2 Our learning intentions We are learning to fold unit origami and see geometry concepts that connect to it. I will be successful when... I can brainstorm geometry words related to unit origami. I can try out a vocabulary method that promotes understanding. I can notice geometry concepts that can be taught using origami and find several concepts that relate to my grade level content. I can fill out a chart to analyze faces, edges, and vertices. I can build a unit piece, cube, and possibly a triangular hexahedron. ( I may even be able to build a stellated octahedron or start it.) I can reflect on the benefits of using origami as a way to embed math and set goals for future steps I could possibly take to teach origami. Some may take additional steps:

3 Our Norms for the Session Today Have a growth mindset while working on origami today. Take care of and reach out to the people next to us. Take the role of origami folder A and origami folder B when necessary. Stop on a three, two, one when I use the hand signal. It will save us much time and promote a respectful atmosphere. Simulate what it takes to teach up to 35 students origami at the same time. Put phones and technology to the side except during our work time. Engage, focus, and participate at a level that you would expect if students were watching you. Enjoy and learn

6 Growth Mindset and Origami Challenges Growth Mindset Findings from my Action Research Teaching students about growth mindset impacted the challenges that students were willing to tackle in my advanced math class. Those students surveyed who reported a growth mindset finished more of the challenging origami polyhedra than those who believe that their math intelligence is fixed. For the first time since starting the advanced math class four years ago, all students finished the stellated icosahedron. Most students in the class created more challenging additional origami pieces. Those who reported a fixed mindset on the survey did not take on additional challenges. They tended to try to hide that they were stuck or didn t know how to proceed. Quote echoed in various wordings. I think that if I told myself at the beginning to ask questions, I would have had a lot smoother way through this. I really have to let myself know that asking questions doesn t mean giving up. It means that I m actually stronger. A way that I have grown as a teacher is to make my classroom a safe place for adolescent learners to admit that they don t know something, are stuck, and need help. Tips Origami is the perfect tool for helping students learn the skills they need to have a growth mindset. Student Quote When I made the cube, at first I didn t think I could do it, but when I finished the cube easily, it changed my mindset. I think I could have had a better mindset at the very beginning. I wasn t very enthusiastic, but I ended up loving it.
