This document discusses using social media tools like blogs, wikis, Twitter, Facebook, and email for teaching mathematics. It provides examples of how each tool can be used, such as using blogs for explanations of concepts, embedding class materials, and practice problems. Wikis are suggested for problem solving, real world math problems, and collaborating with other schools. Twitter is best for announcements while Facebook groups allow students to post on a class page. Email can include math notation if students have MathType. Overall, the document introduces social media tools and strategies for incorporating math into each one to engage students.
