[ The 12/31 article is at Equalis. Here is the previous one. ]

Welcome to the Christmas Eve edition of Wild About Math Bloggers!

I've announced the winner of the TI-84 Plus Silver Edition Giveaway contest. Daniel Chiquito takes the prize. And, he read about the contest at my Equalis Blog!

The Math Teachers at Play Carnival is up at the "Old Math Dog" Learning New Tricks blog.

Peter Rowlett, at "Travels in a Mathematical World" has an interesting discussion of the historical use of "math" vs. "maths." Data for the analysis comes from the Google Books Ngram viewer.

Pat Ballew at Pat's Blog has a nice exploration of "decimal" fractions in other bases. This is a good article for getting grounded in what a base actually is, what a fraction is, and what division is. Nice job, Pat!

Maxwell's Demon has a nice post, Islamic Geometry:

Marc Pelletier is a geometric artist, one of the visionaries behind the amazing Zometool system and the designer and builder of 120-cell models including one given to John Conway at Princeton and one at the Fields institute (given on the occasion of Coxeter’s 95th birthday). More recently he has been working on Islamic tiling patterns, drawing on the work of Jay Bonner, an expert on the geometric art of the Middle East. ...

Robert at Casting Out Nines has an interesting article, "Misunderstanding mathematics." Robert reviews an essay by Professor Lewis at Fordham University. Here's an inspiring piece from Lewis' essay:

…the notion that mathematics is about formulas and cranking out computations. It is the unconsciously held delusion that mathematics is a set of rules and formulas that have been worked out by God knows who for God knows why, and the student’s duty is to memorize all this stuff. Such students seem to feel that sometime in the future their boss will walk into the office and demand “Quick, what’s the quadratic formula?” Or, “Hurry, I need to know the derivative of 3x^2 – 6x +1.” There are no such employers.

Denise at Let's Play Math tells us about a great game, Graph-It, that should get kids interested in graphing points on a grid.

To play Graph-It, one person designs a picture made by connecting points on a coordinate graph. He reads the points to the other player, who tries to reproduce the picture.

And, there's a nice Christmas puzzle that even adults might enjoy!

I will leave you with a couple of cartoons that ClimeGuy Ihor found.

I wish you all a Merry Christmas! I'll "see" you all next year.
