Thinking back to my readings about math class norms from Mathematical Mindsets, I decided to create a video to summarize what I want my students to walk away from the Post It Activity knowing I believe about them. It's brief and will ensure that all my classes are hearing a consistent message from me. Once we wrap up our class discussion, I'm planning on playing this for them and having them reflect as an exit ticket.
I have the file saved if anyone wants me to send it so it can be tweaked! Like Cathy, I used the free trial of VideoScribe to create this! It's super user-friendly!
