The perfect counterpart to Kahoot!
This is a fantastic resource for teachers to have in their toolbox. It's easy to find a pre-created quiz or make one yourself. As with any tool like this one, its service to the students and your teaching depend on how it's used (a lighthearted game to lift some spirits, for student review, or formative assessment, just to name a few.) Some of my favorite features include the auto-generated avatars, post-quiz data, and the memes at the end of each response - they are really funny!
How I Use It
This is my latest recommendation to the teachers and administrators I work with. The site is great because it works on any device. It also allows students to work at their own pace (within a set timer) without the pressure of just clicking any choice to answer quickly. The questions display on each student's device and student progress displays on the teacher device, so you don't need a projector to use it. I haven't run into anything that "hasn't worked" yet.
