I told my eldest daughter (11yo) facing a new school and new teachers (including some crazy bad ones) that we will celebrate her first bad grade with a party.
(unfortunately she didn't appreciate it... but seriously... a party! I don't know what they teach to kids these days! 🤦♂️ )
You might do the same with your students if you got a bad evaluation.
Eating a piece of cake to celebrate "the weird teacher's first bad grade" might be an highly educational experience. 😉
