Use for brainstorming, mind mapping and affinity mapping. Students can use Bubbl.us to create a visual representation of their understanding at the beginning or end of a topic. Teachers can run a brainstorming session with students, then share the results with students as an image or read-only map.

Check out this introduction to Bubble.us, and read through the Bubbl.us help pages. Bubbl.us works on all major web browsers except IE11.

Go to the Bubble.us home page and click on "Start brainstorming". You can register using your education.nsw.gov.au Google account, and have up to three documents at once without paying. If you want your students to collaborate on a map themselves you will need to pay the basic subscription fee.
