***FEATURED DISCUSSION
Smartboard and Geometric Constructions
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
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
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
the resources found here in the Math Tools Digital
Library and also off the Internet to teach about the
Pythagorean theorem. Sections include Objectives,
Introduction, Explore, Pythagorean Proof, Another Proof,
Still Another Proof, Using the Pythagorean Theorem,
Applications, Pythagorean Explorer, and Quiz.

***FEATURED TOOL
Tool: XP Math: Comparing Fractions
T.L. Hui
http://mathforum.org/mathtools/tool/22429/
To compare fractions, you may either a) rewrite
