Hi Jim - this is a lot of fun! I especially liked My daughter’s 7th-grade class enjoyed the fact that 10 * 0.3333 = 3.3333 = 3 + 0.3333 or (vulgarly) 10 = 3 + 1/3 or the abomination 10 = 3 1/3 I did this as a warm up for summing geometric series. - Cris

I've written something different for this month: a (mostly) tongue-in-cheek promotion for an upcoming mathematical holiday called "Thirdsday". (The holiday is bogus; the math is real.)
You can read the current draft at http://mathenchant.org/043-share.pdf .
Suggestions are welcome, especially suggestions for mathematically interesting occurrences of the number 1/3. (I'm saving "the volume of a pyramid is 1/3 times the area of the base times the height" and "the integral of x^2 from x=0 to x=1 is 1/3" for the next Thirdsday, just over a decade from now.)
