                      2018 MATHEMATICS GAME


 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.
