heey! that is a very cool thing to see ! being a teacher myself I also like to challenge my students into various games.. (i'm a music teacher ) but sometimes between classes I'll set up a game just to keep them lured in. One of my favorites is the ''random drawing contest'' .. which we basically ask for a random thing and a random action.. and we might end up drawing stuff like a ''turtle on a motorbike'' or a ''kangaroo eating noodles'' .. whatever .. some very creative drawings are born . Kids are naturally creative in my opinion , you just need to poke the motivation out a bit. :)
