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. -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- ENGARE http://www.engare.design/ 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. http://store.steampowered.com/app/415170/Engare/ -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- CHECK OUT OUR WEB SITE: The Math Forum at NCTM http://mathforum.org/ Online PD http://mathforum.org/pd/ Online Workshops http://mathforum.org/workshops/ Ask Dr. Math http://mathforum.org/dr.math/ Problems of the Week http://mathforum.org/pows/ Powerful Problem Solving http://mathforum.org/pps/ Mathematics Library http://mathforum.org/library/ Math Tools http://mathforum.org/mathtools/ Teacher2Teacher http://mathforum.org/t2t/ Discussion Groups http://mathforum.org/kb/ Join the Math Forum http://mathforum.org/join.forum.html Ask Dr. Math Books http://mathforum.org/pubs/dr.mathbooks.html Facebook https://www.facebook.com/themathforumatnctm/ Blogs http://mathforum.org/blogs/pows/ Twitter Feed http://mathforum.org/pd/twitter.html SEND COMMENTS TO: http://mathforum.org/electronic.newsletter/mfin.faq.html#feedback _o \o_ __| \ / |__ o _ o/ \o/ __|- __/ \__/o \o | o/ o/__/ /\ /| | \ \ / \ / \ /o\ / \ / \ / | / \ / \ An archive of all the Math Forum newsletters and directions for subscribing can be found at http://mathforum.org/electronic.newsletter/ ```
