Three dimensional solid geometry has nearly been written out of the American mathematical curriculum. Yet my middle-school math team is approaching the last and most difficult math meet of the year where, among other things, they are expected to know basic solid geometry.
So for the 3d-unaware student I have put together a super-compressed introduction to the basics of middle-school solid geometry, with a high level of challenge for intended for math team middle schoolers who are trying to learn everything they need to know in a week. The packet here has only 4 pages and 27 problems, with an extra 6 pages for solutions to check after you are done. The easy bits are skipped, and in exchange you get to see some common types of tricks as well as a hint of insight beyond basic prisms, pyramids, cones and spheres.Posted by David at March 8, 2010 01:10 AM
