The National Library of Virtual Manipulatives (NLVM) is an NSF supported project that began in 1999 to develop a library of uniquely interactive, web-based virtual manipulatives or concept tutorials, mostly in the form of Java applets, for mathematics instruction (K-12 emphasis).
This website presents WebQuest-style math hunts. The math hunts connect to a variety of science or social studies topics: Antarctica, Earth Day, Human Body, Natural Disasters, the Rainforest, Black History, World Explorers, and numerous others. The math topics vary greatly from one activity to the next. Some are geared towards grades 3-5; others are more suitable for grades 6-8. Nearly all possible math topics are covered throughout the math hunts: decimals, percentages, ratios, measurement, algebra, fractions, basic operations, charts, graphs, averages, permutations, and countless others. There is a Teacher's Guide available with lesson plans, standards, objectives, and a skill chart. The skill chart correlates 16 math skills with math hunts for that specific skill.
