If I made a top ten list of websites teacher's need in their life, KAHOOT would be on it. The second time I used it a few years back I was in love. I say second because the first time I tried to make the kdis be quite why we KAHOOT'ed. I thought I could use the results for a grade. HA, silly me. The second time I didn't even try for quite and we all had a blast. It's intuitive to use and build quizzes. The new features are spectacular. My favorite thing to do is have kids write their own KAHOOT questions right after a first read of a text. This lets me know right away if the are getting what the text says. Then I follow up later with questions for deeper meaning.
