GimKit

Recently I used GimKit as a platform to review with kids.  It is very similar to Kahoot, but it involves extra features.  You are allowed to ask questions and students can go through the quiz at their own pace on their own device.  While participating you are allowed to wager your points, use power-up features, making the game a bit more interactive as well as strategic.  I thought this would be a great resource especially with Math classes as you can tie in rish and logic.
