MathFlix is a resource of over 1000 videos sorted by topic. The site also includes over 400 downloadable worksheets that reinforce concepts and provide additional practice. The videos themselves are hosted at many different locations on the web, but this index makes it easy to find them by math topic. Enter the site by choosing either the "I am a teacher" or "I am a student" icon. The teacher link lists topics by standards and content within each standard. Choose from Number & Operations, Algebra, Technology, and more. Each of these links leads to further subcategories listing video titles to view. The student link leads to clickable images or words, including topic and subcategory. Choose one of these links to go directly to the list of videos available for that topic. Be sure not to miss the links at the bottom of the page. They aren't quite as obvious as information for the videos; however, they include additional information relating to Common Core, assessment, and curriculum support.
