This site not only shares information about fractions, it shows you what your students can do/create. Wikis, (quick web pages) like this one can be made, edited, collaborated, shared, in just a few minutes or in one class period. If you want your kids to write or explain their understanding in math or any other subject, they now have the power to publish. Using a wiki to change and rewrite one’s own learning is perfect. Enjoy this one.
