This is my first Kahoot. I've used it a few times so far in classic mode (?), where each student participates using their own tablet and the questions are screened on the blackboard. In my classes the students worked in their study groups.There is a worksheet that mirrors the kahoot quiz, so that students have something to take away from the class. If the students play in group mode, it will probably take longer, depending on the pace of the group. I told the students they could use their textbooks during the quiz. I found that it was really important (through trial and error) to stress that nick names for kahoot should not be versions of the student's own name. The anonimity seems to encourage most, if not all, students to answer.
Please test run this kahoot yourself before using it in class. If you have any sugggestions for improvements, I'm all ears.
Note: paid version of Kahoot
