Happy New Year! We got a jump start on one of our new year's
resolutions -- re-solving the problem some of you had when
attempting to post to the discussions. To those of you who
experienced a "hanging" browser that made it seem as though
and are happy to report that we have resolved the problem.

We are hoping that the new year brings many interesting
discussions to Math Tools. Feel free to start a new discussion

***FEATURED DISCUSSION
Midsegment of a rectangle?
Cynthia asks, "I remember having discussions with mathematicians
that trapezoids should include the family of parallelograms.
Do you agree? Then should it also include the family of triangles?"

***FEATURED DISCUSSION
Upper middle schoolers that haven't yet mastered multiplication facts
Bethy writes, "We have a number of students who, at 7th and
8th grade, still don't know 75% or more of the multiplication
facts. What does the research indicate? Does anyone know of an
effective method for equipping these students with a procedure
so that they can move ahead?"

***FEATURED TOOL
Tool: Colouring Sides 1
Freudenthal Institute
http://mathforum.org/mathtools/tool/16727/
This tool presents a 3-d drawing along with four 2-d views.
Choose the one 2-d figure that corresponds to the colored face
on the 3-d figure. These exercises in spatial visualization
become more challenging with each new set of drawings.

***FEATURED TOOL
Tool: Zap it Game
ExploreLearning
http://mathforum.org/mathtools/tool/16740/
Commercial site with one free access per day. Students are
given a set of points and are asked to "zap" as many points
as possible. They can use either polynomial form or vertex form.
Students can get a line by setting "a" equal to 0. New points
can be displayed and then the student can try again.

***FEATURED TOOL
Tool: Poisson Experiment
Department of Mathematical Sciences
University of Alabama at Huntsville
http://mathforum.org/mathtools/tool/16460/
This applet allows the user to fix a rate and time interval
for a Poisson process (counting the number of occurrences in
a fixed time interval). Experimental and theoretical results,
including expected value and standard deviation, are shown.

***FEATURED TOOL
Harcourt School Publishers
http://mathforum.org/mathtools/tool/16242/
Students practice addition facts by dragging the given numbers
onto the Fact Table to a box where the row and column add up
to the given number. A free preview activity from Harcourt
School Publishers.
