Kahoot is a free website that allows you to poll or quiz your students using ANY DEVICE! This eliminates any problems with students having different types of devices. Kahoot is easy to use and completely free. It brings your class together and serves as a motivational review game for any grade level. This lesson, as all of my lessons do, provides you with step by step directions on how to use the tool as well as a screencast showing you exactly how to use the tool.
