tetrahedron, an octahedron, and an icosahedron (16 triangular surfaces). Hansen-Smith clearly loves the math and can't resist slipping a lot of terminology into his instructions and pointing out cool mathematical features of the shapes-in-progress. That makes the pages very rich but a little hard to follow at first - don't let that scare you into thinking the shapes are hard to make.
http://www.omsi.edu/visit/tech/activities.cfm - click on "Robot Obstacle Course"
The Robot Obstacle Course presents you with a path, a robot, and a set of shapes on the path. You have to tell your robot to jump over certain kinds of shapes - say the "red squares" - by clicking to create a rule. The wrong rule makes your robot fall through a trap door, but you get to try again. The right rule gets you to the goal, and you are rewarded by a harder problem. The robot stops to "think" at each shape, comparing the shape to the rule you made. That makes the simulation go really slowly, but the problems are interesting.
Be a Police Sketch Artist
The Art of Crime Detection
This "artedventure" lets kids exercise their memory for faces and their descriptive powers - both verbal and visual. They are shown a face (the "criminal") and then asked to choose noses, eyes, etc. to try to produce a likeness of the face, as a police sketch artist would.
