The Department of Mathematics of the University of Washington offers the Probability Abstract Service. This archive of research article abstracts covers a variety of topics in mathematics. Everybody is welcome to submit abstracts, so the diversity of submissions is great. The abstracts include either links to a full report or email addresses to contact authors for a copy.

Visual Fractions is "a tutorial that offers instruction and practice in identifying, renaming, and operating on fractions" and was created by Richard E. Rand. The website reviews examples of fractions, which are modeled with number lines or circles. Throughout the website are instructions to follow, encouraging students to try a few activities on their own. For a more light-hearted approach, Rand...

Perhaps readers have heard someone struggling with a math problem and grumbling, "When will I ever use this?" Perhaps, readers have said this themselves. We Use Math provides an answer (several answers, in fact). The site is a resource for mathematics educators and learners, and the content focuses on highlighting "careers in math" and "careers using math." A quick browse of either section makes...

Zona Land, created by Ed Zobel, is a science and mathematics resource site for students and teachers. The site illustrates mathematical and physical principles by the use of Java applets and VRML simulations. The Science section contains the Physics Department (mechanics, waves and light), EZ Graph, and EZ Evaluator. EZ Graph allows the user to view the graph of a desired function. Evaluator is...

The What Works Clearninghouse was established by the U.S. Department of Education's Institute of Education Sciences "to provide educators, policy-makers, researchers, and the public with a central and trusted source of scientific evidence of what works in education." The What Works Clearinghouse (WWC) has posted the results from its review of “interventions based on a curriculum, which contain...

This interactive article from the Why Files reports on a recent study by Daniela O'Neill, professor of psychology at the University of Waterloo in Ontario, which examined the relationship between language ability and skills in mathematics. The author discusses the findings and points to some interesting directions for further investigation. In particular, "the study suggested that certain...

Wolfram Research, creators of Mathematica software (see also NSDL Report for Math, Engineering, and Technology, July 16, 2004), have posted this gallery of images that demonstrate how "Mathematica has opened the door to a new kind of imagery that melds art and science." The colorful images in the gallery, created by Mathematica users around the world, are grouped by type: 2D Graphics, Polyhedra,...

Mathworld, hosted and sponsored by Wolfram Research, Inc., is an online mathematics encyclopedia intended for students, educators, math enthusiasts, and researchers. This amazing resource was compiled over 12 years by Eric Weisstein with assistance from the mathematics and Internet communities, and continues to be updated. (Weisstein also authored the ScienceWorld site, which contains material...
