Our pupils created the multiple-choice questions for our Collaborative Kahoot. They were shared on a doc where they had to highlight the right option (out of 3 or 4 possibilities).This is the link to the google doc with the answers from the 7 partner countries, which the students had no access to (each teacher filled in their hero's part). When it was ready, the students played the game, which was about what they actually studied or researched!
