Combining the digital world with some physical manipulates, Plickers is a blast for everyone involved. It is pretty easy to set up as well. You will need to print Plicker Cards from the Plickers website. There cards look like QR codes. For my classes, I print and laminate the cards, writing the students names on the back for easy distribution. I have seen this procedure done various ways however. Next year my plan is to tape the plicker cards to my students' social studies notebooks, so they always have them. Anyways, once you have your cards you will need a phone with the Plickers app installed. You can add questions from your desktop or from your phone. Plickers allows you to ask multiple choice questions (content or opinion based) by scanning your students QR codes. Students hold up their cards in a specific direction (depending on what they intend their answer to be). It sounds confusing, but its super easy and is a great way to assess the kids on the spot. Plus its fun!
