They are focusing initially on developing an online repository for K-12 curricula in the areas of mathematics, science, technology, reading and language arts, and languages. They want this repository to attract everyone from educators, students and parents, to programmers, instructional designers, authors and public officials throughout the world to contribute or freely access quality learning materials. (A very similar concept to Wikipedia, which most of us are familiar with.)

You can find lesson plans, teaching activities, student worksheets and more. You can contribute by sharing your favorite curriculum resources. You can collaborate with teachers in your school or educators around the world. If you join (it’s free) you will be able to collect resources in a personal collection, to modify those resources to meet your specific needs, to contribute your own resource information, and to participate in the educational community by providing feedback and comments.
