1:32 PM | Teachers Leveraging Technology in the Classroom Panel Discussion
Do you think this conversation is happening in Finland,  that the Finnish Council of Teachers of Math is having sessions about leveraging technology in the classroom? -Karim Ani At the NCTM conference last week I attended a panel discussion and was struck by Karim's comment. He continued with "sometimes I'm a bit of Luddite because often times we use technology as a thing to pursue in lieu of the thing that we actually want to pursue." [That thing being children learning math.] It […]

1:00 AM | {6,3,5} Honeycomb
This is the {6,3,5} honeycomb, drawn by Roice Nelson. A 3-dimensional honeycomb is a way of filling 3d space with polyhedra or infinite sheets of polygons. Besides honeycombs in 3d Euclidean space, we can also have honeycombs in 3d hyperbolic space, a non-Euclidean geometry with constant negative curvature. The {6,3,5} honeycomb lives in hyperbolic space, and every vertex has 12 edges coming out, just as if you drew edges from the middle of an icosahedron to its corners.
