Math That Makes You Squirm!

Stumbled upon this math resource last night while Christmas shopping and took a closer look.  I like what I see!  It's math with an edge, a squirmy, icky, slimy edge that I bet a few kids out there might cotton to - especially if those kids happen to be boys in the 9-14 age range.

It's Alive and Kicking: Math the Way it Ought to Be;Tough, Fun, and a Little Weird

Hone your math skills by figuring out how much cow manure is produced in the U.S. over a certain period of time, how many times your blood vessels could be stretched between LA and New York, how many coffee cups worth of sweat is generated by certain activities..........how gross can it get?  Apparently kind of gross, but still, thought-provoking for the right child who also happens to enjoy a twisted sense of MATH.  Eeewww. 

Probably a good math match for a 5th, 6th or 7th grader who is looking to get kind of grossed out.  I think I might know a kid like that!  Have fun checking these out.
