2010 Mathematics Game
http://mathforum.org/yeargame/2010/
Write expressions for each of the counting numbers 1 through
100, using the digits in the year 2010, standard operations,
and grouping symbols. You may use the digits in any order, but the order 2, 0, 1, 0 is preferred. This year we will also allow the use of
decimal points and doubledigit numbers. This puzzle is
appropriate for students in grades 312 with a general
knowledge of mathematics.
Students may use the Web form to submit solutions starting
January 1, 2010; revisit the site after February 1, 2010, to
see the first solutions.

The Geometer's Sketchpad 5.0
http://www.keypress.com/gsp
The Geometer's Sketchpad® is a dynamic construction,
demonstration, and exploration tool that adds a powerful
dimension to the study of mathematics. You and your students
can use this software program to build and investigate
mathematical models, objects, figures, diagrams, and graphs.
Beyond innovations in performance and usability, such as video
gamequality graphics and advanced data handling, Sketchpad 5
offers:
 Transformable Pictures
 Hot Text™
 Marker Tool
 Expanded Algebraic Capabilities
 Expanded Geometric Capabilities
 Improved Display
 Integrated Support and Curriculum
See a full list of features on the site above, as well as
introductory videos and classroom materials.
You can download the software for free, but until you get an
authorization code it's limited to 20 minutes at a time, and
cannot save, copy, or print. There is a charge for upgrading
from an earlier version; see the web page above for details.

You'll find Scott Steketee, former math and computer science
teacher and current member of the Sketchpad team, posting on
the dynamic geometry discussion, hosted by the Math Forum. This
is a discussion of such geometry software programs as the
Geometer's Sketchpad and Cabri Geometry II. This group talks
about ways of teaching using this technology and the behavior
of these programs in specific situations, and sometimes shares
sketches.
Registration is free.
