       MATH TOOLS NEWSLETTER - MARCH 4, 2006 - No. 37    

Are you planning to visit St. Louis, Missouri, to attend   
the National Council of Teachers of Mathematics 84th Annual   
Meeting, April 26-29, 2006? If you are, we'd love to have   
you stop by Booth 630 in the exhibit hall, or attend one   
of our sessions:                                       


To keep up with the growth of Interactivate, The Shodor   
Foundation seeks to change the site's underlying technology,   
as well as its browse and navigate features function.    
They invite users to peruse the prototype and complete a   
feedback form, which registers you in a drawing to win   
an iPod.                                    


As part of our participation in the Engaging People in   
Cyberinfrastructure (EPIC) project,   
we are cataloging Spanish versions of Interactivate that   
were translated by Eduteka. See the entire Spanish site at
