                 Two of Suzanne's Favorite Things
    The National Math Festival App | The Desmos Geometry Tool




 Three days after the close of the NCTM Annual 
 Meeting & Exposition, Math Forum senior project manager 
 Suzanne Alejandre blogged about two troves of resources for 
 math teachers.

 Before the San Antonio conference, scores of Problems of the
 Week, along with their supporting materials, went live on the
 NCTM website for members to access. Just log in to,
 mouse up to the purple navigation bar, and click on "Classroom
 Resources" for 62 sets of PoW resources:


 Suzanne also highlighted all the new content collected from
 the Networking Lounge in NCTM Central this past Wednesday
 through Saturday:

                    THE DESMOS GEOMETRY TOOL


 On Sunday, Desmos announced the beta release of its first
 geometry tool.

 Acknowledging the many choices that are already available in
 dynamic geometry software, Desmos posted on its blog to make
 the case for what sets apart its new lightweight,
 browser-based tool. The creators of the popular free online
 graphing calculator welcome feedback by email to and by tweets to @desmos.

 Soon, the Desmos Geometry Tool will appear in products from
 Pearson and College Preparatory Mathematics. To suggest
 partnerships with other math education organizations, email
