Here's what Curriki has to say about itself:
Curriki is more than your average website; we're a community of educators, learners and committed education experts who are working together to create quality materials that will benefit teachers and students around the world.
Curriki is an online environment created to support the development and free distribution of world-class educational materials to anyone who needs them. Our name is a play on the combination of 'curriculum' and 'wiki' which is the technology we're using to make education universally accessible.
Curriki is the result of work done for GELC - the Global Education and Learning Community - an online project started by Sun Microsystems to develop works for education in a collaborative effort. The leadership team consists of people with a long-time commitment to exploring the use of technology to improve education.
Most of what I reviewed was quality instructional activities, websites and resources.
If you are looking for new ways to present your curriculum this website could be your new best friend!
