Plickers is a rapid-response classroom-polling app that uses paper cards rather than mobile devices for student responses. There are iOS and Android apps as well as a web interface. This is a great way to integrate technology into low-tech classroom settings.
How can I use Plickers in my classroom?
Plickers can help teachers revamp exit tickets and daily class openers; students will start or end class in a meaningful, engaging manner so long as the teacher creates insightful, thoughtful questions. Give students the autonomy to create questions to be used for quick reviews of information or texts. Preview upcoming materials to gain footing on where to start the unit. Test-drive quiz and exam questions as a litmus test for summative assessments. Need a little pick-me-up in class discussion or behavior? Create brain-stretch questions to jump-start the class. – Common Sense Education
