The TikTok trend of stealing & trashing school property is straight up embarrassing & unacceptable! So over social media outlets allowing such junk to trend. Nothing to celebrate or trend!

#MASHteach I used this approach many times! It is a humbling reminder of both the validity of your assessment and the focus of your teaching. Most importantly it is a fair opportunity for students!
