Tessellation Madness

I found two awesome resources for teaching tessellations: this is super cool for taking your kids down to the computer lab and quickly creating their own custom tessellations handouts, followed by this as an uber-fun tessellations project. (I am going to add more parts to the tessellations project, obviously. Minimally, before the kids can get to the cool cartoon tesselations, they'll have to show me that they can tessellate by hand triangles and quadrilaterals. I'll probably write more about it once I know how well it works out in my classes.)
