So, I think maybe my partner teacher came up with this idea to allow students to use a pen for the day. This is actually one of our QR Code Behavior Coupons that we use.
Over the past couple of years, I've gathered some pretty fun ones, so in response to a question from a teacher at Facebook, I decided to make a YouTube video to capture the craziness of these pens.
Hope you enjoy and hope it gives you some ideas for using this as a behavior reward in your own classroom. (And if you're on YouTube, please subscribe! I'm thinking of adding YouTube tutorials to my list of hobbies. :P)
