***FEATURED DISCUSSION
Imagine Cup winners!
http://mathforum.org/mathtools/discuss.html?&do=r&msg=167512
Suzanne adds to an ongoing discussion, "The MathDash team 
reported that they won the United States Imagine Cup! Read more 
about Team Drexel Dragons: Matt Lesnak, Keith Ayers, and N. Taylor 
Mullen.... Next they'll be competing in the World Championship 
in Sydney, Australia in July!"

***FEATURED TOOL
Tool: Sushi Monster
http://mathforum.org/mathtools/tool/167516/
Scholastic
Practice, reinforce, and extend math fact fluency with this game,
which strengthens reasoning strategies for whole number addition and
multiplication by helping monsters make a target sum or product. To
succeed, students need to plan ahead and strategically select numbers
from the sushi counter.

***FEATURED TOOL
Tool: Differentiating Powers of x (polynomials)
http://mathforum.org/mathtools/tool/167513/
Ron Barrow
This applet investigates differential calculus of powers 
of x (polynomials). You can plot the primary function ( ?(x) ), 
its first derivative (differential, the gradient function) ( ?'(x) )
and its second derivative ( ?''(x), the gradient of the gradient ) 
side by side for comparison. Use the applet to investigate 
increasing and decreasing functions, maximum, minimum and other 
turning points. See how the first and second differentials vary
with the primary function.

***FEATURED TOOL
Tool: Online Calculator
http://mathforum.org/mathtools/tool/167058/
Amir Rashedi
Use this online calculator to calculate mathematical expressions and
complex numbers. You can also calculate zeroes of functions, generate
a table of values for a given function, and do polar graphing.
