Beautiful Oops is one of my favorite books! It's all about looking at "mistakes" in a different way - as an opportunity for creativity and a new perspective.
I've used this with students who struggle with perfectionism and anything that is unexpected. We started by reading the book, then I picked students at random to choose a "mistake" from my table (examples below). The students had to take their paper and turn it into something beautiful. Some of my students struggled, but all of them were able to complete the task. 1 student was absent, so there isn't a finished product for the crumpled paper.
We finished the session with an overall reflection on the topic.
