Gearing up for a twenty-second year, the Math Forum's Year Game
puzzle returns this January. We'll be looking for students to
write expressions for each of the counting numbers 1 through
100 using--

- the digits in 2018;
- standard operations; and
- grouping symbols.

Preview this year's complete rules, worksheet, and
manipulatives now. Starting Monday, January 1, 2018,
students may submit solutions, which we'll start displaying
February 1.



What shape would be traced by a point on a ball rolled across
a surface?

That question inspired the creation of geometry software
called Engare, released last week. "It's been a while since a
game made me cry simply by being beautiful," tweeted the tech
culture editor of Ars Technica, a website covering news and
opinions in technology, science, politics, and society.

Engare challenges players to match a target glyph by tracing
shapes on progressively more complex moving objects. The
software, which is part spirograph drawing tool and part game
of parametric and polar mathematics puzzles, allows players to
export their mosque tile-like patterns as images or
three-dimensional models.

Creator Mahdi Bahrami describes his latest oeuvre as "a
meditation on the dynamics of simple machines and the beauty
buried deep within repeating motion." Watch trailers and game
play videos, then purchase the PC or Mac OS software from the
Steam platform for $6.99.
