Clicker technology was, thankfully, a short lived phenomenon. Although I got great information for the $1600.00 clicker set I had in my classroom back in 2006, they have lost relevance. Why would you buy an expensive single-use tool like a clicker, when there are free, fun and flexible tools out there ready for you and your class to use any time?
Kahoot is one of the more fun players in the mix. It allows you to easily create, manage and share questions, while collecting helpful data. Best of all, your students can interact with Kahoot from any web-enabled device.
