Have you heard of Plickers? This is a new app that works on all platforms, which is a clicker without a clicker. You download a set of A6 cards which have unique shapes on them. The orientation of the card corresponds to a multiple choice letter (A-D, or however many you want to add). You open the app, point your device at them and it records the answers – if you have a class set up, it keeps a record of the answer against each child. You can create questions on the fly, or prepare them in advance. Definitely worth checking out! This is the low tech high tech solution to exit polls.
