Plickers
Plickers lets you poll your class for free, without the need for student devices. Just give each student a card (a "paper clicker"), and use your iPhone/iPad to scan them to do instant checks-for-understanding, exit tickets, and impromptu polls. Best of all, your data is automatically saved, student-by-student, at plickers.com.
Happy teaching!
