The idea behind Maths is Fun is to offer mathematics content as well as some fun and combining the two wherever possible. Mostly basic content on here, but most basic math content can be integrated into more complex secondary mathematics subjects.
Interactive Math activities by grade level and category: Number, Data Analysis, Geometry, Operations, Probability, Measurement, Time and Money, Algebra
"Educational games are a great tool for building foundation math and language skills that today's elementary school curriculum requires. These online learning games and songs for kids are fun, teach important skills for preschool and elementary school kids and they're free. Want educational games that help build skills in math, language, science, social studies, and more? You've come to the right place!"
National Geographic Maps: Tools for Adventure is the best everything-map site I have seen. The site was created by the Children's museum of Indianapolis. Maps are presented as the keys to adventure. Students learn to use maps to find their way, share information, look at patterns, and solve problems. There are six excellent interactive games for students to practice putting their math skills to use. Students can explore a pyramid by guiding a robot to hieroglyphs, find sunken treasure, explore Mars, go on an adventure, see GIS in action, and visit Adventure Island. I love the realistic feel of these games, as students explore and guide robots, they get a "live" video feed of where they are navigating. On the National Geographic Maps: Tools for Adventures site, you will find information about the Indianapolis exhibit, how to use maps, related map links, and lesson plans. This is one of those websites that my description just won't do justice to, be sure to check it out!
