  ***FEATURED DISCUSSION
  Smartboard and Geometric Constructions
  http://mathforum.org/mathtools/discuss.html?&do=m&thread=g_____g-19
  nickelljen asks, "Does anyone know if it is possible
  to do geometric constructions on a Smartboard? I just
  got the board this year and I can not find any
  information on it."

  ***FEATURED DISCUSSION
  Using Solver on TI-84
  http://mathforum.org/mathtools/discuss.html?&do=m&thread=c__dd___g-1
  Davem wonders, "Is there a way to store in memory the
  solution to an equation found using Solver, in order
  that it can be used in a follow-up calculation?"

  ***FEATURED DISCUSSION
  24 Game in Excel
  http://mathforum.org/mathtools/discuss.html?&do=m&thread=m6__hif_tool__g-1
  Don Link states, "Please take a look at my 24 Game
  implemented in Excel and give me any suggestions for
  improvement. Not only does it give random problems,
  it also displays all possible answers."

  ***FEATURED TOOL
  Tool: Geo-Calc
  BaldGeeks
  http://mathforum.org/mathtools/tool/25989/
  Macintosh shareware for calculating the area,
  perimeter, sides, angles, and other measures of two- and
  three-dimensional shapes such as ellipses, rectangles,
  triangles, trapeziums, parallelograms, polygons, prisms,
  cylinders, cones, pyramids, and spheres. If entered
  values do not describe a valid geometrical figure,
  Geo-Calc highlights the specific problem and suggests
  solutions. Also available in German and Norwegian.

  ***FEATURED TOOL
  Tool: Let's Count!
  Jayzeebear.com

  Click on the numbers and count the animals that
  are displayed.

  ***FEATURED TOOL
  Tool: Manny's Rumba
  The Learning Box
  http://mathforum.org/mathtools/tool/25920/
  Given a target number in the form of an equation
  "Make x = (number) blocks," move the base ten blocks
  (ones or tens) to the area showing the target number.

  ***FEATURED TOOL
  Tool: Pythagorean Theorem Lesson
  Angie Brock
  http://mathforum.org/mathtools/tool/21673/
  This interactive lesson (from eNLVM) compiles some of
