Educational consultant and textbook author Jill Britton is the author of these metasites listing Web resources for grade 5-8 mathematics. Each metasite revolves around a certain topic. For instance, the first site, Number Patterns Fun with Curves & Topology, is an index of eighteen subtopics such as prime numbers, the golden ratio, Pascal's Triangle, mazes and maps, etc. Under each subtopic, an annotated list of Web resources (from other authors and organizations) points to tutorials and fun activities for students as well as printable activity sheets and lesson plans for teachers. Other types of links given on these pages are to merchants selling educational materials, sites on the history of mathematics, and activities with holiday themes.
