Mathwords's accurate definitions could be useful for advanced students who just need a nudge to remember a particular aspect of a term, but kids needing a bit more hand holding who will likely be stymied. Definitions are overly concise, contain a plethora of references, and assume basic foundational understandings. For instance, the entry for three dimensional space never uses the terms height, width, or depth though it does refer to three-dimensional coordinates. Textual explanations are rare and more attention is paid to "formal" meanings than making the material clear, especially to kids who are already having a hard time. And most examples, if present, are actually diagram images pixelated beyond recognition.

About twenty terms are accompanied by a cool JavaSketchPad, QuickTime, or LiveGraphics3D-based dynamic diagram from McGraw-Hill's Geometer's Sketchpad, but even these lack sufficient labels and took nearly 5 minutes to load. Overall, accessibility is a problem for the kids who need this site the most.

Did we miss something on diversity?

Research shows a connection between kids' healthy self-esteem and positive portrayals in media. That's why we've added a new "Diverse Representations" section to our reviews that will be rolling out on an ongoing basis. You can help us help kids by suggesting a diversity update.
