One of my first forays into technology games was Kahoot! 

This is basically an online quiz game format that includes catchy music and all the elements of a suspense-filled, nail-biting trivia race.  With Shirany Y. we came up with a Google Slides Presentation to outline the basics of Kahoot! and how to begin creating your own Kahoots!....
or just borrow other's Kahoots! when you're short on time.

My kids love it!  

This is great for high school students if you have a class where everyone has their own smart phone and can play independently or if you have tablets where students can play in teams.  

I have come to really like this quiz format and use it in class regularily.

I encourage others to have fun with it too!
