Padlet

Padlet is an online notice board that can be used by students and teachers to post notes such as links to websites, photos, videos and documents on a common page. A class can be split into groups and work on an exercise together then post answers or responses on what almost looks like flipcharts. A bigger group can come back and see each others answers in a very clear visual way on the one screen.
