Peer assessment can be a bit bland if students don’t know what to look for in their friend’s maths work. Today @tesmaths tweeted a resource to help with this: these What Went Well bookmarks (free, sign-in required). I adapted them slightly since I’m more interested in students’ mathematical communication than in their neatness. Here is my version of the What Went Well bookmarks. These are in a PowerPoint file and are double sided, five to a sheet.
