Symbaloo

Symbaloo is an online bookmarking tool that helps you organize sites you visit often and makes them easy to find from any device. Users can create multiple webmixes to organize their bookmarks. These webmixes can be made public or shared with select groups of people. This is a great way to provide students with a group of web resources on a topic. Teachers can make their web mixes public and share them with students using a QR Code.
