Plickers is an interactive poll system that provides teachers with a unique way of gathering answers or opinions from students. Data is collected through special printable cards that display a unique shape, similar to a QR code, that the iPhone can recognise when scanned.
The shapes are numbered for identification purposes to allow you to assign them to students — thus telling you who voted what. Each side of the shape displays a tiny letter (A,B,C,D) so only the person holding the card knows their answer. The iPhone then scans all the shapes and displays everyone’s answer on screen.
