I used Kahoot a lot last year with my 4th grade because they all had Chromebooks in the room. They loved this and asked to play it all the time. It was a good way to review a unit. Competition is always good and gets them into what you are working on!
I tried this for the first time with my second graders the other day. They LOVED it and wanted to keep going! The only issue is the ones that just click and answer and don't try!
I've been meaning to use this with my 4th grade library lessons! I could use it when I work on the Dewey Decimal System, but I'd like to see if I can figure a way to use it when I'm teaching about the online catalog...we'll see what I can make work!
I haven't used it yet, but I wonder how kindergarten will do dealing with the timer. I will probably just use pictures more than anything. Can I set up the students on the iPads?
