Created as part of the Mathematical Association of America's (MAA) outreach efforts, MathDL Mathematical Communication is "a developing collection of resources for engaging students in writing and speaking about mathematics, whether for the purpose of learning mathematics or of learning to communicate as mathematicians." The site contains materials on giving successful math presentations, talking about math to a diverse audience, and also communicating effectively with teammates working on a math project. Visitors shouldn't miss the Resources for Presentations: Handouts & Links area. Here they can find how-to-guides such as "Preparing a Poster Presentation" and "How to Give an Effective Math Talk." Also, visitors are encouraged to submit their own resources for possible inclusion on the site. The site is rounded out by a nice primer titled "Introduction to Teaching Math Communication." [KMG]
