During our Forest of Reading celebration I had students create their own mythical creatures (using all the old scraps of makerspace materials from the rest of the year) and we got some great ones! I really like the idea of using a fun tool like this though, as I think it would really help focus those students who have a difficult time coming up with an idea. For many students, ideas just seem to come naturally but for those who really struggle, this makes so much sense. I think I will try and remember next year to have an option of a creating something online first to help students who are feeling 'stuck', to 'unstick' themselves!
