Students often use their books and their backpacks to hide the fact that they're texting on their phones or doodling in their notebooks. But what if they didn't have anything on their desks at all? Although some teachers ask their students to put their belongings on the floor, this can be a trip hazard. An easier (and safer) way to clear their desks is to attach letter trays to the bottom of their chairs.
This way, their belongings are still nearby, but they're not taking up any valuable space. Plus, you can pick these up super cheap from the dollar store, so you don't have to spend a fortune.
